If you need to remove the battery, you need to know how to properly remove the car battery, observing the sequence and a number of important points. Of course, many simply take the car to the service, where specialists will do everything, but sometimes this is not only inconvenient, but also unprofitable. If you want to clean the pallet, charge the battery or replace, or do something else, but you cannot do without removing the battery, then read this article to the end.

There are a lot of chargers (chargers). Among them there are both home-made devices and those purchased in specialized stores. It must be remembered that the temperature of the electrolyte increases during charging, it begins to boil, and poisonous gases are released. Therefore, it is recommended not only to thoroughly ventilate the room, but also be sure to unscrew the lids of the cans. If the charger charges the battery very quickly, then this is not good. This indicates an irregular current supply, which is detrimental to our battery. On average, 30 minutes of charging equals 70 hours of use.

Preparatory work before installing the battery

The installation process itself is performed in the reverse order from removal, however, you need to prepare the seat and the battery itself. The tray on which the battery is installed must be cleaned of oxide, it is often heavily soiled, so it can be brushed with a metal brush and wiped with a clean cloth. The same applies to the rubber lining, it is advisable to rinse and wipe it, and then install it on a pallet.

Sometimes motorists find that the battery seat has corroded and is therefore not reliable. In this case, a replacement is recommended. It is advisable to pre-treat the battery, wipe it, wash it if possible, but you need to make sure that water does not get onto the terminals and into the battery banks. It is advisable to rub the wires with sandpaper, since they oxidize at the points of contact, due to which the current permeability deteriorates. At this point, all the preparatory work can be considered completed and proceed to the direct installation.

Learning to install the battery correctly

Place the rubber lining on the cleaned pallet. Next, we put the battery, it should be installed approximately in the center. This is extremely important, since on a large pit or bump, the fastening may loosen and the battery will be damaged on the impeller, but this applies only to cars of the VAZ family.

After we have installed the battery in its original position, we fix the clamping bar. Above, we have already said that we have two poles for batteries: plus and minus. You need to connect plus to plus, and minus, respectively, to minus. If you do not follow this simple rule, then the device will quickly fail. In addition, a short circuit will occur, which can ruin almost the entire network, starting from the dimensions and ending with the fuses responsible for the windshield wipers, etc. The wires connected to the battery terminals should not be under tension, as they can break during driving , and this is not good.

What everyone should remember when working with a battery

Under no circumstances should work be carried out with the engine running. Firstly, it is dangerous to health, and secondly, you can damage wires, batteries and fuel hoses, and much more. There is also a risk of electric shock while the generator is running. By following the instructions above, you should have a clear idea of \u200b\u200bhow to properly remove the battery. The sequence looks like this:

• removal of the "minus";
• weakening of the "plus";
• removal of the clamping plate (battery fastening);
• take out the battery.

If you did not find the battery in the engine compartment, then most likely it is located directly in the trunk or under the rear seat in the car. In this case, the withdrawal sequence is exactly the same and does not differ from the above.

Conclusion

In conclusion, I would like to say that the battery can serve for more than 5 years, but for this it needs constant care. Maintaining charge as well as cleanliness are fundamental factors. In no case should you overcharge. As for the removal and installation, after you have done this operation several times, you will not have a question: how to remove the battery from the car, etc. The main thing is to follow the instructions, take precautions and do not work in a hurry.

A battery is required to start a vehicle's engine. Its serviceability makes the mechanism work stable. The downtime of the car, which often occurs in winter, does not have the best effect on the condition of the battery. Storage rules in the cold season will help keep it working.

• dry-charged - designed for self-filling with electrolyte, after which the battery is ready for use without requiring additional charge;
• filled with electrolyte during production (unattended) - equipped with special elements that absorb moisture and prevent electrolyte from flowing out of the case;
• gel - the electrolyte is contained in a thickened state (they are resistant to heavy loads, fast charge and endurance to deep discharges);
• motorcycle - electrolyte is absorbed into the absorbed fiberglass.

Is storage required in winter?

Some car enthusiasts remove the battery at night and take it home. Is there a need for this or is it a relic of the past? Only one thing can be said for sure - there is no point in performing such a procedure every day. In winter, if the frost does not drop to 30 degrees, and the car is regularly used, it is enough to remove the battery twice a month to recharge it.

