Reasons for discharging a battery

The battery of our car is an element that we must change periodically. Over time, it wears off and there comes a time when we can't start the car. This can be more noticeable in the coldest times of the year, for example, in the winter that we are now. In the event of a dead battery, an emergency remedy may be use tweezers.

Thanks to the battery, the car receives the electrical energy needed to power our car. That's not all, since with the battery we can roll up the windows, turn on the lights and also listen to the radio when the engine is off and also when the alternator is failing.

To find out the reasons for discharging a battery, first we must know what a battery really is And what components does it have? We must know the nominal voltage of a standard battery, or what has been the same, the difference in voltage between the positive and negative terminals.

A battery is made up of six elements. If we remember, years ago maintenance batteries had six vessels that could be open for maintenance. Each of these glasses corresponds to an element, whose voltage is 2,1 volts.

Taking this into account, we have as a result that a battery of six vessels and 2,1 volts each, has a total voltage about 12,6 volts approx.

The battery performs hundreds of loading and unloading processes that, with the passage of time, are damaging it. The battery is discharged when supplying electrical energy to the motor and the rest of the electrical elements of the car. To charge the battery, the vehicle has an alternator to charge itself.

A battery can wear out more easily when the alternator of our car is in poor conditionoo does not send a constant voltage to the battery. The battery can also deteriorate due to the evaporation of the distilled water that is in contact with the electrolyte.

Also when the environmental temperature is excessively low, it causes greatly decrease battery performance, getting to deteriorate.
