The problem of car battery freezing becomes relevant every season with the advent of severe frosts. As practice shows, it is easier to insure against such problems than to get out of the situation every morning in a hurry to work or on other matters. But it is impossible to foresee everything, and heating systems can fail at the most crucial moment. In this regard, the question arises: "How to revive the battery of a car?" There are several approaches to resolving the situation, and in each case one or another option will be the most effective.

Using a different battery

It is not always at hand to have a free working battery that will give a “light” and thereby restore the main unit to working capacity, but in fact this is the easiest and fastest way to solve the problem. For example, you can turn to a neighbor for such help or ask nearby car owners - it depends on the possibilities and specific circumstances. Now the main question: "How to revive the car battery by "lighting up"?" To do this, you should have ready a connection diagram for a specific block by terminals. However, experienced motoristsknow the nuances of handling battery wiring by heart. The procedure usually consists of four steps. First of all, the “lighting” wire is put on + of the working unit. Further, the other end of the same cable is put on the + of the problem battery. Two “minus” connections are made in the same way, but you only need to start with a non-working battery.

Awakening the main electronics in the car

It is possible that for one reason or another, restoring the block with another battery will not be successful. In such a situation, it makes sense to immediately start all the heating systems available for activation. In a modern car, they should be enough to indirectly warm up the electrolyte. For example, you can start heating seats, steering wheels, windows, stoves, etc. At the same time, the question of how to revive a car battery without a charger can also be solved by turning on optical devices. Headlights, fog lights, parking lights - these and other devices themselves emit thermal radiation, not to mention the communications to which they are connected.

Using the launcher

A rather progressive and relatively convenient way to defrost the battery is a quite typical heater, which is located in the cooling system. However, it is not so important which heating system will provide activationfeeding element. More important is how it will work. For this, starting devices are provided that operate either on a remote basis directly on commands from the user, or according to an embedded program. That is, the question of how to revive the car battery, in this case, is shifted to electronics. It is a common thing when the driver sets the heater with the starting device to the heating mode at certain intervals in the evening, after which he calmly goes home. But it is important to take into account the disadvantages of such schemes. Firstly, one way or another, the heater will work from the same battery, that is, in the morning you can get a battery with a serious percentage of consumption. Secondly, the optimal mode of such heating will not be constant, but periodic, for example, 15 minutes. of 60. Such frequent warm-ups can adversely affect the electrochemical qualities of the unit.

Direct launch attempts

One cannot exclude the possibility of a completely typical start of the machine without third-party methods. However, here, in order to increase the chances of success of the event, certain rules should still be followed. For example, even before starting, you need to turn off all energy-consuming electronics and equipment in the car. Next, the clutch is squeezed out, and you can start trying the factory. In the case of injection engines, it is better not to touch the gas pedal. You should be prepared that the first attempts will not live up to expectations, but it will be wrong to refuse further actions, since the second and third series of launchesmost often occurs in more favorable conditions. In the question of how to revive a car battery through serial engine starts, it is important to consider one nuance. In principle, the probability of a successful launch will be determined by the operation of the starter. If it starts spinning longer as you make attempts, then it makes sense to continue the procedure, and if it retains its behavior after 7-8 attempts, then it is probably better to stop.

What can not be done to revive the battery in the cold?

In general, it is advisable not to perform any actions with the battery pack in the cold. Although many car enthusiasts share their successful charging experience at temperatures of the order of -30 ° C, manufacturers strongly recommend taking the battery to a warm place already at -20-25 ° C. True, and here it all depends on the specific model. If, nevertheless, there is a hopeless question of how to revive a car battery in a frost away from the city, then it is best to seek help from specialists. The fact is that even attempts to "light up" in such conditions can provoke an explosion of the block.

If it's not cold

Any attempts to start a he althy battery process can lead to nothing if the electrolyte filling is in an unusable state. That is, even a low temperature is not the reason for the failure of the power supply to work, it just lost its electrochemical properties. How to revive an old car battery in such a case? First of all, it is necessarywarm up the battery. To do this, you can either activate the heating system in the car, or take the device to the house. Next, the battery is checked on voltage measuring devices, and then you can attempt to charge. The result of such a check will be either a conclusion about the complete unsuitability of the device for work, or the need for repair.

How can I prevent my battery from freezing?

The most common and recommended way to prevent a battery from freezing is to bring it indoors overnight. And here there are two important nuances. First, you should carefully implement the procedure for removing and installing the unit, since the liquid electrolyte may spill if the case is disturbed. Secondly, the question of how to revive a car battery at home at room temperature is also important. Actually, you can not worry about the efficiency of heating and do not use special tools. In this part, the main thing is to isolate the block itself from the place where people are.

Should I use additives?

Today, any problem with the technical basis of the motor group can be corrected to some extent by modifiers. An example of this is gear and engine oils. There are also special compositions that improve certain properties of the electrolyte. Most of them act to prevent the sulfation process, but there are also frost-resistant mixtures. Question about how to revive a maintenance-free batteryvehicle using additives is ambiguous. First of all, it must be said that they are not suitable for a block that is already in a frozen state. Their task is to prevent negative factors of interaction between the battery and low temperature. But before using such tools, you need to familiarize yourself with the recommendations of the manufacturer of a particular model in terms of the use of modifying mixtures.

Conclusion

Many of the problems associated with the operation of the battery can be avoided even at the stage of its purchase. In the question of how to revive a dead car battery in conditions of remoteness from civilization, a lot will depend on the characteristics of the unit itself. Today, manufacturers produce special models that are initially equipped with enhanced protection against external influences. The most successful developments show an example of frost resistance of the active substance itself. At the same time, unlike an electrolyte improved with additives, such an electrochemical filling fully retains its working qualities, giving off a sufficient charge in accordance with the standards.