It is also possible that the battery is already old, so it cannot withstand an overnight stay outside in winter. In this case, you also need to take care of bringing it into the warmth. Although in such a situation, it is better to purchase a new battery, since it is always troublesome to remove it and bring it home.

Owners who rarely use the car in winter should take care to keep the battery warm. Even if it is completely serviceable, it will sit down in idle mode in literally two weeks. Bring the battery to a warm place at night if severe frosts are expected. In this case, you shouldn't take risks and leave the device in the car, otherwise it may simply not start in the morning. If the car is not used at all in winter, the battery is removed and stored separately from it during the entire cold season.

Preparatory work

To prevent the battery from discharging during idle time, it is necessary to disconnect one terminal from it. In this case, the loss of charge will be, but insignificant. However, the best option would be to store the battery in a warm room during the winter. When the battery is removed, the car will painlessly perceive the lack of voltage. You can even say that it will benefit him.

When removing the battery, first disconnect the negative and then the positive terminal, which avoids a short circuit

Dry battery

Dry battery preparation is performed in the following way:

1. The cans' caps are unscrewed, and the electrolyte level is measured through the holes using a glass tube. Its quantity can also be estimated by the marks that are present inside each jar. If the battery is transparent, the electrolyte level is visible from the outside. In this case, the marks are usually made on the battery case. The electrolyte level should be within 12 mm. If the value obtained is less, you need to top up with distilled water.
2. The density of the electrolyte is checked, its indicator should be 1.25–1.29, but not differ by more than 0.01. If this condition is not met, you need to achieve an average value. When the density is higher, distilled water is added, at a lower value, battery acid is poured.
3. The surface of the battery is washed with a baking soda solution to neutralize the acid, and the terminals are treated with conductive grease.
4. The surface of the case is checked for damage.
5. The battery is charged, wrapped in plastic wrap or cloth to avoid possible external influences, and placed in the storage space.

If it is not possible to charge the serviced battery, fill it with a boric acid solution (5%). You will need to perform actions in the following sequence:

1. The battery is fully charged.
2. The electrolyte solution is drained within 15 minutes.
3. Distilled water is poured inside, the battery is thoroughly washed 2 times.
4. Boric acid solution is poured.

Filled with electrolyte

To prepare the device for storage, the following sequence of actions is performed:

1. The state of charge of the device is assessed - if it is low, then it is increased using an external charger.
2. The battery is removed from the machine, the terminals are disconnected in the correct sequence.
3. The body of the device is cleaned from traces of dirt.
4. The battery is wrapped in a cloth or plastic wrap and sent to storage.

Gel

These batteries are maintenance-free devices. In addition, they are resistant to atmospheric and other external influences. To prepare your device for winter storage, you must:

1. Charge the battery if it is low. It should be remembered that gel batteries are very demanding on voltage. During the charging process, it should remain unchanged, not exceed 14.4 V.
2. Remove the device from the vehicle.
3. Allocate storage space for the battery and place it in any position.

The gel battery can work even with a damaged case, but it still does not hurt to check it.

For motorcycle

Before sending a motorcycle battery for "wintering", it must be prepared:

1. The device is removed from the motorcycle.
2. The battery heats up at room temperature and is fully charged. It is important to pay attention to which electrochemical system is used in it. Modern motorcycles use lithium-iron or lithium-copper batteries. It is not recommended to charge them yourself. Given that devices of this type have a lower capacity than car batteries, a special charger is used in this case.
3. The battery is examined for damage and sent to a dry, dark place for storage.

Home storage rules

There are several rules that must be followed to ensure the complete safety of the battery. Each type of battery has its own nuances and storage characteristics.

Do not place batteries near hygroscopic materials, as acid fumes can be damaging to them.

The storage area should be dark, dry and well-ventilated. The optimum temperature is 0˚С. During storage, the battery must not come into contact with textiles and other products. In addition, you need to protect the battery from direct sunlight, as they can destroy its coating, which will lead to the loss of its original properties. Do not forget to check the state of its charge every month in order to increase it if necessary.

The serviced battery is stored vertically. Its plugs are tightly wrapped so that moisture does not get inside. The instrument case must be dry and sealed. When storing such a battery, it is necessary to maintain a distance of at least 1 meter from heating devices. The plugs should be checked periodically - if they have come off, they will need to be tightened again, after which the battery can be installed in its original place. It is advisable to store the device on a stand.

