Do I need to remove the battery from the car in winter. Storage of different types of batteries in the winter. What not to do with the battery

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.

Despite its relatively simple device, car battery still remains one of the most complex and incomprehensible parts of a car. Traditional questions related to proper operation motorists have quite a lot, and one of them is the question of whether it needs to be charged, how often to do it, and whether it always needs to be removed for this. Any battery needs periodic charging and, basically, for this you need to remove it - for example, with a mandatory Maintenance.

Charging will also be required if it just sat down, and is not able to provide adequate starting current. This often happens when an electrical appliance is running in a car all night - a radio tape recorder, headlights or dimensions, interior lighting. In other cases, the battery does not need to be charged. Subject to regular monitoring of the battery voltage, which recommended 4-5 times a year. To do this, it is enough to use an ordinary ammeter. In cold weather, the frequency of control can be increased.

Charging the battery - to remove from the car or not

In general, it is much more convenient to charge the battery that is removed from the car. So it can be carefully inspected for damage to the body, cleaned, check the electrolyte level and its density - and all in a comfortable environment. But car owners with a huge amount of complex electronics try not to do this, motivating possible problems with electronics arising after the charged battery returns to its place. In fairness, it should be noted that such fears are well founded.

The fact is that most complex on-board electronics are extremely sensitive to power outages. There are many cases when a newly supplied battery disabled sensors, controllers or on-board computer. The owners of such cars by hook or by crook try to charge the battery without removing it from the car. Or they go to the other extreme - they do not charge the installed battery at all, hoping that the on-board charging system will do this.

This is far from true. The fact is that while the engine is running, the battery is recharged by the alternator. But at the same time, it is necessary to ensure maximum safety of the process. In order for the gas emission process to remain under control and not exceed normal values, a special regulator is located near the generator, which is responsible for ensuring that the charging current does not exceed 14 V, while 14.5 V is required to fully charge the battery. In this way The car battery is never 100% charged.

Proper battery charging without removal

So, the answer to the question of whether it is possible to charge the battery without removing the terminals is yes. Therefore, you need to understand how to do it correctly, quickly and safely. To begin with, it is worth bearing in mind the fact that even the ignition key removed from the lock does not block the power supply to some devices. Fine, the supply voltage of all auto electronics does not exceed 12 V, while the charging current for the battery is 1.5-16 V. Therefore, if there is no certainty that all electronics are de-energized, it makes sense to remove the negative terminal from the battery - this will save the devices.

When charging the battery without removing it from the vehicle, proceed as follows:

• release the battery from the protective cover, remove the metal bolts, clean the upper surface, including the terminals;
• check the electrolyte level, if it is lacking, be sure to make up for the lack of distilled water - otherwise there will be no 100% charge;
• prepare a charger - it must be disconnected from the network, when connected, strictly follow the polarity;
• plug the charger into the network.

Attention! With this method of charging the battery, it is unacceptable to use home-made or outdated models of chargers, since it is extremely important to provide “high-quality” current and accurately maintain the desired voltage. This is the only way to charge the battery without removing it from the car.

How long does it take to charge well?

If you can charge the battery without removing the terminals, it is definitely possible, but with the time it takes to fully charge, everything is not so simple. The time it takes to charge each battery is different. So, especially powerful batteries charge much longer than low-capacity batteries. The time of full charge is also affected by the degree of its discharge - in the absence of energy in the battery, it will take quite a lot of time to charge it. Of course, the strength of the charging current, and the ambient temperature, and the charger itself also matter. Look at practical process charge and its time can be on the video:

The purpose of the charge also matters. For example, if you urgently need to charge the battery without removing it from the car, then in order to start the engine, you can do the following:

• disconnect the wires from it;
• connect the charger, then turn it on;
• set the current value to the limit;
• wait 15 minutes;
• turn off the "charger", connect the wires and start the car.

Such a measure is forced, and you should not resort to it too often. For a better and full charge, it is better to remove the battery. After completing all the necessary preliminary steps (cleaning, checking and correcting the electrolyte), leave it connected to the charger for the whole night. Just don't forget to leave the plugs unscrewed. The end of a charge cycle is best judged not by time, but by the charger.

Important! The arrow of its indicator should be located on the left side, either at 0 or below.

New battery - should it be charged

A newly purchased battery can also be charged without removing the terminals, but many motorists are concerned about the question - is it necessary to do this. It is worth starting with the fact that it will be new only for the buyer. Until the moment of purchase, it could “collect dust” in the store for many months, and if after purchase it is immediately installed in a car, its power may not be enough to start the engine very soon, especially in winter. So it would be more correct to charge it first, and only then begin operation.

Regardless of which battery is being charged and how - removing it from the car or not, all precautions must be observed, since improper charging can end very badly. The first thing to pay close attention to is good ventilation. In the process of "feeding" the battery releases into the surrounding air a huge amount of chemical compounds that are extremely aggressive for humans. These include sulfur dioxide, arsenic hydrogen and many others, and in addition, a huge amount of hydrogen, when combined with oxygen, forming an explosive mixture.

In addition, it is necessary to work with the battery only with gloves, since sulfuric acid can cause deep chemical burns of the skin. Naturally, if you start the charging process with the lids of the cans closed, the battery is very likely to explode. In the event that the charge is homemade devices, you must also remember the approximate time for the end of the charge, since overcharging is also harmful to the battery, like a complete discharge.

