With the onset of winter cold weather, many car owners face a problem: how to start? Probably, there is not a single driver who would not ask to "light up" at a sudden stop of the battery no one is insured. There are many reasons for the discharge and breakdown of batteries. Before deciding on specific actions, you need to familiarize yourself with all the details.

Reasons for a dead battery

There may be several of them:

1. Expiration of battery life;
2. Battery breakdown;
3. Untimely battery charging;
4. Incorrect operation, frequent recharging.

How to start it? What to do if the car battery runs out in the middle of the way? These questions are of concern to many. Most batteries lose their charge during cold weather. This is facilitated by a sharp change in temperature conditions. The cold season is not good for the device. This is especially true for cars that are on the street for a long time. The load is also of no small importance for operation in the cold season.

If the load is excessive, it is natural that the device will discharge faster and this will lead to a decrease in its shelf life. You can get out of this situation.

Extend battery life

Ways to Minimize Battery Damage:

• correct operation of the vehicle, which provides for proper care at subzero temperatures. In other words, the car at low temperatures can be left in the cold only if the battery is removed from it;
• do not leave vehicles unattended for a long time;
• when the battery is discharged, it is necessary to provide an emergency charging method or have a spare;
• you can try to "light" the engine or ask other motorists to do it;
• use special for quick

There are times when it is impossible to count on someone's help and only a special device can help. Therefore, the best way out of this situation is considered to be a one-time expenditure on the purchase of charging equipment.

Devices for starting the engine with a dead battery can be varied:

• asian origin;
• european;
• cIS countries.

Sometimes a car jump starter is called a booster. Unknowing people consider this device to be auxiliary.

But they are deeply mistaken. This is a completely separate equipment with certain quality characteristics:

• its capacity is much less than a conventional battery;
• the internal "filling" is also different;
• gives out a different voltage.

Connecting a device for starting the engine with a dead battery provides for its connection to the power unit of the vehicle. This booster is only suitable for cars, since the power for its use must be about 12 V.

How to use the device?

Tips for using:

1. The process of operating the device for starting the engine with a dead battery involves throwing "crocodiles" on a dead battery, as a result of which an electric current will appear. The rules for using devices are different for each manufacturer. Therefore, before using it, you must carefully read the instructions, and only then take action.
2. Starting the device should not harm the battery. A single exposure to the battery should not exceed ten seconds.
3. Charging works only from the mains. Therefore, if a trouble happens on the road, only a cigarette lighter can help.
4. When using the booster, it is contraindicated to leave the device in the cold for a long time.

Exceptions are professional and semi-professional devices used by specialists from a car service.

Functional features of the device

If you decide to purchase a charger, the best option would be a device that contains a battery indicator indicator.

In the absence of this functionality, it will be difficult to use a starter for a car. How to choose it correctly? When buying a device for starting the engine with a dead battery, you need to pay attention to the following indicators:

• the device must have built-in zero discharge protection, since such a device will last much longer;
• the possibility of further charging;
• the power of the purchased device must be appropriate.

In order to avoid troubles, purchase equipment in specialized stores, which will be able to provide appropriate documentation on the quality and safety of the goods. Only in this way can you protect yourself and your transport.

How is the process carried out using the quick start device?

First you need to know that when connecting, you must observe the correct polarity.

The next step should be to control a certain voltage flow, which should be equal to 20 A. Depending on the battery, certain errors may be observed, but they should be minimal.

As the battery charges, the following conditions may appear:

• decrease in the viscosity of the electrolyte;
• drop in internal resistance;
• growth of the starter battery capacity.

If you turned on the battery starter, while the battery was fully charged, then the voltage at its terminals should quickly reach the required values \u200b\u200band it is not recommended to recharge it. In this case, you should turn your attention to the inclusion of the starter of the charger-starting device. If, after the measures taken, your vehicle still does not start, turn off the ignition and give it the opportunity to rest a little.

Practice shows that after this rest, the voltage on the battery will begin to increase and after the transition of an indicator determined by the technical characteristics, you can think about recharging. If the experiment takes a positive turn, disconnect the device from the battery. This action should not be ignored as running in parallel can overcharge the battery. This will negatively affect the performance of the vehicle.

be careful

After several ineffective attempts to wind up the engine, it is worth stopping any work in this direction and trying to find the problem of damage in another. Otherwise, you simply break the equipment and the starter, they will fail as a result of overload.

The second option for solving this problem will be to contact a car workshop equipped with modern technology, which in the shortest possible time will be able to diagnose and find the cause.

Actions for prolonged stagnation of the battery

If you are faced with the question of starting the battery after a long idle time, you must have the following knowledge:

1. We start the car after a long downtime, carefully and carefully.
2. What does the previous action mean? This means that a 3 month downtime will not affect the battery. And in the case of a longer downtime, you will have to carry out a certain set of measures, namely, checking vital components.