Maintenance-free

Storage requirements for a battery filled with electrolyte practically do not differ from the conditions in the case of dry-charged batteries. True, you don't have to check how tight the plugs are. The device is also placed in a dry room with low humidity and good ventilation, installed vertically. It is recommended to avoid sudden changes in temperature as this may negatively affect the performance of the battery later. If the battery has been used for less than a year, it does not always require additional charging. Otherwise, the device is usually charged every three months.

Gel

Gel batteries require recharging much less frequently than other types of batteries. It is enough to do this once a season, sometimes more often. The main thing is not to interrupt the process, but to bring it to the end. For example, if you stop at 70%, the device will not be able to reach the required capacity the next time. Therefore, a fully charged battery must be delivered to the storage room. If it is working properly, most likely, you will not have to carry out any manipulations with it. Although, periodic checking will not hurt. Gel batteries can withstand temperatures from -35˚C to + 60˚C, they can be installed in any position. The room does not require additional ventilation.

Motorcycle

If the motorcycle is parked in a dry, heated garage with a temperature of at least 15˚C, the battery does not need to be removed. It is enough to limit yourself to disconnecting the negative terminal so that the device does not self-discharge. If the conditions are not suitable for storing the battery, it will have to be removed and taken to a warmer place. During the winter, you will need to charge 3-4 times.

Restoration of working condition

At the end of winter, the battery should be prepared for use. First, a solution poured in the fall is drained from it. It should be noted that this must be done slowly, at the same pace at which it was flooded. It takes about 20 minutes to drain the acid. Then the device is rinsed from the inside with distilled water several times. It is advisable to let it sit in the batteries for 10 minutes to get the best effect. When the battery is thoroughly washed, electrolyte is poured into it and left for 40 minutes. This is necessary to check that its density has remained unchanged. Otherwise, you will need to correct this indicator, focusing on the marks.

After completing these steps, the device is completely ready for use, it can be installed in a vehicle. The terminals are connected upside-down as compared to removing the battery.

If you adhere to the established rules for storing the battery and use it correctly, it will last a very long time.

Removing the battery from the car is a task that every car owner faces. This may be required for replacement of the battery itself, its maintenance or temporary storage, for example, in winter in a warm room.

To quickly remove and then install the battery is quite within the power of an ordinary motorist, and for this, as a rule, special skills are not required. You just need to know a few rules and adhere to a certain order of actions.

What the wrong shutdown order can lead to

Errors and negligence when removing the battery can lead to both failure of the battery itself and damage to the car electronics. If a damaged battery can be replaced with a new one without great expense, then damage to the on-board computer as a result of a short circuit can be extremely costly.

How to properly remove the battery from the car

To properly remove the battery, you must follow the exact procedure.

Preparation for work

First, if you suddenly do not know yet, find out exactly where the battery is located in your car. In a modern car, the battery can be located in various (sometimes unexpected) places: in the trunk floor niche, under the rear seat, under the front seat, in the floor under the passenger's feet.

If, after opening the hood, you did not find a battery there, then look into the trunk and lift the floor panel - if it is not there, then Google will help you, as they say.

Further, if the battery is closed with a cover, remove it. Use a brush (not a metal one !!) to brush off accumulated dust and dirt. Find out which bolts are used to tighten the battery terminals and prepare the appropriate wrenches or caps (in most cases they are 10 or 13 mm in size).

The battery will be secured in its compartment. Inspect and figure out how to remove the mount and what tools are required for this.

What conditions must be met

Before unscrewing and removing the terminals from the battery, you need to:

• turn off the ignition of the car (it is better to remove the ignition key and put it in your pocket);

• turn off all working electrical appliances in the car (light, radio, headlights and other things that can function when the ignition key is pulled out). This is necessary to ensure that all electronics connected to the ignition are turned off;

• close all windows in the car, carefully close all doors and trunk (if your battery is in the trunk, then, accordingly, the hood);

• if your car is equipped with a power switch, turn it off.

Some car alarms have a habit of automatically blocking all doors in the event of a power cut to the car. It's good if at such a moment, the ignition key is in your pocket, and not inside the car.

If you have available the original manual for your car, then check: there may be instructions on what and how to do exactly in your car before dismantling the battery.

When all preparations are completed, you can start removing it.

Which battery terminal to remove first

Remember: the negative terminal of the battery is always removed first! You can determine where your battery has "plus" and where "minus" is by the color of the wires (plus is always red) or by the "+" and "-" marks on the battery itself.

