Why the battery in the car runs out in the summer and how to prevent it

Summer is in full swing, and it seems that the owners of foreign cars and domestic cars said goodbye to car problems until the next frost. But for many drivers, the headache during the operation of vehicles can only get worse with the arrival of a hot summer, and most often, in addition to the engine, oddly enough, batteries suffer, experiencing increased wear due to high temperatures.

Why car battery runs out in summer and how to prevent it

The main reasons why a battery can run out in the summer heat

For many, this may be a revelation, but it is in summer that car batteries experience a shock dose of overload, which, if not, will kill The battery at all, will contribute to its speedy failure with the arrival of autumn frosts.

It's all about the physical and chemical processes that take place inside the battery, invisible to the human eye, which in the hot season can cause increased wear on the device, for example:

1. Operation at elevated temperatures causes active oxidation of the battery terminals, which in turn leads not only to faster battery discharge, but also to a decrease in the service life of the device itself.

2. Battery boiling is a common thing in a car left unattended by the owner for a whole day under the scorching sun. The result of such a long stay may be exposed zinc plates and the appearance of a natural salt deposit on them after the evaporation of the electrolyte.

Each time after such a temperature shock, the battery will work less and less efficiently, and by the middle of summer it may completely fail. building.

3. Another no less dangerous phenomenon occurring in the battery under the influence of high temperatures can be called self-discharge processes. At low temperatures, self-discharge values ​​are minimal, but as soon as the battery is heated to critically high temperatures, a dangerous electrical factor will rapidly drain the battery until it is completely discharged, which, after several cycles, threatens to completely replace the device.

4. Sometimes elevated temperatures can cause the failure of a completely different device – a generator. Long-term operation in hot conditions leads to burnout of the winding, short circuit and even mechanical destruction of the device. Naturally, after the generator fails in the summer, the battery will naturally discharge.

5. Another cause of premature car battery drain is too many consumers when the car is stuck in traffic and moves like a turtle, raising the engine speed for only a few seconds. At the same time, the battery does not even need sultry heat to stop receiving the right amount of electricity and soon be completely discharged.

In some modern cars, automation maintains an ideal balance of charging and discharging the battery, not allowing the last indicator to be exceeded, which contributes to the constant maintenance of the battery in working condition. But there are relatively few such cars, and the vast majority of them, having high mileage, sooner or later still begin to experience problems with battery discharge.

How to prevent battery discharge in summer< /p>

It is much easier to discharge the battery in a car than to charge it – any car owner knows this, who at least once left the headlights or radio turned on at night. In this regard, it is recommended to fulfill a number of simple requirements that will keep an important part of the vehicle in working condition for as long as possible.

To begin with, make it a rule to park in the shade, especially if you plan to park for a long time, and the sultry rays of the sun “beat” right on the hood. Even in forty-degree heat, the saving shade will be able to protect the devices of the engine compartment from overheating, and there will be almost no chance of getting a battery replacement with the advent of winter.

In order for the battery to receive maximum electricity from the generator, it must be ready to do this itself without any obstacles.

To do this, with the onset of summer, you should check the density of the electrolyte, top up with distilled water if necessary, and also lubricate the battery terminals with grease. The conductive properties of the battery will increase at least one and a half times, but the self-discharge of the battery, on the contrary, will decrease.

A dirty battery heats up much more intensely, damaging its internal parts up to their complete failure. A simple wet cleaning of the battery at the same frequency with which you check the oil level in the engine will allow you to remove a decent share of the critical overload in extreme heat and save the battery from discharging.

Let it sound trite, but try to change the battery in time battery to a new one – do not wait until it responds with the lifeless rumbling of the starter relay. The same applies to the timely maintenance and replacement of the generator, if its operational wear has approached critical.

A working generator will regularly supply all the electronic systems of the car with electricity, provided that the battery is working properly, the wiring of the car’s on-board network is working and correct alternator belt tension, which should be checked from time to time.