Removing the battery from the car is a task that every car owner faces. This may be required to replace the battery itself, service it or temporarily store it, for example, in winter period 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 a niche in the trunk floor, under back 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).

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

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 outage to 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 the battery is removed or disconnected, the on-board computer loses all stored data received from sensors in various vehicle operating modes.

Accordingly, after installing a new battery, you will need to test the car for different modes to have the computer record and store the required settings in memory again. 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 normal 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. (For this, the usual lemon acid or 10% vinegar solution).

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 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 special tool for cleaning 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 fixing nuts, you can lubricate the terminals 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

Think, special attention it is not worth giving a spark that jumps on the terminal when removed. 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 is always a couple 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. Fill the engine for the winter winter oil it will be much easier for him. 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. V 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’s worth remembering that you can’t light a cigarette if the electrolyte has leaked out, the battery emits a strong smell or heats 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 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. 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 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, it is not the best option to leave it to charge in a closed garage overnight!

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 those that are screwed on threaded connections sometimes there were freezes. 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.

Sergei

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.

Tatyana

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, they are 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 ends, 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

At present, at modern drivers there is no respect for 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's 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.

The battery is needed to start the vehicle's engine. His goodness makes stable job mechanism. Vehicle downtime, which often occurs in the winter, does not have the best effect on the condition of the battery. Storage rules in the cold season will help maintain its performance.

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

A maintenance-free battery does not allow you to check the electrolyte level, but requires periodic charging

A dry-charged battery requires periodic checking of the electrolyte level and the addition of distilled water.

Is winter storage required?

Some motorists 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 - it makes no sense to perform such a procedure every day. In winter, if the frost does not drop to 30 degrees, and the car is used regularly, it is enough to remove the battery twice a month to charge it.

It is also possible that the battery is already old, so it does not withstand spending the night outside in the winter. In this case, you also need to take care to bring it into heat. Although in such a situation it is better to purchase new battery, since it is troublesome to constantly remove it and bring it home.

Owners who rarely use the car in winter should take care of keeping the battery warm. Even if it is fully operational, it will sit down in idle mode in just two weeks. Bring the battery into heat at night if severe frosts are expected. In this case, you should not take risks and leave the device in the car, otherwise in the morning it may simply not start. If the car is not used at all in winter, the battery is removed and stored separately from it throughout the cold season.

Preparatory work

To prevent the battery from being discharged during downtime, it is necessary to disconnect one terminal from it. In this case, the loss of charge will be, but insignificant. but the best option the battery will be stored in a warm room in the winter. When the battery is removed, the car will painlessly perceive the absence of voltage. You could even say that it will benefit him.

Dry battery

Preparation of a dry battery is carried out in the following way:

1. The corks of the jars are unscrewed, and the electrolyte level is measured through the holes using a glass tube. Its quantity can also be estimated from the marks that are present inside each can. If the battery is transparent, the electrolyte level is visible from outside. In this case, marks are usually applied to the battery case. The electrolyte level must be within 12 mm. If the value obtained is less, it is required to add 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 greater, distilled water is added, with a lower value, battery acid is poured.
3. The surface of the battery is washed with a solution of baking soda to neutralize the acid, and the terminals are treated with conductive grease.
4. The body surface is checked for damage.
5. The battery is charged, wrapped in plastic wrap or a rag to avoid possible external influences, and placed in the designated storage area.

If it is not possible to charge a serviced battery, fill it with a solution of boric acid (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 degree of charge of the device is estimated - 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 of traces of contamination.
4. The battery is wrapped in a rag or plastic wrap and sent for storage.

Gel

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

1. Recharge 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 a place to store the battery and place it in any position.

The gel battery is able to work even with a damaged case, but it still doesn’t hurt to check it.

for motorcycle

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

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

Home storage rules

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

Batteries should not be placed near hygroscopic materials, as acid fumes can damage them.

The storage area should be dark, dry and well ventilated. The optimum temperature is 0˚С. During storage, the battery should 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 degree of its charge every month in order to increase it if necessary.

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

Unattended

The storage requirements for a flooded battery are practically the same as for dry-charged batteries. True, you don’t have to check how tight the plugs are. The instrument 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 adversely affect battery performance in the future. If the battery has been used for less than a year, it does not always require additional charging. In other cases, 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 next time. Therefore, a fully charged battery must be delivered to the storage room. If it is serviceable, most likely, you will not have to carry out any manipulations with it. Although, periodic checks do not hurt. Gel batteries withstand temperatures from -35˚C to +60˚C and can be installed in any position. The room does not require additional ventilation.

Motorcycle

If the motorcycle is in a dry garage that is heated and its temperature is at least 15 ° C, the battery can not be removed. It is enough to restrict ourselves 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 is worth noting that this must be done slowly, at the same pace at which it was filled. In time, draining the acid takes about 20 minutes. Then the device is washed several times from the inside with distilled water. It is advisable that she stand in the battery banks 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 adjust this indicator, focusing on the marks.

After performing these steps, the device is completely ready for operation, it can be installed in vehicle. The terminals are connected in reverse order when compared to the process of removing the battery.

If stick established rules If you store the battery and use it correctly, it will last for a very long time.