This requirement is valid for all types of cars: injection, carburetor, with alarm, immobilizer or without them.

Do not believe if you read somewhere or hear that it makes no difference which terminal to remove first: "plus" or "minus".

The negative contact of the battery is connected to the body of your car - "ground". By removing the terminal from the minus, you, respectively, disconnect the battery from the car body. In the future, if, when removing the positive terminal, a wrench accidentally jumps off or falls out and touches any metal part of the body or engine, nothing will happen. The circuit: "minus battery - car body" is broken and a short circuit will not happen.

If you start to remove the positive terminal from the battery first and accidentally touch the metal part of the car body or engine with the key, a short circuit will occur, as a result of which, due to a strong current surge, even disconnected electronic devices in the car may be damaged.

Remember: a modern car has electronic components that NEVER turn off and remain energized at all times. They are the ones that are most often damaged in the event of a short circuit on the battery.

Longer contact of the "plus" of the battery with the case may even lead to a fire and a fire.

Procedure

• we loosen the fastening nut on the negative terminal, without unscrewing it completely;
• remove the terminal, set it aside and fix it;

The wires on the battery terminals are thick and elastic, so if they are not secured, the terminal may accidentally "jump" back onto the contact and cause a short circuit. For fastening, you can use wire or plastic fasteners.

Video - how to remove the battery from VW Polo Sedan:

If, when the terminal is removed, a spark jumps between it and the battery contact, this means that you have some device left on (or a malfunction of the car's wiring).

• we loosen the positive terminal fastening nut without unscrewing it completely;
• remove the positive terminal and also fix it away from the battery;
• remove the battery mount itself.

If the terminal is stuck

If one or both terminals are covered with a white coating, then before removing, they must first be cleaned with a brush (preferably a hard one, but not metal).

If the terminal "stuck" to the contact, you can use the WD 40 solvent. Treat the terminal with it, then gently pick it up from below with a large screwdriver and shake it a little. Then try twisting the terminal slightly from side to side until you can remove it.

Important: Avoid heavy efforts to avoid damaging the battery contacts.

How to remove correctly

With both terminals removed from the battery, release the battery from the retaining clip. Then the battery can be gently pulled out.

When removing the battery, try to keep it upright to avoid possible acid spillage. Despite the good tightness of modern batteries, this happens sometimes.

Features of removal from a car with an on-board computer

When removing or disconnecting the battery, the on-board computer loses all stored data received from the sensors in various modes of the vehicle.

Accordingly, after installing a new battery, you will need to test the car in different modes so that the computer will again write down and save the necessary parameters in memory. If this is not done, then the engine may malfunction.

Possible problems when removing the battery

With alarm

When the battery is disconnected, the alarm of your car may malfunction, namely:

• loss of one or more keys / remotes;
• failure of any additional alarm functions.

If this happens, then to restore the alarm, you will need to contact a specialized service.

It should be noted that malfunctions of the alarm when the battery is disconnected are quite rare.

With radio / radio

Before removing the battery, check if your car radio has a security PIN code. If so, make sure you have the correct PIN.

After disconnecting, all radio settings will be reset and when reconnecting you will need to re-enter the PIN code and tune the radio.

What not to do with the battery

• damage the case;

• damage the plugs of the filling holes and their necks;

• turn over or strongly tilt the battery;

• damage the contacts (for example, by trying to force the wrong-sized wire terminals onto them);

• store a discharged battery (especially at sub-zero temperatures);

• add acid.

Important: if you find that the electrolyte level in one or more jars is below normal, you can only top up with distilled water.

Precautionary measures

Remember - the battery is heavy enough. Hold it firmly and try to avoid impacts so as not to damage the battery case.

Important! If battery acid gets on your skin or clothing, wash the area with a solution of regular baking soda. In the absence of baking soda, simply rinse the acid sites with plenty of water.

If you have an alkaline battery, then if alkali gets on your clothes or skin, you will need to rinse them with an acid solution. (For this, ordinary citric acid or 10% vinegar solution is suitable).

It is best if you wear protective gloves when removing the battery.

When the battery is operating, hydrogen is released from it through the ventilation holes. This gas is extremely explosive. Even a small spark from an accidental short circuit can lead to an explosion under certain conditions. Therefore, it is best to work with the battery in a well-ventilated area or outdoors.

