What terminal to remove from the battery. With a long parking lot, in order to avoid discharge. How to remove the battery from the machine how to properly disconnect the terminals of the battery

It so happened that the article about gathered enough comments and likes - both on the blog and on the Youtube channel. In it, I noticed that in order for the battery does not discharge, you need to "throw off" to the terminal, especially this is true if you leave a car for a long time - let's say for 2 to 3 months, or in general for the winter. Yes, and if you leave the car in the parking lot, say for a couple of weeks, it is better to remove it. However, my readers on the channel, a question arose - and what, you need to shoot a plus or minus? After all, they work in different ways! The question is fair and as I consider it very correct, so I decided to write this article and remove the video, I will decompose everything "on the shelves", as usual ...

Guys, what I want to notice - that you need to shoot the terminal and in the summer, if you do not plan to ride for a long time on your car, it will save your battery from the discharge. Indeed, in the on-board network there are currents of microchildren, which sooner or later will pull out the entire charge from the battery.

Why the battery is discharged with a long parking lot

Guys are easy, our battery is rigidly connected to a car network. Even when the ignition is turned off and pulling out the key from the castle, you do not cut off all consumers.

The point here is what, there are devices that "suck" energy even when the ignition is turned off. This can be attributed - alarm (there and beacons), a radio, on-board computer, etc. Of course, this is microcurrents for a couple - the top three days of downtime will not be able to discharge the battery, but in a month or two, the discharge can critically fall, say, to the same 12V, then the minimum is needed by recharging. Therefore, to avoid such leaks, you need to turn off the battery from the on-board network. It is done simply - remove the terminal.

Self-discharging currents

It is also worth noting - that the battery exists, the so-called self-discharge currents. Even if the terminal is thrown and the total chain is open, then the chemical processes inside smoothly discharge the battery. Already after 6 - 7 months, the category may be about 30% of the fully charged battery. The so-called "dirty top layer" can exacerbate the case, as a rule - the battery is on the street (under the hood), on its surface between the terminals, directly on the covers of cans, and various substances accumulate, it can be like - dirt, moisture, oil, residues Coolant - non-freezers, etc., they form a micropoline, which closes the electrodes, thereby increasing self-discharge currents. That is why it is so important to follow the cleanliness of the upper part.

If we talk about the positive and minus plates, which, then the minority has a big self-discharge. From time to time, they begin to dissolve in, highlighting hydrogen.

As I have already written from above, the discharge will not come instantly, but after 10 months the battery will lose half of its charge.

Why many do not throw off the terminal?

There are also several reasons and all of them ...

• Just can't , I do not know how, never discarded and do not know what it is (especially relevant from). Therefore, to begin with, read the article - how the battery works, then how to remove the terminal. Much clarify.
• central locking . The fact is that many cars have a central locking - that is, if you turn off the battery, you can close only one door with a driver's key, but the rest remain open.

There are two ways:

• We open the hood - then we close the door from the console - disconnect the terminal - close the hood. This is if you do not have latches from above the door, it also happens on expensive cars.
• If there are latches. We remove the Terminem - sit down in an outdoor car - handles omit all the "lamb" on the doors (passenger) - then lock the driver's door with the key.

The car is closed. Board If in Winter Street, lubricate the locking well with silicone for locks to. After all, there is a thaw and frost, water will fall, torture to warm up.

• Set up settings . Some drivers are experiencing that they will disappear, all the auto parameters will disappear. Guys are also bikes, all the data is firmly sewn into the ECU of your "iron horse", even if it justs without a battery for a long time, let's say half a year, they will not disappear! Maximum that can be lost, these are the settings of the radio and audio. But it is fixed in a couple of minutes.
• Be afraid of hijacking cars . Leave connected to work alarm and beacon (if any). But here I also want to object - if the parking lot is really serious, then your car is under serious observation (cameras, dogs, security, etc.). If this is a parking in the yard - I would be afraid to leave even 2 to 3 days on it. So if we leave for 2 to 3 months or simply do not use, choose the proven parking lot.
• Hope for the reliability of the battery. Many people write - and I "don't care", I did a serious company my battery, it will not discharge for a long time. There is a proportion of truth in it - there are more lead, the plate is stronger, but even they will not withstand 3 months of connection to the power system, without movement. There is an option to freeze your battery with a deep discharge. If you are not lucky, just throw your new, "twisted" battery.