After that, you need to make the right choice of the charger.

The safest method is to use a quick start device. At the moment, this is the most recent technological achievement in the automotive world. This device is capable of passing through a fairly large flow of energy. This amount of energy is enough to fully charge the engine.

Terms of use

Keep in mind the following when working with such equipment. If you start the car after a long period of inactivity, you will have to remove the battery from the vehicle and carry out a full charge. It is important not to overcharge the battery. Otherwise, it will boil, which will not in the best way affect its functionality. In time, high-quality batteries are charged from 1 to 2 hours. The maximum voltage is 12.5-13 V. At a lower value, the car simply will not start, at a higher value, it will harm the battery.

Conclusion

Let's start, as usual, from afar ...

Electrical energy is really a flexible thing. The same amount of energy from the same source can always be presented in different forms - with high current and low voltage or high voltage but low current. Well, in any intermediate options, of course. You can take a battery with a nth voltage and maximum current and give these voltage and current to the load as it is. And you can connect an electronic converter to the battery and get a voltage hundreds or thousands of times higher than the original, but with a proportionally lower current. And it will be the same amount of energy (corrected for conversion loss, of course). In other words, it is easy to make another voltage and current from one voltage and current.

And here is an example that is close to motorists to understand (we warn the nerds and literalists about the conventions of numbers!) - we have, for example, a 12-volt battery, which in a charged state is capable of providing the current we need of 300 amperes. But it is half discharged - its voltage is 6 volts, and the potential current is barely half of the standard one. Such a battery is not suitable for starting the engine, although the "spherical-vacuum" energy reserve in it is still quite sufficient for our purposes.

Is there anything you can do? Yes. You can connect an electronic voltage converter to this battery, making 12 volts from 6 volts, and "pour" the rest of the energy into a 12-volt battery with half the capacity, filling it completely. And now it will already be quite suitable for starting the engine!

However, when we, with a sad complexion, open the hood of a car with a discharged battery that cannot be cranked by the starter, all these theoretical options with extracting the remainder of energy from a dead battery will be as meaningless for us as the weather on the Moon ... There is no second battery, where energy you can "overflow", there is no such converter and, most importantly, there is no time for this, because the batteries are not charged instantly ...

However, an energy storage device that can be charged almost instantly exists - this is a well-known capacitor!

Capacitor "launchers" - how are they arranged?

Rechargeable starters - they are "jump starters", they are "launchers", they are "boosters", have been known to Russian motorists for probably ten years. Gadgets, of course, are useful, but their main and common drawback, regardless of the manufacturer and model, is the impossibility of storing in the car in winter, because the lithium-ion batteries of the "launchers" are discharged and deteriorated from frost. Most people are too lazy to carry the device back and forth, and if you keep it at home, there is a risk that the "jump starter" will not be at hand just when it is vital ...

And some time ago, the so-called capacitor starters appeared on sale. The element base of these devices is based on modern supercapacitors or supercapacitors, characterized by high charge and discharge currents with relatively compact dimensions. An important feature of these devices is a long service life (at least 100 thousand charge-discharge cycles) and low dependence on ambient temperature. These gadgets can be left in the trunk of a car indefinitely - even in winter. Unlike "jump-starters" on lithium batteries, capacitor devices do not discharge in the cold, because they are not used for long-term energy storage. They are brought into combat readiness immediately before launch, being charged from the standard battery of the vehicle that has run low. You can safely keep such a device in the trunk all year round and not worry that it will not be able to help you because it was discharged in the summer or because its battery swelled and deteriorated from frost in winter.

So, capacitor starters, as the name implies, contain a battery of high-capacity supercapacitors and an electronic converter that makes a high voltage from the low voltage of a dead battery to charge the capacitor. Simplified, the filling of a capacitor "jump starter" looks like this:

To charge supercapacitors to a voltage of 12 volts, suitable for starting a motor, even an almost empty battery, which has run down to 10% of the remaining energy, is sufficient! In this case, the charging time of the capacitor "booster", of course, depends on the voltage and power of the power source, as well as the capacity of the capacitor banks themselves inside the device.

For example, a neighbor asked you to "light" his car - in this case, you connect the capacitor "launcher" to YOUR battery, which is fully charged, and it fills the capacitors in a few tens of seconds (40-60 seconds). Then you connect the device to the neighboring battery and start up its motor.

If you want to start the car from ITS OWN discharged battery, then the filling time of the capacitors may already be different - depending on the degree of battery discharge. From the battery, which no longer turns the starter, but still lights the lights on the dashboard, the "launcher" will be charged in 2-3 minutes. From the battery, from which the "tidy" is barely smoldering - in 5-7 minutes.

However, in any case, with a capacitor gadget, you become completely autonomous - you do not need to look for a "bro" who will light up or pull a ion ".