How to properly connect the battery to the car

Important! When installing the battery in its place, pay attention to the location of the "+" and "-" contacts, so as not to put the battery the other way around: with the positive contact to the negative wire.

There will not be much harm from this - the dimensions of the positive and negative contacts are different and it simply will not work to put the negative terminal on the positive contact without using a hammer.

If you have completely tightened the fixing nut on the positive terminal, and it still loosely hangs on the contact, check if you have put the positive terminal on the negative terminal.

The battery is installed in the reverse order:

• put the battery in its place in the car;
• secure it carefully with a standard mount;
• firmly put the positive terminal on the corresponding contact;
• tighten the fastening nut;
• then repeat the same with the negative terminal of the battery.

If the contacts or terminals are covered with a characteristic white coating, remove it with a hard brush (non-metallic). You can also use a special cleaner for electrical contacts.

Attention! Do not use hard metal brushes to clean the contacts or terminals! They leave deep scratches on the battery contacts and terminals, which causes them to heat up during operation.

Before tightening the fastening nuts, you can grease the terminals with special oil for electrical contacts or technical vaseline.

Easy care

Every time you look under the hood, do not forget to check the condition of the battery terminals and clean them if you see that they are covered with a white coating.

If you do not have time to remove the terminals, you can alternatively just cover them with baking soda and hold them for 15–20 minutes. Then wash off the resulting dirt with water.

In addition to the contacts and terminals, the ventilation holes must be cleaned regularly. They are located in the plugs of the middle battery cans.

Conclusion

Despite the simplicity of the work on disconnecting and replacing the battery, in some modern car models, stuffed to the brim with sophisticated electronics (for example, VW Faeton, the operation of components and mechanisms of which are controlled by 5 on-board computers and another, sixth, which controls the work of the first five), It is better not to change the battery at all on your own, but contact an official representative or service station.

The risk of failure of the on-board computer, resetting the settings or other troubles is very great, and further repair or adjustment will be much more expensive than the cost of replacing the battery.

I faced the situation of how to remove the battery quite recently. My wife and I returned from vacation, went to start the car, but the car wouldn't start, it didn't react at all to anything. I immediately began to suspect that the battery was dead. The neighbor turned out to have a charger. I don’t even remember which terminal I removed first - I didn’t even think about it. But everything worked out for me and nothing bad happened. I just charged the battery, put it in place and started driving.

Volodya

Recently I was on a hunt, forgot to turn off the headlights, stood for only 20 minutes and the whole car would not start. A passing car “lit a cigarette”, the wires were good, otherwise I would have to cuckle in the forest. I drove home normally. For a couple of days everything was normal, then frost hit and everything started, the car stopped. I tried to charge it myself, but it didn't work. I had to take it to a car service. There the masters did everything as it should be. Now at -30 starts without problems.

Paul

The battery turned 5 years old and one frosty morning -20 the autostart could not start the engine, even with the ignition key I could not breathe life into the car. And how wrong it is! In the evening, I removed the battery (according to the instructions) and set it to charge overnight.

Igor Vasilievich

I think you should not pay special attention to the spark that skips at the terminal when removed. The memory in the watch, receiver, etc., puts a little strain on the battery anyway, so there will always be a little spark.

Maria

The other day I ran into a problem how to remove the battery))) my husband left for another city, leaving me our car. And on the street just crushed under -30. The car was at auto start all night, and in the end Akum failed. I had to contact my neighbor - a sincere uncle turned out to be))) Everything ended well, the neighbor charged the house and put it back!)

Lucy

My car was left to "spend the night" with the side lights on. To go to work .. Well my brother helped out, changed the battery. She herself did not dare to take off)

Anya

I live in the north, we have very strong frosts (up to -50), so I suffer with the battery almost every day. But recently I was told that if the density of the electrolyte of the battery is slightly increased, then even in such frosts it is possible to start the car. And it turned out to be true! The car is difficult, but to start, I advise you to use this advice for operating batteries in cold weather)

Anton

With all the external simplicity of working with the battery, there are always a couple of important points. Yes, remove the negative terminal first. Remove and charge it before the cold weather begins. 4-5 years is the average battery life, after that you need to think about buying a new one. If in cold weather it stays on the car completely discharged for several days, then you can irrevocably lose it. For the winter, fill the engine with winter oil, it will be much easier. Well, when buying a new one, there are nuances with the location of the terminals and the size of the installation site, so it is better to go to the store by the car on which the battery will be installed.