In general, we definitely remove, you do not need to experience fate, it will simply be more correct. Well, now actually what you need to shoot.

What are you removing and why?

As you know, our battery has only two contacts, one plus, another minus. If this plus is suitable directly to the necessary consumers, such as - generator, starter, power supplies, ECU, etc. That minus terminal is "powered", which is said "for mass". What does it mean? Body car is a "metal" box that perfectly conducts electric current. So why pull the minus wires, if you can fasten the wire to the body from the minus of the battery, and then the necessary consumer from the body is powered by a minus. That is, the body is most and there is a minus of the car (more precisely, he goes through it). If you turn on the logic here and so everything is already clear.

Remember, always remove the minus battery terminal! It is done because, minus goes on the car body, and this is a very large inertial mass. Also, as I wrote from above, the minus plates dissolve in sulfuric acid themselves after a long downtime. Plus contact in this case is much in a more winning position, there is no such inertial load on it.

Of course, you can remove the "plus", it will also cut the machine's network! But this is not entirely correct, the mass of the body will adversely affect the minus terminal, it is self-discharge to accelerate.

Reliability and stability of operation modern cars Determined by many factors, among which and resource rechargeable battery. It can be sued unexpectedly and directly on the track, so the working state of the ACB should be supported by special devices. If the charge is minimal or the device needs to be repaired, then, as a rule, it is necessary to withdraw. It would seem that the task is elementary - several simple manipulations, and the battery is removed. In the case, inexperienced motorists face a lot of questions, the wrong solution of which entails the problem with new batteries. Others and at all doubt whether it is possible to remove the battery without the help of a specialist? The answer is simple - it is possible, but only with the knowledge of the subtleties of this delicate operation.

When do you remove the battery?

There are two main occasion for dismantling first when a block malfunction is obvious - it needs to be repaired or its final replacement is planned. Secondly, if heated, examination or conducting other operations that do not involve the replacement of the battery is planned. The fundamental differences in the approaches to the withdrawal regarding the mentioned reasons are not, but in the first case it is worth considering the contacts, the brand, parameters and features of the battery. Understanding how to remove the battery from the car is not enough if you need to install a new one in its place. In such cases, information about the old model will help with the acquisition of a replacement device.

In most cases, the battery is simply discharged, and to facilitate its charging, the motorist dismails the block. It is also worth considering that an externally unrestreprenerable ABB in fact may be serviceable. A critical sign, finding which, you can remove the battery for disposal, is the non-working recharging - in such situations there is a process of sulfate plates, stop or adjusting which no auto chemical age.

Preparation for battery seizure

The main thing is that it should be considered in this operation - this is the risk of depressurization of potent and even hazardous chemicals. Therefore, it is desirable to organize work outside the garage or other cramped room. In open locality, the process is performed freer and safer.

Knowing how to remove the battery from a car, reinforced with security measures, will save from unnecessary trouble. For example, to minimize the danger in the flow of electrolyte, it is necessary to provide appropriate substances and solutions. For example, soda alcohol or ammonia. If an alkaline battery is used, a weak acid solution will be required. These compositions will help on time to eliminate electrolyte traces both on the surface of the machine and on the skin, which, by the way, should also have individual protection.

Disconnecting terminals - with what start?

You can start when the ignition is disabled. Then turns off minus. This Accord terminal is associated with the structural elements of the machine, the engine and almost all metal items. It is important to take into account to understand how to properly remove the battery without the risk of random contact between the key, the terminal and metal of the body. This will lead to the appearance of sparks, which should be avoided. Conversely, when working with a minus, such situations are excluded by definition. When a negative contact is disconnected, you can safely begin to the second terminal.

Demonstration procedure AKB

The list of necessary tools is minimal: two keys are enough - by 10 and 13 mm. With the help of a suitable model, a nut is unscrewed by means of which the battery is secured. Then the locking bolts are then unscrewed, and from the front side it is necessary to remove the clamp. Now you can remove the battery, but so that the slopes and sharp manipulations are as short as possible. In addition, it is undesirable that the battery can come into contact with clothing and, even more skin.

