Is it possible to charge the battery without removing the terminals and the battery. Storage of different types of batteries in the winter Why remove the battery for the winter

Removing the battery from the car is a task that every car owner faces. This may be required to replace the battery itself, maintain it or temporarily store it, for example, in winter in a warm room.

It is quite possible for an ordinary motorist to quickly remove and then install the battery, and this, as a rule, does not require special skills. You just need to know a few rules and follow a certain procedure.

What can the wrong shutdown order lead to?

Mistakes and negligence when removing the battery can lead to both the failure of the battery itself and damage to the car's 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 cost you extremely.

How to remove the battery from the car

To properly remove the battery, you must follow a certain procedure exactly.

Preparation for work

For starters, if you suddenly don't 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 niche of the trunk floor, under the rear seat, under the front seat, in the floor under the passenger's feet.

If opening the hood you didn’t find the battery there, then look in the trunk and lift the floor panel - if it’s not there, then Google will help you, as they say.

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

What conditions must be met

Before unscrewing and throwing off 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 (lights, radio, headlights and other things that can function when the ignition key is pulled out). This is necessary to ensure that all electronics tied to turning on the ignition are turned off;

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

• If your car is equipped with a mass switch, turn it off.

Some car alarms tend to automatically block all doors in the event of a power failure of the car. Well, if at such a moment, the ignition key is in your pocket, and not inside the car.

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

When all preparations are completed, you can begin to remove it.

Which battery terminal to remove first

Remember: always remove the negative battery terminal 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 or without alarm, immobilizer.

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

The negative terminal of the battery is connected to the body of your car - "ground". By removing the terminal from the minus, you, accordingly, 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 some metal part of the body or engine, nothing will happen. The circuit: “battery minus - 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 a metal part of the car body or engine with a key, a short circuit will occur, as a result of which, due to a strong current surge, even disconnected electronic devices in the car can be damaged.

Remember: in a modern car there are electronic blocks, which NEVER turn off and always remain energized. It is they who are damaged in the event of a short circuit on the battery most often.

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

Procedure

• loosen the fastening nut on the negative terminal without unscrewing it completely;
• remove the terminal, take it to the side and fix it;

The wires on the battery terminals are thick and elastic, so if they are not fixed, 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 the VW Polo Sedan:

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

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

If the terminal is stuck

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

If the terminal is “stuck” to the contact, you can use the WD 40 solvent. Treat the terminal with it, then carefully pry it from the bottom with a large screwdriver and shake it a little. Then try to slightly twist the terminal from side to side until you can remove it.

Important: avoid strong efforts so as not to damage the battery contacts.

How to take out

After both terminals are removed from the battery, release the battery from the holder holding it. The battery can then be carefully pulled out.

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

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

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

Accordingly, after installing a new battery, you will need to test the car in different modes so that the computer again records and stores 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, malfunctions of the alarm system of your car may occur, namely:

• loss of one or more keys/remote controls;
• 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 failures in the operation of the alarm when the battery is disconnected occur quite rarely.

With radio / radio

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

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

What not to do with the battery

• damage the hull

• 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 unsuitable wire terminals on them);

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

• add acid.

Important: if it is found that in one or more banks the electrolyte level is below normal, only distilled water can be added to them.

Precautionary measures

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

Important! If battery acid comes into contact with skin or clothing, wash the area with a solution of regular baking soda. In the absence of soda, simply rinse the places of acid contact with plenty of water.

If you have an alkaline battery, then if alkali gets on your clothes or skin, you will need to wash them with an acid solution. (Regular citric acid or a 10% vinegar solution will work for this.)

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

During battery operation, hydrogen is released from it through the ventilation holes. This gas is extremely explosive. Even a small spark from an accidental short circuit can, under certain conditions, lead to an explosion. Therefore, it is better 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 in the opposite direction: with the positive contact to the negative wire.

There will be no particular harm from this - the sizes of the positive and negative contacts are different and it will simply not work to put the negative terminal on the positive contact without using a hammer.

If you fully tighten the fixing nut on the positive terminal, and it still hangs loosely on the contact, check if you 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;
• carefully fix it with a regular mount;
• tightly put the positive terminal on the corresponding contact;
• tighten the fixing nut;
• then repeat the same with the negative battery terminal.

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

Attention! Do not use hard metal brushes to clean contacts or terminals! They leave deep scratches on the battery contacts and on the terminals, which leads to their heating during operation.