Novel

I remember when I was young I did not attach importance to simple rules when removing a battery from a car. Therefore, its service life was reduced. In modern cars, designers place a battery (either in the trunk or in the floor). I prepare the keys and look at the connectors and gradually release the terminals (I start with a minus one). It must be remembered that the battery is heavy and if you do not hold it, it will be damaged and become unusable. I take out the battery slowly. If in the car the on-board computer will need to be tested after its installation, the electronics and there may be problems with the alarm. Nowadays, it's not a problem to contact a car service in case of a failure.

Kirill

Recently they forgot to turn off the light in the car and left the city for a few days. Upon arrival, an unpleasant surprise awaited us - the battery was discharged. It's good that there are no severe frosts on the street and we always have wires in the trunk. I had to ask a neighbor to light us, but it is worth remembering that you cannot light it if the electrolyte leaked out, the battery emits a strong smell or gets hot. Well, the discharge level was not critical and it saved us. Now I always check the light in the car. I don't want to get into such situations anymore.
And I would like to hear reviews about chargers, who uses which?

Nikolay

There is nothing complicated, just in some cars it is not always located in convenient places. But if you do not know all the nuances when removing and installing the battery, then this can lead to a malfunction of the electronics in the car. You need to stock up on keys of the appropriate size and turn off the ignition and remove the terminals from all devices. Again, the negative one is always removed first. Sometimes the terminal will become attached, I use a solvent. I always remember that after removing the battery, the on-board computer can freak out, so after installing a new battery I test the car in different modes and the computer saves all the parameters.

Dima

If the car is without an on-board computer, then you don't even need to be afraid. Just take a look once at how an experienced driver does it or watch a video on the Internet. The main thing in this matter is not to rush, to see where the battery is located, since in modern models it can be hidden in the most unexpected place. Open the niche and use the keys to unscrew the nuts and separate the terminals. Pull out the battery slowly so that it does not fall, otherwise it will crack and then you will have to buy a new one. But if there is an on-board computer in the car, then you need to be extremely careful and first of all turn off the ignition and all devices. Yes, and you need to remove it, starting from the negative terminal.

Peter

The most important and important thing when removing the battery is that the ignition key is in the driver's pocket, not in the ignition lock, not on the seat, not in the glove compartment, not on the panel. The central lock can block all doors and only a specialist with a "crowbar" can open them, or break the glass of the door. Such cases have been, are and will be. Otherwise, the procedure for removing the battery is simple and after a couple of attempts to remove and replace the battery, the young driver will remember the sequence of actions. Do not leave the battery unattended while charging, it is not the best option to leave it to charge in a closed garage overnight!

Kolya R.

In my opinion, it does not matter which terminal to remove first! How many cars there were in twenty years, and these are pretty decent and fresh Land Rover, Passat SS and Honda CR-V, there were no problems. But with battery mounts, especially with those that are screwed onto threaded connections, sometimes troubles happened. Sometimes they rusted hard, I had to use a rather rough locksmith tool, everything under the hood shines and is almost new, and around the battery the bare metal was covered with rust. One car mechanic said that due to the evaporation of acid from the battery cans, when the electrolyte is actively boiling during prolonged recharging.

Sergei

If you leave the car for a long-term parking, it is advisable to also remove the terminals, clean and seal them (wrap them with a plastic bag on an elastic band) until the next operation to preserve the battery charge. Be sure to remove the battery in winter to prevent freezing and complete destruction. Before moving the device indoors, be sure to check for cracks and smudges, it is advisable to clean the joints and put on the caps. We must not forget that a disconnected battery discharges over time - before use, it is necessary to check with a multimeter, if necessary, carry out full preventive measures.

Tatyana

The battery had to be removed only twice. The infection is heavy - they ate up to the workbench in the garage (my husband had no time). I had to shoot after I forgot to close the driver's door and the car stood in the garage for a week. The battery is completely empty. So I had to buy a new one. The old one did not hold the charge. When I put a new one, I forgot the key with the key fob in the car and when I began to connect the minus, the signal went off. The doors were locked and could not do anything. It's good that in the garage there was a signaling box, and in it there was a small key. I took off the rubber plug on the signaling and turned it off with this key. And then home for the second keychain. Now I never leave the keys in the car and the second key fob in the garage.