When the battery is seized, it is recommended to perform a primary inspection and basic cleaning activities - this will be required for safety and no matter what is planned to be done with the battery in the future. First, it is necessary to estimate the state of the block relative to the tightness - cracks and traces of electrolyte leakage must be strictly fixed. By the way, the sequence of how to remove the battery makes it possible to detect possible body defects during dismantling.

The terminals, housing, clips, as well as other surfaces and elements are cleaned. If areas of corrosion from spilled electrolyte are found, it is necessary to use those most prepared solutions. In some cases, painting such zones is performed. To facilitate the described prophylactic measures, before removing the battery from the machine, it is worth providing a set chemicals, oils and napkins.

Accounting

In general, primary measures for servicing the battery seizite are marked. However, if its further use is planned, it may be necessary for serious care for the device. And yet before removing the battery, it is necessary to keep in mind the possibility of its further use.

Initially, the block should be rid of sodium carbonate. Also, the grooves of the acb in which the plugs are tightened. Ventilation holes are subjected to cleaning. The gas feed channels are integrated into the color plug complex, they should also be checked. Timely uncomplicated battery care measures will become a guarantee of good and long-term work by the car, and also minimize the need for regular removal and replacement of AKB.

How to install the battery?

Having understood how to remove the battery, you can go to the description of its installation. This procedure is extremely simple, but also implies knowledge of the nuances. In this case, the role of preparation is large, that is, in what state the battery is installed. Two indicators are important - the fullness of the unit by electrolyte and its density. The second can be checked only after 3 hours after filling. In case of insufficient density, recharging device is required.

Directly connecting the terminals is carried out in the opposite order relative to the dismantling procedure - you need to start with red. Next, the bolts and other clamps with fasteners are fixed. Having mastered the procedure, how to remove the battery, you can easily accomplish this part of the power source replacement event. In addition, if there is an opportunity, it will not be superfluous to use lithium lubrication, which will prevent oxidative processes in contacts.

Optimal location

If the battery is located near the exhaust manifold, then in the summer it is recommended to isolate the metal plate. In the winter, it is advisable to ensure the direction of radiator thermal energy to the battery, which will prolong the exploitation of the latter.

- This is a rather important element in the car. Its main purpose is to provide power to the nodes and to start the engine with them. At this moment happens the greatest flow The battery charge, which is fill in naturally during the normal operation of the car. But it happens that, or is subject to disconnection and even replacement. Few people know that after installing it back, the driver can expect minor troubles, to prevent which you need to perform some actions.

To begin with, let's consider the situations in which disable terminals. It is done during any work with wiring to avoid short circuit, as well as under repair fuel system. For example, controlling the state of the fuel pump, you can trigger the occurrence of the spark that will lead to ignition and very deposit. That is why manufacturers recommend disconnecting the battery for their own safety.

Turning off the battery It is performed as follows: First, the terminal is disconnected with the "-" sign, and then with the "+" sign. Connection is performed in reverse sequence. It is worth noting that when removing the terminals, the central locking will occur, and can also work alarm. This should be prepared: you should not leave the keys in the ignition lock, and the working anti-theft alarm must be disabled as soon as possible.

When the power is turned off, all information is automatically erased in the onboard computer of the car, assembled in all the time of operation. vehicle Since the last power outage. The regular radio tape recorder will stop working, to resuscitate which will have to enter a protective code that can be found from the documentation attached to the machine. In this case, the zeroing of "brains" will only benefit, because after that, all the errors have been removed from the memory, some of which could be listed there by chance.

After installing or reconnecting the old, you should start the engine and give it to work for some time on idling. After he reaches operating temperature, You can promote the motor up to 2500-3000 revolutions and let work in this mode for several minutes. All this time, the on-board computer will fix possible errors and record them in memory. This is necessary to restore the normal functionality of the system.

After the described procedure, the driver should take a test trip, the length of which will be at least ten kilometers. It should be controlled by the machine in different modes. Try sharply accelerate and also sharply reset the turnover if some errors will happen, they will immediately be fixed.