The capacitor starter is always with you and can constantly live in the trunk all year round, because it does not require attention and care at all and is indifferent to frost and heat in the range from -40 to +65.

True, there is a peculiarity! Which must be taken into account. A block of supercapacitors, even of a very large capacity, is not capable, like a battery, of doing dozens of engine starts in a row. One charge - one start: capacitor gadgets have such arithmetic. Then the cycle will have to be repeated.

BERKUT JSC-450C

JSC-450C is a typical representative of the class of capacitor launchers from the Berkut brand, which is well known to domestic motorists. The device is designed to start gasoline engines with 12-volt starters up to 4.5 liters in volume and diesel engines up to 3 liters. The number "450" \u200b\u200bin the name means the rated 450 amperes of output current.

"Launcher" is quite large, although lightweight. It is designed very laconically, with only a LED charging indicator, a start button and a diesel button on the body. The latter will not be needed if you have a gasoline engine - this key enables a special additional mode with preliminary heating of the glow plugs before turning on the starter. To charge the device, you can also use the built-in 12V connector through an adapter to the cigarette lighter socket, as well as through the MicroUSB connector, where the charging current should be 2 A at 5 V.

2 / 3

3 / 3

As already mentioned, a special advantage of capacitor launchers is their "frost resistance", which allows them to live peacefully in the trunk and not ask home to warm up. Checking! We freeze the device for a day at minus 17 degrees, remove it from the freezer and charge it. The cold did not affect the charge speed - the device took half a minute from a fully functional battery, and in two minutes from a half-discharged one.

We now connect the instrument to a 0.05 ohm coil load plug providing a load current of approximately 240 amps. "Launcher" of traditional design, running on a lithium-ion battery, a similar test recently, which is not surprising - lithium is not friendly with the cold, it is common knowledge. But the capacitor coped easily, quickly accepting the charge and giving it out powerfully, with a voltage drop of only one volt!

BERKUT JSC-600C

Another very interesting subtype of starting devices is hybrid jump starters. The hybrid is, according to the principle of operation, a purely capacitor "launcher", but in case the battery in the car is discharged to zero, and it is not possible to squeeze out even a drop of energy from it, the hybrid "jump starter" has its own built-in small lithium-ion battery ... From this backup battery, you can literally charge the hybrid supercapacitors within 3-5 minutes and start the engine. Moreover, when the backup battery is fully charged, the engine can be started up to 5 times.

In order for the built-in mini-battery to be always ready for use, you will have to monitor the state of its charge by connecting the device once every three months via the MicroUSB connector to a USB source of 5 V and 2 A. with decreasing temperature, its self-discharge rate increases. At the same time, it is possible to store the "hybrid" in the car in winter, which cannot be said about conventional lithium-polymer starting devices, whose storage temperature range is from 0 ° C to + 30 ° C. The difference is that in JSC-600C the battery is responsible for charging the supercapacitors, and not for starting the engine, so it does not require such a powerful current output.

BERKUT JSC-600C is just a hybrid capacitor starter. The gadget is slightly larger than the JSC-450C, although, like the younger model, it is not at all heavy. The device is clothed in a thick rubber shockproof "jacket", in addition to the "start" and "diesel" buttons, it has a button to turn on the built-in flashlight, and a blue backlit display shows the percentage of capacitors and built-in backup battery charge, as well as the voltage at the battery terminals and connection error.

Since the service life of lithium-ion batteries is much lower than capacitors, the manufacturer took care of the possibility of replacing the built-in battery in advance by equipping it with a separate storage compartment inside the case. This is how the built-in backup battery in the "hybrid" BERKUT JSC-600C looks like. It is a paired block of batteries of the popular size 18650 - if anything, this is easy to replace.

By the way, in the event of a complete battery discharge, the manufacturer recommends connecting capacitor devices INSTEAD OF a standard battery. In other words, first you need to remove the terminal from the standard battery using a 10 spanner wrench and connect directly to the terminal of the starting device, then you can start the engine. This is done so that the internal resistance of a heavily discharged battery does not interfere with starting the engine. After the engine starts, you need to turn off the device, return the terminal to the battery and tighten it well.

By the way, the Berkut capacitor launchers are equipped with powerful branded tactical suitcases. The weight of the person in the photo is 120 kilos, and the case didn't even creak!

Today, the high price for supercapacitors with high discharge currents does not allow them to be widely used in automotive technology and electronics, as it leads to their significant rise in price. But capacitor jump starters will definitely appeal to technically advanced car owners, who will be able to fully appreciate their advantages and will not panic from a specific application algorithm. For the most effective use of such devices, it is desirable to understand their principle of operation and the processes taking place in them. We are satisfied with the results of our tests and can safely recommend these devices for purchase.