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

Easy Care

Every time you look under the hood, be sure 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 soda and hold for 15-20 minutes. Then wash off the resulting dirt with water.

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

Conclusion

Despite the simplicity of 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 is controlled by 5 on-board computers and another, sixth, which manages the work of the first five), it is better not to change the battery on your own at all, but to contact an official representative office or a service station.

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

Faced with a situation how to remove the battery recently. My wife and I returned from vacation, went to start the car, but the car wouldn’t start, didn’t react to anything at all. Immediately began to suspect that the battery sat down. The neighbor had a charger. I don’t even remember which terminal I took off 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 its place and started driving.

Volodya

Recently I was on a hunt, I forgot to turn off the headlights, they stood for only 20 minutes and the whole car would not start. A car passing by “lit a cigarette”, there were good wires, otherwise we would have to cuckoo in the forest. Came home fine. Everything was fine for a couple of days, then the 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 it starts without problems.

Paul

The battery turned 5 years old and then one frosty morning -20 autostart could not start the engine, even with the ignition key I could not breathe life into the car. And how it's not on time! In the evening I removed the battery (according to the instructions) and put it on charge for the night.

Igor Vasilievich

I think it’s not worth paying special attention to the spark that jumps on the terminal during removal. The memory in the watch, receiver, etc. puts 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 went to another city, leaving me our car. And on the street just crushed under -30. The car was on startup all night, and in the end Akum failed. I had to turn to a neighbor - a sincere uncle turned out to be))) Everything ended well, the neighbor charged at home and put it back!)

Lucy

My car was left to "spend the night" with the marker lights on. To go to work .. Well, my brother helped out, changed the battery. I didn't dare take it 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 you slightly increase the density of the battery electrolyte, then even in such frosts it is possible to start the car. And it turned out to be true! The car is hard to start, but I advise you to use this tip for operating batteries in cold weather)

Anton

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

Novel

I remember in my youth I did not attach importance to simple rules when removing a battery from a car. Therefore, its service life was reduced. AT modern cars designers have a battery (sometimes in the trunk, sometimes in the floor). I prepare the keys and look at the connectors and gradually release the terminals (I start with a negative 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 without haste. If the on-board computer in the car will need to be tested after its installation, the electronics and there may be problems with the alarm. Nowadays, it is not a problem to contact a car service in case of a failure.

Kirill

Most recently, they forgot to turn off the light in the car and left the city for a few days. Upon arrival, we were in for an unpleasant surprise - the battery was dead. 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 a cigarette for us, but it is worth remembering that you can’t light a cigarette if the electrolyte leaked out, the battery emits strong smell or warming up. 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 be in those situations anymore.
And I'd like to hear feedback on chargers ah, who uses what?

Nicholas

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 minus one is always removed first. Sometimes the terminal sticks, I use a solvent. I always remember that after removing the battery, the on-board computer can be weird, 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 at how an experienced driver does it once 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 modern models it can be hidden in the most unexpected place. Open the niche and use the wrenches 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, starting from the negative terminal.

Peter

The most basic and important thing when removing the battery is that the ignition key is in the driver's pocket, not in the ignition, not on the seat, not in the glove compartment, not on the panel. central locking can block all the doors and only a specialist with a crowbar can open them, or break the glass of the door. Such cases were, 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 the best option leave to charge in a closed garage at night!

Kolya R.

In my opinion, it doesn't matter which terminal to remove first! How many cars have been in twenty years, and these are pretty decent and fresh Land Rover, Passat SS and Honda CR-V, there was not a single problem. But with battery mounts, especially with those that are screwed onto threaded connections, sometimes troubles happened. Sometimes they rusted tightly, I had to use a rather rough metalwork tool, everything under the hood is shiny and 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 cans of the battery, when the electrolyte is actively boiling during a long recharge.

Sergey

If you leave the car for a long-term parking, then it is also advisable to remove the terminals, clean and seal them (wrap a plastic bag over an elastic band) until the next operation to preserve the battery charge. In winter, be sure to remove the battery in order to prevent freezing and complete failure of it. Before moving the device into a closed room, 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 operation, it is necessary to check with a multimeter, if necessary, carry out a complete preventive maintenance.