Do not try to avoid the execution of this without a binding procedure. After all, it can noticeably facilitate the further operation of the vehicle. In addition, its implementation is prescribed by automakers, pre-warning owners that in non-compliance with the requirements are possible incorrect operation of the vehicle, and any malfunction during its operation can lead to an accident.

The interaction of components in the car provides the driver and its passengers comfort and safety. But if anything fails, professional assistance is needed.

The battery in the car is of great importance, allowing the car to move on the road at night, lighting the road leaf in front. In addition to lighting and serving signals to other participants road The battery performs other functions - for example, starts the engine. Of course, such a demand for the electrician element in question leads to the need to replace the battery. And although to replace it is not necessary to go to the station maintenance, stick to a clear sequence of steps.

How to remove the battery?

Before disconnecting the battery, you will need to take precautions. It is worthwing to know that the battery in the car contains the amount of energy capable of mortal injury to a person! Moreover, inside the battery contains corrosion-active substances capable of producing flammable gas.

If you wish to understand the question, how to properly remove the battery from the car, prepare required tools and materials. For work, you will need: key extension, set of nozzles, protective glasses and gloves, old toothbrush, pallet, clamps, water and baking soda. Before you start, turn off the ignition, put on the protective glasses and gloves to protect your eyes and hands.

1. First, you will need to find a negative terminal on the battery, often allocated due to black coating. Often the negative terminal is indicated by the sign "-". Accordingly, the positive terminal is indicated by the "+" symbol.
2. Determine which nozzle you will need. The size matters if necessary, unscrew the nut with a negative terminal. First disconnects a minus terminal
3. Take the nozzle, substitute to the nut, located next to the negative terminal. Rate the size of the nozzle tolerance. The nozzle is on the key, for which the key extension may be required.
4. Turn the key against the movement of the clockwise. Disconnect the negative wire so that it does not touch the terminal
5. Similar actions are made with a nut on a positive terminal. Disconnecting the positive wire from the terminal, do not allow the contact of its bare end with the metal surfaces of the car
6. Disconnecting the battery, disconnect the mount, then lift the battery from the compartment. Pre-take care of third-party assistance, as Akb weighs up to 20 kilograms
7. Clean the compartment with a toothbrush and soda, and then give space to dry

After executing the above steps, you can start installing a new block and the subsequent connection of the AKB.

How to connect a new battery?

Now consider how to connect the battery in the car. Before the installation started proper training. From the corresponding connector, remove the pollution, dust and other trash, and then clean the inner plane of wire tips by means of fine-grained beams.

Before installing a new battery pack, you need to clean the terminals. The sequence of the installation of a new battery does not differ from the installation of the old block. Take the clamping plate, and then tighten the clamping bolts. Perform work carefully to not harm the integrity of the product. To connect the battery, use the following algorithm:

1. Observe the reverse sequence of actions when installing the battery. Connect the "+" wire to the corresponding terminal first, and then connect the wire "-" with a negative terminal.
2. Some manufacturers for security reasons make conclusions of different diameters, due to which random confusion is prevented when the wires are connected to the terminals.
3. Tighten the fastening nuts tight using the key.

Installing a new battery pack Most often due to the exhausted resource of the old one. If you are not sure own power and tool skills, take advantage of the support of the technical center personnel.

Perform work in open space, because the street gases do not accumulate. It is advisable to remove jewelry, including rings and bracelets for hands. Use individual means of protection - Dielectric and safety glasses gloves. Wires should be placed as far as possible from the battery. This is necessary in order to prevent the wires from entering the terminals and metal parts of the car.

Note that after disconnecting the wire with a positive terminal, the residual current can harm the operation of the car electricians if the wire is touched with the metal surface of the body. It can also serve as a short circuit.

Remember that standard batteries for cars are able to generate a current by force to hundreds of amps, which is equivalent to the charging of the welding machine.

Batteries B. hybrid cars Can produce 300 volts of energy, and this indicates a human strength life and human health. Wiring is often differentiated in color. You will be able to reduce the likelihood of shock, if you use gloves, as well as an insulation tool.

What to do is extremely undesirable?

Stick up certain security measures to protect themselves from possible troubles, financial waste. Do not commit actions that could lead to damage to the battery case. Do not tilt or turn the battery. Also do not damage the plugs of the casting holes, the neck.