Modern vehicles with installed equipment provide a decent level of comfort and safety on the road. However, many owners of such cars do not know how to act if everyday malfunctions are suddenly discovered. For example, they don't know how to start the car if the battery runs out at the most inopportune moment.

The battery can sit down for several reasons. Imagine the situation: you have not used the car for a while, and when you got behind the wheel again, you encountered an inoperative battery. A defective battery prevents the doors from being opened and the car starting. If you use a regular key together with an automatic key fob, there should be no problems when opening with a faulty battery. If the key has not been used for a long time, the larva could easily rust, and it will be impossible to insert the key there.

Don't be in a hurry to get upset. There are a number of proven methods that will help open the car and ensure the start of the battery without calling specialized services.

How to understand that the battery is dead

There are a number of signs that indicate battery problems. Most often, symptoms begin to appear prematurely, before the battery approaches the zero charge mark. If you diagnose the problem in a timely manner, you can avoid getting into an emergency situation.

In many cases, dead battery problems are easier to prevent.

The following symptoms of a discharged battery are distinguished:

• The alarm starts to work incorrectly. When you press a button on the key fob, the protection turns off very slowly, the doors do not open periodically, the central type locks simply do not work;
• The audio system in the car turns off immediately after the engine is turned off due to a too sharp voltage drop;
• Problems with the brightness of the light in the passenger compartment, a decrease in the brightness of the headlights while driving;
• During the start, the engine starts after a jerk of the starter, then the device freezes for a second, after which it starts working in standard mode. In case of problems with the battery, the engine always starts slower than with a working battery;
• During warming up, the speed indicators often jump. The problem stems from the fact that during this mode of operation, the car engine increases energy consumption from the battery, which is practically empty.

How to open a car with a discharged battery

There are several ways to open a car with a discharged alternator. The first method involves working under the car, so it is advisable to have with you not only an additional generator, from which the dead battery will be recharged, but also a jack, as well as two wires with a cross section of 2 centimeters and a length of about a meter. The sequence of actions in this case is as follows:

1. Using a jack, we lift the car;
2. We get to the engine after removing the protection;
3. We find the positive terminal and clamp the wire on it using the "crocodile" clip;
4. We connect the negative wire to the car body;
5. We connect the wires to a working battery. Make sure the terminals are connected correctly;
6. After connecting the alarm, open the car from the key fob;
7. We open the hood, take out the discharged battery and charge it.

There are several easier ways to open doors. When the glass at the front door was not fully raised, you can put a thin iron rod with a hook at the end into the resulting free space. With the help of a hook, we hook up the handle and carefully pull the entire structure up. If the handle opens to the side, we do the same manipulations, but we press on the handle, and do not pull it.

The following method is used extremely rarely. Using an ordinary hammer, the glass in the car from the driver's side is broken. It will not be superfluous to protect open areas of the body, so as not to get hurt by the resulting glass fragments.

To implement the next method, you will need a wooden wedge. The wedge is about 20 centimeters long and about 4 centimeters wide at the base. A meter-long metal rod should also be prepared. A wooden wedge is carefully inserted between the upper rear corner of the door and the pillar of the car and is gradually driven in with a fist until a gap of about 2-3 centimeters is formed. A metal rod is inserted into the slot, with the help of which the lock blocker turns.

Most often, a peg up to 20 centimeters long is used to open a jammed door, but it is not recommended to use a key in this case

Another method involves having a drill or screwdriver on hand. We select a suitable drill and cut out the lock cylinder. We add that after using this method, you will have to change the larvae in all the doors of the car.

The above methods are more suitable for domestic cars. Modern foreign cars are equipped with special anti-theft systems, for example, it is no longer possible to insert a wire between the glass and the seal.

How to open the door of a foreign car

In order to minimize the likelihood of a situation when the door has to be opened by emergency methods, it is worth periodically opening the locks with a regular key. This will prevent the lock from rusting, and if the automatic switches off, you can always open the car manually.

In foreign cars, access to the salon occurs by a small bend in the door area. To implement this method, you will need a long wire, a screwdriver and a piece of any fabric. It is advisable to make a bend in the area of \u200b\u200bthe car rack - the cloth is initially pushed into it, after which a screwdriver is inserted (a rag will help to avoid damage to the car surface). The door is gradually bent with the tool until the wire crawls through the gap.

The driver's door is bent with a screwdriver, and then the wire is inserted there

Ways to "reanimate" a dead battery

Even an expensive and high-quality battery after a while starts to lose charge by itself. Basically, the following factors provoke the problem:

• The battery has been serving for more than 4-5 years, and over time, the available charge decreases;
• For some reason, the battery is not recharged during the trip;
• There are places with current leakage in the car network;
• When the engine was turned off, the headlights or audio system were left on;
• Critical exposure to extreme temperatures.