Tatiana

I only had to remove the battery twice. The infection is heavy - they ate it to the workbench in the garage (her husband had no time). I had to shoot after I forgot to close the driver's door and the car stood for a week in the garage. The battery is completely dead. So I had to buy a new one. The old one didn't hold a charge. When I put in a new one, I forgot the key with the key fob in the car, and when I began to connect the minus, the alarm went off. The doors were locked and there was nothing I could do. It's good that in the garage there was a box from under the signaling, and there was a small key in it. I removed the rubber plug on the signaling and turned it off with this key. And then home for the second key fob. Now I never leave the keys in the car and the second key fob in the garage.

Vladislav

I believe that it is necessary to remove the battery at least twice a year, especially if it is in 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 disconnection from the on-board network is clear - the first terminal is negative, then positive. If the nuts are very acidified, or even worse, dead rusted - in no case do not use brute force - roll up the lead terminal, go for a new battery. It is better to cut the nut with a grinder.

Lyokha

With the battery, as with any device that can shy current, you must handle it carefully and follow certain safety rules. If the vehicle is not expected to be driven 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 is a guarantee of the safety of the car from a short circuit. It is possible to break this rule if a mass switch is built into the car. 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 much effort to tighten the wire tips, as deformation will occur and subsequent similar procedures will not work. The wire ends will twist and have poor contact.

Laura

I try once again not to climb to the nodes of the car, but there are a few things that every driver (including women) must know and be able to do. Removing / installing the battery is just one of those. I had to shoot so far 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 a neighbor and carry out this operation under his control. I remembered that you need 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 your feet. Well, the neighbor said so. In general, I did well.

Ivanovich

Currently, modern drivers do not have the careful attitude to batteries, as before. 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. The work of removing and installing is really not difficult, on the one hand, and on the other hand, you need to know many features of this work. In my youth, when removing from careless shooting, I had to break the battery case, break the terminal on the battery, and if I had to remove and install it often, then break the wire of the negative terminal. The appearance of an injector and an alarm on cars also had to study the features of replacing the battery. Once, during a battery replacement, the alarm closed all the doors for me, along with the ignition key. It's good that this happened in the courtyard of his house, I used a duplicate. In general, this work should be carried out more carefully.

Oleg

Before removing the battery, you need to understand why? If the battery is out of order, then definitely remove it. Charge - you can not shoot. Required repair work, you need to de-energize, you also don’t need to remove it, just throw off the terminal. The battery closes access to other parts of the car, then you can’t do without removal. So we see that it is not always necessary to shoot. But if you really have to, then you need to remember that if you have a foreign car, where the electronics, secret police, on-board computer, removing the battery can be a problem. My neighbor in the garage changed the battery for a new one for AUDI 6, and so his brains flew off in the car and had to be dragged by a tow truck to a 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 the bar holding the battery with the keys, then carefully remove it and put it on a flat surface. By the way, the battery weighs from 18 kg, so be careful.

Max

Wires from time and flight from technical oils may lose their color, it is better to additionally mark them for polarity. At random, serious malfunctions can be made. And it is better to process the terminals with specials. spray before each removal and installation.

Alexei

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

Olga

I have an old 2108. So I have no problem removing the battery. But her husband has an Audi Q5 and he went on a business trip, and left the car in the garage with open doors and when he arrived he could not start it. Removed the battery and took it to charge. Then the car wouldn't start. The service said that the failure of the brain due to the disconnection of the battery. They said before you shoot, you need to connect another battery in parallel and only then disconnect the old one. And then I had to rewire my brain.

Elena

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

Kostya

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 problems, and if you have power windows, then do not forget to close the windows for a start, this is where all the preparations end.

I always remove the battery if 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 is guaranteed to start and you will go where you need to go. And without it, it's far from a fact. We have severe winters in the Urals.

Many motorists remove the battery from the car, taking it home at night. Do I need to remove the battery from the car in winter Or is it a relic of the past?

One thing is for sure - remove the battery from the car every day makes no sense. In winter, to extend the life of the battery, it is enough to remove it a couple of times a month and fully charge it.

Remove battery and it is usually necessary to carry it away to heat when the battery is already old. A serviceable and charged battery quite well tolerates spending the night on the street in both winter and summer.

If the battery cannot turn the crankshaft by morning, then taking it home every day is too troublesome. This is a clear signal that it's time to get a new battery.

When should the battery be removed from the car in winter?

There are situations when it is desirable to remove the battery, even if it is new and charged.

For example, if you do not use the car for a long time, then it makes sense to bring the battery home. For a couple of weeks of inactivity in the cold, even a new battery can sit down.