Do not tighten the acid and do not save the discharged battery, especially at a minus temperature. Having damaged contacts, you risk gaining additional costs, disseminating equipment. Be careful while reading and connecting the battery in the car.

Many laugh when they hear the question of how to remove the battery from the car. But, even in this, simple at first glance, there are some moments, then you can remove correctly, you can remove as it fell.

If it is wrong to remove the battery from the machine

When disabling and dismantling automotive AKB As it fell, problems may occur in the operation of the electronics system and the closure of the battery itself. If the battery is damaged in this case, then best optionbecause if there is a short circuit (KZ) of the on-board computer, then it will be repaired much more expensive.

Correct battery with car

First of all, you need to see which keys will be needed to remove the mount. Usually the fastening system is tightened with a turnkey nut at 13 or 10 mm.

Disconnection order:

1. Turn off the ignition, pull out the key and put in your pocket, because some cars block doors if you turn off the power.
2. Turn off all electrical appliances: magnetol, headlights, air conditioning, etc.
3. If the machine is installed in the machine, then after turning off the ignition lock key, turn off the mass.

Relief terminals

It is very important to know! The first terminal (-) mass is removed.

This rule concerns all cars: injector, carburetor, diesel, with immobilizer (immo), with alarm, etc.

The minus voltage of the battery is connected to the car body. If you disconnect the terminal (minus), then the car body is turned off. This is important when when removing the terminal (plus), the metal object is accidentally touched by the body. When the mass is turned off, the closure will not happen.

If the terminal for the mass is not removed and accidentally closer to the plus contact to any metal site of the body, then a short circuit will occur, as a result of which it can be burned down, and can also electrical appliances. IN modern machines there is electronic blockswhich are not disconnected and remain under voltage.

If in a closed position, the battery will be some time, it can light up or melt.

1. Remove the terminal (-) and remove the wire away. The wire has an elastic deformation
2. Remove terminal (+).
3. Remove the mount and pull the battery.

It happens that the terminals are bought, you can slightly knock on them to move away. The oxidized raids must be cleaned with a brush and, for example, VD-40.

How to remove the battery, if there is a on-board computer in the car

After removing and installing the battery, the saved onboard computer stored. Therefore, it's just not to remove once again the battery is not recommended.

Possible problems with alarm

Usually, the removal of the battery does not harm the protection system, but rarely the following problems may rarely occur after the power is disconnected:

• loss of keys and remote controls;
• failure of additional signaling functions.

Possible problems with the magnetic

Before removing the battery with a car, you need to see if a protective pin-code is on the radio. If there is a PIN code, then make sure that it is. Or disable the request of the IDU code. As for the radio, the frequency of the receiver will need to be configured again.

What you can not do with the battery:

• disturb tightness;
• do not lay on side;
• toss
• closer, for example, to find out what will happen if you close;
• store in a strong frost.

Safety technique

The weight of the batteries for cars is large, so if the handle is weak, hold for the bottom so as not to drop.

If rechargeable acid, got on the skin, then not a hollow with clean water, preferably a solution of food soda.

Do with the battery, charge, check the density of the area, to top up distilled water, etc. In a well-ventilated room. The working battery highlights hydrogen gas through a special small hole in the battery case.

How to connect battery correctly

When installing, the main thing is not to confuse plus and minus. The terminals after the tightening should be tightly sitting, if the terminal can still be turned to the fingers, then it is impossible to replace the terminal.

Installation procedure:

1. Put the battery in place.
2. Tighten the mount.
3. Throw the plus (+) terminal and tighten.
4. Throw minus (-) terminal and tighten.
5. It is advisable to lubricate the compounds with a special lubricant, or a lithol.

Care

There are also rules for care of the battery. If during the inspection there is an oxidation fall, then you can remove them and put into the solution (water + soda) and hold 20 minutes there, then clean it, install and lubricate.

In traffic jams there are special ventilation holes, they should be cleaned if they are clogged.

Output

There are cars that are stuck with electronics to a maximum, for example, Volkswagen Faeton (Volkswagen Faeton), in the design of which there are 6 on-board computers, five of them has its own sites and nodes, at one - control the work of these five computers. Therefore, it may be more expedient to replace the battery in a hundred.