Vladislav

I believe that the battery should be removed at least twice a year, especially if it is in the engine compartment. The fact is that sand, old foliage and other dirt can accumulate under it, which practically does not dry out. Accordingly, a center of corrosion appears under the battery and the first holes in the body can begin there. The sequence of disconnecting from the on-board network is clear - the first terminal is negative, then positive. If the nuts are very acidic, or even worse on dead rusted - in no case do not use brute force - roll up the lead terminal, go to get a new battery. It is better to cut off the nut with a grinder.

Lyokha

The battery, like any device that can shock you, must be handled carefully and follow certain safety rules. If the vehicle is expected not to be used for a long time, the battery must be removed to avoid unpleasant situations.

George

The rule to disconnect the negative terminal of the battery first of all is a guarantee of the safety of the car from a short circuit. It is possible to break this rule if the car has a built-in power switch. Then it does not matter which wire to remove first - negative or positive. It is important to understand that the lead terminals of the battery are very soft and when installing the battery back, it does not require a lot of effort in tightening the wire ends, since deformation will occur and with subsequent similar procedures, a strong tightening will no longer work. The tips of the wires will twist and have poor contact.

I try once again not to climb to the nodes of the car, but there are several things that every driver (including women) must know and be able to do. Removing / installing the battery is just one of those. So far I had to shoot only once, but it was alarming. I've heard so much about high currents and the chance to "kill" the wiring and nodes susceptible to them! I had to call my neighbor and carry out this operation under his control. I remembered that I had to start with the negative terminal, gently shake the stuck contacts, in no case pull the wires and, most importantly, do not drop the heavy bandura on my feet. Well, the neighbor said)). In general, I did it.

Today, modern drivers do not have the same caring attitude towards batteries as they once did. The battery can be easily bought, they are always on sale, cars are used all year round, so few people remove the battery in winter, transferring it to a warm room. But you still have to remove the battery, mainly for recharging, or replacing the battery with a new one. Removal and installation work is really not difficult, on the one hand, but on the other hand, you need to know many of the features of this work. When I was young, I had to break the battery case, break the terminal on the battery, and if I had to often remove and install it, then break the negative terminal wire when removing from careless shooting. The appearance of an injector and an alarm on cars also had to study the features of replacing the battery. Once the alarm, during the battery replacement, tightly closed all the doors for me along with the ignition key. It's good that it happened in the yard of my house, I used a duplicate. In general, this work must be carried out more thoroughly.

Before removing the battery, you need to understand why? If the battery is out of order, then yes, we definitely remove it. Charge - you don't need to shoot. Repair work is necessary, it is necessary to de-energize, it is also not necessary to remove it, we just throw off the terminal. The battery closes access to other parts of the car, then you cannot do without removing it. So we see that it is not always necessary to shoot. But if you really have to, you must remember that if you have a foreign car, where there are electronics, secret police, on-board computer, removing the battery can be a problem. My neighbor in the garage changed the battery to a new one for AUDI 6, and so his brains flew in the car and had to be dragged by a tow truck to the service center. Therefore, to prevent this from happening, you must first connect an additional battery through the terminals or the cigarette lighter. Then everything is according to the article: we remove the minus, then the plus, then with the keys the bar holding the battery, then carefully take it out and put it on a flat surface. By the way, the battery weighs from 18 kg, so be careful.

From time to time and from technical oils, wires can lose their color; it is better to additionally mark them for polarity. By poking, you can get serious malfunctions. And the terminals are better to handle specials. spray before each removal and installation.

Problems when removing the battery can arise either due to the carelessness of the one who removes (from the wrong terminal), or if the battery has not been dismantled for a long time (the wires "stick"). Unfortunately, in my practice, I went through both problems. I still remember my first dismantling - it turned out to be painfully "funny" ...

I have an old 2108. So I have no problem removing the battery. But her husband had an Audi Q5 and he went on a business trip, and left the car in the garage with the doors open, and when he arrived he could not start it. He took off the battery and took it to charge. Then the car did not start. The service said that a brain failure due to a disconnected battery. They said before filming, it is necessary to connect another battery in parallel and only then disconnect the old one. And then I had to reflash my brains.

I removed the battery, put a new one and the glass lifters stopped working. What happened???

Yes, there is nothing special about removing the battery at all. The article was written correctly, just remove the first negative terminal and there will never be any problems, well, if you have power windows, then do not forget to close the windows to begin with, this is where all preparations end.