It is possible to start the car with a dead battery, so we will consider several ways to solve the problem.

With the help of acceleration from an external force

To start the car, it is enough to set it in motion. This can be done by:

• Acceleration up to 5 km / h when pushing;
• Ask another driver on the road to take your car in tow.

From the "pusher"

In this case, the acceleration of a car is gaining with the use of human power. This method is best used on a road with a slight incline to facilitate the task. Push only by the rear pillars or by the trunk of a vehicle, otherwise there is a high probability of serious injury. Only a car with a manual transmission can "start" in this way.

Starting a car "from a pusher" is quite popular in our country, but this method is only suitable for cars with manual transmission

After the car reaches a speed of 5-10 kilometers per hour, it is necessary to engage the gear and smoothly release the clutch.

By tug

For towing, you need a special cable with a length of at least 5 meters, as well as another vehicle on the move, which will act as a tug.

The vehicles are connected by a cable, after which the tug will accelerate your car to 10-15 km / h. When the specified speed is reached, 3rd gear is engaged and the clutch is smoothly released. If the car starts, you can disconnect the towing cable.

A tow rope should be in the trunk of every vehicle in case of emergencies

It is extremely important when starting the battery with the help of a tugboat to coordinate the actions of both drivers and to discuss the signs that will be given to each other while driving. Uncoordinated towing can result in serious damage to vehicles and create an emergency on the road.

"Lighting" from a donor car

This requires another auto-donor with a fully functional battery. The ignition of the 12-volt unit is carried out exclusively from a 12-volt donor. In case your battery has a voltage of 24 volts, you can use two donor 12 volt batteries, which will be connected in series.

The method includes the following steps:

1. The cars are parked next to each other, but do not touch.
2. At the donor car, the engine is turned off, at the second car, the wire is removed from the negative terminal. When carrying out work, polarity is respected, if this rule is violated, there is a high probability of failure of all electronics in both cars.
3. The positive terminals of the batteries are connected to each other, then the minus is connected to the donor and only after that to the car, which needs resuscitation.
4. The donor car starts up for 4-5 minutes and is left in the switched on state.
5. Then the second car starts up, it should work for 5-7 minutes.
6. The terminals are disconnected, but the car is left running for another 15-20 minutes to allow the battery to recharge.

Using a starter-charger

This method is the simplest and safest. A special device is connected to the network, the mode switch is set to the "start" position. The negative wire of the starter and charger is connected to the engine block in the vicinity of the starter, the positive wire to the positive terminal.

Depending on the model, the electrical diagram of the ROM may differ, but the principle of operation is always the same: the device is connected to the network and supplies current to the battery terminals

The ignition key turns in the car, if the car starts up, the starting-charger can be turned off.

Rope on the wheel

This method is useful if there is no tug car nearby and there is no one to push your transport.
In order to start a car in this way, you need a rope (about 5-6 meters in length) and a jack. With the help of a jack, it is necessary to make sure that the drive wheel is in a raised state from the ground. The rope is tightly wound around the wheel, after which the ignition and transmission are switched on. For the car to start, it is necessary to pull strongly at the end of the rope.

A bottle of wine

The most extraordinary way that really works. It will help to start the car in remote conditions, when there is only wine at hand.

It is necessary to open the wine and pour a glass of the drink directly into the battery. As a result, the alcoholic beverage will provoke an oxidative reaction, and the battery will begin to produce a current that is enough to start the car.

The wine method is only suitable for extreme cases, after such a start, the battery will have to be replaced with a new one.

Unfortunately, starting the battery with wine is only possible once.

How to start a battery on automatic transmission

To start a car with an “automatic”, methods with lighting from another battery are suitable, as well as the option with connecting the battery to the ROM. You can also try to lower the battery in a warm bath or simply replace it with a new one if you have one at hand.

The use of external force will not help to start a car equipped with an automatic transmission

Have you tried all the methods but got no result? Try to warm up the vehicle in a warm box.

Longer battery life

10 tips will help not only increase the battery life in a car, but also avoid emergency situations that are associated with the discharge of this unit in a vehicle:

1. If the battery will not be used for a long time, be sure to charge it;
2. The electrolyte should be poured to such a level that the plates are not exposed;
3. Full battery discharge is the main reason for shortening battery life;
4. Watch the tension of the alternator belt, and if loose, replace it immediately;
5. Make sure that there are no leaks in the car's electrical network;
6. Before leaving the car, be sure to turn off all electrical appliances;
7. In winter frosts, take the battery home at night;
8. Do not allow the battery wires to oxidize;
9. It is better not to leave the battery in a discharged state in winter;
10. In the winter season, it is advisable to use special covers for the battery, which will help prevent discharge.

Remember that it is much easier to control the battery charge and replace a worn out battery in a timely manner than to face emergency situations later, start and open a car using improvised methods.