Also, the battery can be removed if you definitely need to go by car in the morning, and there are severe frosts on the street - minus 30-35 degrees. It is better not to take risks and bring the battery into heat, otherwise in the morning you may not start the car.

Many motorists in winter refuse 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 maintaining the battery in the winter, leaving it connected to the terminals in the usual mode for weeks or months. Such negligence can lead to a complete discharge of the battery or its failure due to the short circuit of one of the cans. 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?

In the conditions of a “warm winter” (when the air temperature in the place where the car is stored does not fall below -10 degrees), in order to maintain the maximum battery charge and not bother moving the battery, it is recommended to reset one of the terminals of the on-board network from the power source. We recommend removing the negative terminal in order to avoid the risk of the “plus” hitting the ground and short circuiting the on-board network. By removing one of the terminals from the car battery, it will be possible to greatly reduce the process of discharging 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 when the battery is completely disconnected from the vehicle's on-board network, the settings will be reset. electronic systems.

How to store the battery in winter?

The main thing to remember about the safety of the battery in the winter is its position in space. Never store the battery vertically or on its side. The power source, dry-charged or filled with electrolyte, must always stand horizontally.

To store the battery in winter, you need to 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 a pantry or on a balcony, it is better to give preference to a pantry or any other "dark" room where the sun's rays do not fall. The danger of sunlight hitting the battery during storage is that it can cause deformation of the case, and this will lead to malfunction of the power source after connecting to the car;
• The temperature in the place where the battery is stored must be above -5 degrees Celsius. You can leave the power source to winter in the cellar or basement, where the temperature, if it drops below zero, is not much;
• The room should be well ventilated and not have high humidity. This is due to the fact that during self-discharge, the battery releases 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 better preservation in winter - this is a lie. Moreover, before storage, 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: Only distilled water can be filled into the battery. Never top up with tap water or acid, as this may cause unwanted reactions that will destroy the power supply.

Long-term battery storage using boric acid without refueling

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

The battery is charged to the limit with the electrolyte that it contains;

Attention: Boric acid is susceptible to temperature changes, therefore it is necessary to store a battery filled with it in a relatively warm place at a temperature above 0 degrees Celsius. However, do not forget that the power supply housing should not be exposed to direct sunlight.

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 without checking at temperatures above 20 degrees Celsius for more than 9 months.

To restore the battery to a healthy state after storage using boric acid, follow the instructions below:

After renewing the electrolyte in the battery, you must 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 it will not be necessary to start the car with a dead battery.

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

There is a whole mass of chargers (memory). Among them there are both home-made devices and those bought in specialized stores. It must be remembered that the temperature of the electrolyte during charging increases, it begins to boil, toxic gases are released. Therefore, it is recommended not only to carefully ventilate the room, but also to unscrew the lids of the jars. 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 corresponds to 70 hours of operation.

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 pallet on which the battery is installed must be cleaned of oxide, it is often very dirty, so it can be brushed over metal and wiped with a clean rag. 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 seat under the battery has been corroded, as a result of which it is not reliable. In this case, a replacement is recommended. It is also desirable to pre-treat the battery, wipe it, wash it if possible, but you need to make sure that water does not get on the terminals and in the battery banks. It is advisable to rub the wires with sandpaper, as they oxidize at the points of contact, due to which the current permeability deteriorates. On this, all the preparatory work can be considered completed and proceed to the direct installation.

Learning how to properly install the battery

Lay 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 the mount may loosen on a large pit or bump, and the battery will be damaged on the impeller, but this only applies to cars of the VAZ family.

After we installed the battery in her starting position, fix the clamping bar. We have already said above that we have two poles on the batteries: plus and minus. You need to connect plus to plus, and minus, respectively, to minus. If you do not follow this simple rule, the device will quickly fail. In addition, a short circuit will occur, which can ruin almost the entire network, from the dimensions to the fuses responsible for the wipers, etc. The wires connected to the battery terminals should not be under tension, as they may break while driving , and that's no good.

What everyone should remember when working with batteries

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

• removal of the "minus";
• weakening of the "plus";
• removal of the clamping bar (battery mount);
• 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 back seat inside the car. In this case, the removal sequence is exactly the same and does not differ from the one described 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 the charge level as well as cleanliness are fundamental factors. Under no circumstances should you overcharge. As for removal and installation, after you have done this operation several times, you will not have a question: how to remove the battery from the machine, etc. The main thing is to follow the instructions, take precautions and do not work in a hurry.