I always remove the battery if it is expected below -26 degrees. What's the point of playing the lottery: "will it start or not," when you can spend 2 minutes, remove the battery and take it home. The next morning, in any weather, the car will start guaranteed and you will go wherever you want. And without this it is far from a fact. We have severe winters in the Urals.

Many motorists in the winter give up their personal transport completely or go on trips on it much less often than usual. There are several reasons for this, and the main one is the presence of snow on the roads. At the same time, not all drivers care about preserving the battery in the winter, leaving it connected to the terminals as usual for weeks or months. Such negligence can lead to a complete discharge of the battery or its failure due to a short circuit of one of the cells. To prevent this from happening, you should take care of the question of how to store the battery in winter.

Should the battery be removed from the car in winter?

It is believed that car batteries need to be removed in winter in order to maintain their maximum charge. This statement is true, but not always, in some cases you can get by with less radical solutions.

In a "warm winter" (when the air temperature in the storage area of \u200b\u200bthe car does not drop below -10 degrees), in order to maintain the maximum charge of the battery and not bother with the transfer of the battery, it is recommended to reset one of the terminals of the on-board network from the power source. We recommend to avoid the risk of positive ground and short circuit of the on-board network. By removing one of the terminals from the car battery, it will be possible to greatly reduce the discharge process of the power source.

If the temperature in the place where the car is standing has dropped significantly below -10 degrees Celsius, you should think about moving the battery to a warmer room. At the same time, do not forget that the electronic systems settings will be reset from the vehicle's on-board network.

How to store the battery in winter?

The main thing that should be remembered in terms of battery safety in the winter is its position in space. Never store the battery vertically or "on its side". The power supply, dry-charged or filled with electrolyte, must always stand horizontally.

To store the battery in winter, you must choose the right place according to the following criteria:

• The battery case must not be exposed to direct sunlight. That is why, if there is a choice between storing the battery in the closet or on the balcony, it is better to give preference to the closet or any other "dark" room where the sun's rays do not fall. The danger when sunlight hits the battery during storage is that they can cause deformation of the case, and this will lead to malfunctions of the power source after connecting to the car;
• The temperature at the storage location of the battery must be above -5 degrees Celsius. You can leave the power source for the winter in a cellar or basement, where the temperature, if it drops below zero, is not much;
• The room should be well ventilated and free from high humidity. This is due to the fact that during self-discharge the battery emits a mixture of oxygen and hydrogen, which is explosive. During long-term storage, self-discharge is inevitable, and its value depends on the air temperature - the higher, the more.

Storing a battery with electrolyte requires not only the correct selection of the room, but also its preparation for "wintering". Many forums write that the electrolyte should be drained from the battery for its better preservation in winter - this is a lie. Moreover, before storing, it is necessary to check the electrolyte level in the battery. If it turns out to be low, then add distilled water to the battery, and then charge it as much as possible.

Attention: The battery can only be filled with distilled water. Never add tap water or acid, as this may cause unwanted reactions that will damage the power supply.

Long-term storage of the battery using boric acid without refueling

As a last resort, if it is not possible to regularly charge the battery to the limit values \u200b\u200bin winter, boric acid should be used to reduce self-discharge. Likewise, you can store a “spare” power supply for your car in your garage or apartment for months. To reduce self-discharge, a 5% boric acid solution is poured into the battery according to the following system:

Attention: Boric acid is susceptible to temperature changes, therefore, store a battery filled with it in a relatively warm place at temperatures above 0 degrees Celsius. However, remember to keep out of direct sunlight on the case of the power supply.

A "canned" battery can be stored for more than 15 years at a temperature of 0 degrees Celsius. In warmer conditions, its shelf life becomes shorter. Experts do not recommend storing the battery for more than 9 months without testing at temperatures above 20 degrees Celsius.

To restore the battery to working condition after storing it with boric acid, follow the instructions below:

1. Boric acid is slowly drained from the battery - within 15-20 minutes;
2. After complete draining of boric acid, the required volume of electrolyte is poured into the battery, which is a mixture of sulfuric acid with distilled water with a density of 1.83 g / cm 3. The electrolyte should be topped up at a temperature between 15 and 30 degrees Celsius;

After renewing the electrolyte in the battery, make sure that its density does not decrease. To do this, it is better to leave the battery for 40 minutes, and then measure the density of the electrolyte. If everything is in order, the battery can be installed on the car and be sure that at the most inopportune moment there will be no need