Low temperatures sometimes bring unpleasant surprises even for those who regularly change the battery in their car. If it is -25 ° C or less outside, a fully functional battery loses up to half of its capacity overnight: the electrolyte thickens, the course of chemical reactions slows down and the battery can no longer give up all the accumulated energy.

Riding in the city cycle with the heater on, heated mirrors and seats on also does not help to properly charge the battery, not to mention the fact that you can simply forget to turn off parking lights or other devices in the parking lot.

A discharged battery will be emitted by the sticky noises and clicks of the starter when you try to start the engine, as well as the dim glow of the indicators on the dashboard, which becomes even weaker when the key is turned.

If the battery does not show signs of life, do not panic right away. There are no hopeless situations. There are at least four ways to wake up even with a dead battery.

How to start a car using a donor battery

The universal and most correct way of resuscitation. It is deservedly the most popular among drivers.

What is needed

• A donor car with a working battery.
• Starting wires with "crocodiles".

Unless trouble catches you in a deep forest, there should be no problems with the donor machine. But with a set of starting wires it is more difficult: if you do not carry one in the trunk, you can only hope that the driver who came to your aid will be more prudent.

What do we have to do

In order to successfully start a car with a planted battery and not harm the donor car, it is important to follow the correct sequence of actions:

1. Place the cars as close to each other as possible: bumper to bumper or bumper to fender depending on the location of the batteries.
2. Switch off the donor engine and be sure to turn off the ignition so as not to burn the electronics.
3. Connect the red jump lead to the positive terminals of both batteries, starting with the good one.
4. Connect one end of the black wire to the cylinder block or other metal part of the engine of your car, away from the elements of the fuel system, and the other to the negative terminal of the donor battery.
5. Try to start your car with no more than 2-3 attempts.
6. After the engine starts, let it run for a couple of minutes and disconnect the wires in reverse order.

Do not try to light a car with an engine capacity of more than two liters from a small car, especially a diesel one. The capacity of the donor battery must be greater than or equal to the capacity of the battery to be reanimated.

How to start a car from a tug or a pusher

The classic, one might say, old-fashioned method, when the engine is started by accelerating the car and switching on the gear. The injection engine can be started in this way only if the battery is not fully seated and its charge is sufficient for the fuel pump to pump fuel from the tank into the system.

The method is suitable exclusively for cars with a manual transmission.

What is needed

• Tow rope.
• Other serviceable car or assistants.

Even not in the most crowded place you can find, if not another car, then at least a couple of caring volunteers who are ready to push your car. Well, the cable should always be in the trunk.

What do we have to do

The method is extremely simple and does not require any special skills, except for coordination of actions and conditioned signals with all participants in the process.

1. Connect both vehicles with a tow rope.
2. Switch on the ignition on your car, depress the clutch and shift into third gear without releasing the clutch pedal.
3. Give a command to the driver of the towing car to start moving.
4. After accelerating to 10–20 km / h, smoothly release the clutch.
5. When the engine starts, depress the clutch again and signal to the other driver.

Do not rush to shift to neutral and let the engine run with the clutch depressed, otherwise, due to the cold oil in the transmission, it may stall right there. Remember this also in the event that strong volunteers will accelerate the car.

How to start a car with a rope

A rather complicated method, which nevertheless will help out if there is no one to expect help.

Suitable only for cars with manual transmission.

What is needed

• Jack.
• Towing cable or rope.

Every driver has a jack in the car. There should be a tow rope too. If it is not at hand, any rope at least 2-3 meters long will do.

What do we have to do

1. Set the parking brake and place stones or other supports under the wheels.
2. Jack up the machine so that one of the drive wheels is in the air.
3. Switch on the ignition and third gear.
4. Wrap a few turns of the rope or rope tightly around the wheel and pull sharply (you can run to the side).
5. If you cannot start the engine the first time, repeat the procedure.
6. When the engine is running, shift into neutral and lower the machine by removing the jack.

Never tie the cable to the disc or wind it around your hand. Otherwise, after starting the engine, there is a risk of serious injury if the cable winds around the rotating wheel.

How to start a car using the starter and charger

Starting-chargers, or so-called boosters, are the most technologically advanced method of starting a car with a discharged battery. Thanks to lithium-iron-phosphate batteries, these miniatures are capable of delivering colossal currents even with a small capacity.

Suitable for injection, carburetor and diesel cars with any type of transmission.

What is needed

• Booster.

The advantage of starters and chargers is that they are completely autonomous. Apart from the booster itself, nothing else is needed to start the car. The downside is the relatively high price of the gadgets.

What do we have to do

Each booster comes with detailed instructions, but the general principle of operation is the same.

1. Turn off the ignition in the car.
2. Connect the "crocodiles" of the booster to the battery terminals, observing the polarity.
3. Start a car.

