"Hot" start: 4 reasons for an unexpected breakdown of a car battery in the heat

It seems very strange to pay attention to the appearance of the car and the cleanliness of its interior, and remember about its technical part only when it's too late. For example, many motorists, whose cars look perfect on the outside, do not even know what condition the battery is in, at least. And in vain ...

It happens that the engine does not start at the most crucial moment, and this happens not only in frost, but also in the summer heat. The AvtoVzglyad portal found out why the battery loses starting power, and what to do to extend the battery life.

The battery does not like extreme temperature changes. And many motorists have experienced battery weather whims when freezing weather sets in in the region. However, the car may not start even in extreme heat. After all, if it is +35 outside, then under the hood the temperature can reach all +60, or even higher. And this is a very difficult test for the battery. However, this is not all the reasons.

To reduce the effect of heat on the battery, it is necessary to follow a number of recommendations that will help maintain its health. Bosch experts, for example, recommend adhering to a whole bunch of rules. Do not leave your car in open parking lots under the sun. It is necessary to check the state of charge of the battery more often, and if it requires it, then recharge the battery - in an open circuit there should be at least 12,5 V, and it is better if this figure is 12,7 V.

The condition of the terminals must also be perfect. They should not be oxides, smudges and pollution. It is necessary to monitor the correct operation of the generator. And in the event of a battery recharge, for example, when traveling long distances, let it “let off steam” - turn on lights and other devices that consume a lot of energy. Remember, overcharging is also bad.

If the battery is old and the need to replace it has been diagnosed, then you should not delay with this, but immediately install a new battery and continue to follow the above recommendations.

Extremely negative effect on the battery and irregular use of the car, and short trips. The thing is that even in the parking lot, the battery works, energizing the alarm, locks, keyless entry sensors and much more. If the car has been parked for a long time, after which the bulk of its trips are short distances, the battery will not recharge properly. And it also accelerates its aging.

Therefore, after a long period of inactivity, it is better to recharge the battery. After that, you need to make it a rule to let the car run for at least 40 minutes at least once a week. And this will avoid problems with the launch.

If you have not changed the battery since the day you bought the car, because there were no complaints about its operation, this does not mean that it is in good condition. The power of the battery is somehow reduced, and the reason for this is corrosion and sulfation, which do not allow the battery to charge properly. To make sure there are no problems with the battery, it, like the whole car, needs to be occasionally shown to specialists, and even, if necessary, to carry out maintenance.