Cars with an engine capacity of up to two liters, boosters start without any problems even in severe frost and with a completely discharged battery. Difficulties can only be with engines with a volume of more than two liters, especially with diesel ones.

How to prevent discharge

1. In order not to get into unpleasant situations, you need to monitor the condition of the battery and change it in a timely manner, without waiting for a complete failure.
2. Always engage the clutch when starting the engine. This saves the starter from having to rotate the gearbox gears in the congealed transmission oil and makes the process easier.
3. If you have an important trip, you can remove the battery from the car and take it home overnight. This will give you a better chance of starting the engine in the morning.
4. And, of course, do not forget to turn off the dimensions and other devices, leaving the car in the parking lot.

Tell us in the comments if you ever started a car with a discharged battery, and if so, which method did you use.

The battery in vehicles is an auxiliary source of energy. However, it is impossible to start without an electrical impulse with certain parameters. You can determine the performance of the battery by how the car starts. A good battery starts up quickly and quietly. The harder the car starts up, the less charge in the energy source. Let's figure out the reasons why the battery in the car can run out.

The device of lead acid batteries is identical. The body contains 6 elements - cans, consisting of lead plates with opposite charges and an electrolyte - a sulfuric acid solution. An electrochemical reaction takes place in each element independently. The connection diagram to the battery is consistent, the total charge is removed from two terminals - positive and negative. In order to generate enough energy, you need:

• all 6 cans must be in working order, have an electrolyte of the required density and level;
• there should be no damage in the battery case;
• the terminals are clean, no oxidation of the pins occurs;
• there is no internal closure of elements;
• no precipitation of PbSO4-sulfation is observed.

There are hybrid and low-maintenance batteries. They measure the electrolyte level in each jar through the lid, adjust the level and density by adding distilled water. Leakage can be due to splashing through covers or cracks. In maintenance-free batteries, lowering the charge to zero almost always renders the tool unusable.

The post is a lead from the battery. If the pin is oxidized, this is a signal that contact with electrolyte vapor is taking place. This is possible if the case is damaged or the battery is frequently overcharged. It is necessary to improve the sealing of the pins by using an additional seal or special grease. A short circuit is caused by bridges between active elements. The reasons may be:

• electrolyte with a large amount of sediment;
• destruction of separators;
• build-up on lead electrodes;
• delamination of gratings;
• ingress of dirt from the outside during other operations.

The deposition of undissolved lead sulfate crystals on surfaces occurs due to a violation of the operating mode. As a result, the battery sits down, during operation, there is a strong gas evolution and an increase in the charging voltage at the beginning.

When a good car battery runs out quickly

Battery - accessories, consumption and replenishment depends on the general condition of the equipment and the driver's vigilance. What to do if the battery runs out quickly, does not gain charge while driving? The reasons may be related to the operation of the generator. If during engine operation the generator does not recharge the battery, the problem is in the electrical. If a whistle is heard at the start - the belt is loose, it is easy to tighten it.

An inexperienced driver himself can make mistakes when a new battery runs out quickly:

• With a long idle time, they forgot to turn off the headlights, lighting, music - overnight all signs of a dead battery will appear in the car.
• The short shoulder of the trip will not allow you to recharge. The device left overnight has insufficient energy resources. In the morning, it turns out that the battery on the car sat down and does not turn the starter.
• There is no regard for the additional power supply. As a result, time was lost to solve the problem without losses, and if the automatic battery runs down, it will have to be disposed of.

If the equipment is used improperly, the car battery can run out in a short time, in a week, in a day, in a day. An attentive driver will identify the problem by whistling, tapping, squeaking, without bringing the car to an emergency stop.

How to tell a beginner when the battery is dead

Nothing in a car breaks down without preliminary signs, except for a puncture of the rubber. Some abnormalities in the operation of electrical equipment appear long before the battery on the car runs out. But they are connected precisely with the battery:

• A sign that the battery is dead will be the too long reaction of the alarm after pressing the button on the key fob. The remote control of the machine is powered by the battery. At the same time, you will notice that the central locking is sticking, the doors do not open well.
• The radio tape recorder itself turns off shortly after the engine stops - a strong voltage drop in the network - sat down on the car battery.
• The brightness of the interior lighting and headlights has decreased - the reason is that most of the energy from the generator is directed to feed the car battery, which sits down.
• The start is intermittent, the starter jerks with a pause, the engine starts slowly, with effort.
• When the engine warms up, the rpm is unstable, since the battery does not help.

There are other signs associated with a failure in the computer or climate, the generator gives more energy to ensure the life of the battery. The problem with insufficient battery performance will not go away by itself, it will get worse. At the end it will be impossible to start the engine or get into the salon. If the battery is completely dead and belongs to unattended, it cannot be restored, it will have to be replaced.

If the car battery has run out, the owner of the vehicle will determine this by the following criteria:

• when turning the key in the lock, stringy sounds are heard;
• the dashboard is dim or the indicators do not turn on;
• crackles under the hood.

How to start a car with a dead battery

After a long idle period or on a cold morning, it turns out that the battery on the car is dead, what should I do? How to start a car with a gun? How to get to the salon?

So, you cannot open the door remotely. You need to use a key, but often the lock cylinder will not turn. To get into the passenger compartment, charge a dead battery with another portable battery. The most difficult thing is to get close to the positive terminal of the battery. A special pillow will help, which is pushed into the gap and inflated with a pear. By attaching the copper wire to the positive terminal, it is connected to an external power source. Minus from an external source is connected to the machine body. The battery will be replenished, the door will open from the key fob. Now you need to start the car. There are other ways as well. We suggest watching a video on how to open the car with a discharged battery.

You can start the car engine if the battery is low and you entered the passenger compartment in different ways. What to do depends on the circumstances.

1. For all types of cars, the use of a starter-charger is suitable. With its help, a dead car battery is started.
2. The method of "lighting" from the donor's car will help if the battery runs out, but it can be reanimated.
3. Using 30% more "boost current" than standard values, the battery can be recharged in 20 minutes without removing. But for models with an on-board computer, the ground must be disconnected. The method is barbaric, the battery life is shortened.
4. What to do with a dead battery if the car has stalled far from civilization? It remains to use a "curve starter", for this in the trunk there should be 5-6 meters of rope, slings and a jack. It is necessary to lift in front of the jack and spin the wheel with a wound rope.
5. The "pusher" method is known to all motorists.

How to "light" a dead battery?

The most common way to reanimate a car, if the car battery runs out for any reason, is to use the help of a "donor". It is essential that assistance is provided using a good battery of equal voltage. Two cars are installed side by side, but without touching. Connection operations are carried out with the assistant's motor turned off. On a discharged battery, remove the negative terminal. plus terminals are connected with a cigarette lighter wire with a cross section of at least 16 squares. The minus is connected first to the donor, then to the diseased car. The donor turns on the motor for 5-6 minutes, recharges the battery that has sat down. After that, the acceptor is started for the same time. After that, the terminals are disconnected and the battery is allowed to charge, idling for 15 to 20 minutes. A completely dead, disposable battery cannot be restored in this way. You will need to buy a new one.

Reasons why the battery is constantly low

Sometimes it happens that the driver observes the operating conditions, during the maintenance, and the new battery runs out. The reasons need to be looked for in a comprehensive manner, while it is better to contact the service station.

Why does a new car battery run out quickly? If your car is equipped with a computer, air conditioning, music, the generator cannot power the electronics with multiple ECUs, and the battery helps with its own energy. During movement, recharging the battery is not enough, during the idle period it is not. This is one of the reasons why the new battery is dead.

It happens that the service equipment is powered from the battery incorrectly, so the battery began to drain quickly. You can check how much the signaling and blocking systems consume energy during downtime with a tester. If the value is greater than 0.05 A, it is necessary to look for a leak in the on-board network. Often the reasons why a new battery has sat down is an incorrectly installed alarm or radio tape recorder.

If the battery is dead and won't charge

If the battery cannot be charged, there are three reasons:

• there is no charge from the generator when the engine is running;
• the battery has deteriorated, has lost its ability to recover;
• charging station does not work.

If the red battery light is on while the engine is running - charging does not work for two reasons - either the generator does not work, or the battery is discharged to zero. If the generator is faulty, the voltmeter readings are unchanged and go beyond 14.6 V. When the voltage at the battery terminals is 11 V, the battery is considered completely discharged. If the battery is not being charged from the station, this can be seen from the stationary voltage and current arrows on the dial. A completely discharged calcium battery cannot be recovered. Others can be tried to reanimate.

Why the battery sat down in the cold

Car operation in winter is associated with additional difficulties. For the battery, frosts below -15 0 С are the reason for a decrease in capacity by 1% when the electrolyte cools down by 1 degree. Prolonged downtime of the car will be the reason why the new battery sat down in the cold. What to do? If it is not possible to put the car in a warm garage, you need to insulate the battery so that it does not sit down too much during idle time.

It is necessary to put the car in a long-term parking, making sure that the battery is fully charged. In the cold morning, more starting current will be required to start frozen systems with thickened grease. In cold weather, the battery often sits down if it does not hold a charge well or is left at 50% charge for many hours of parking.

If your battery runs out for example a week after the mains charging, check the on-board power system for leaks. In winter, it is better to install a special high-capacity battery. Short trips with frequent engine starts are detrimental to the state of the energy source. In moments of movement, the generator does not have time to restore the battery charge.
