Fast battery discharge: the main reasons

An in-car battery is essentially an advanced battery that stores charge from the generator and, if necessary, supplies voltage when the engine is started. In the process of using the car, the battery may be discharged, requiring timely recharging from the car owner. Let’s talk in more detail about the main reasons for the rapid discharge of the battery and how much for scrap car.

Generator breakdown
One of the reasons for the rapid discharge of the battery is the breakdown of the generator, which cannot supply the required amount of electric current to the on-board network, respectively, the charge from the battery is used to operate the engine and various electrical consumers, which leads to a rapid discharge of the battery. That is why, if you notice that the battery on your car is quickly discharging, the first step is to check the condition of the generator.

Poor wire contact
Often the reason for the rapid discharge of the battery is poor contact of the wires, which oxidize over time, which quickly destroys the battery. Small short circuits may also occur, especially when non-standard electrical appliances are installed in the car. From time to time it is necessary to check the terminals and electrodes of the battery, which should be free of rust, dirt and traces of oxidation.

Worn out battery
As the car is used, the battery begins to wear out, the lead plates in it crumble or become covered with deposits, which significantly reduces the capacity of the batteries. As a result, such a battery, which according to the documents has a capacity of 60 ampere-hours, hardly gains only 15-20 amperes, which is clearly not enough for the battery to work properly.

Low air temperatures
In winter, the battery has an increased load, it is more difficult for the starter to crank the engine in order to start it, therefore more voltage is required, and this significantly reduces the battery life. Such problems can be solved by proper storage of the car, which is left overnight in an insulated garage or in a warm parking lot. As a preventive measure, it is recommended to recharge the battery before the onset of cold weather, which allows you to easily and fully meet the cold winter.

Small runs
The principle of operation of a car battery is extremely simple, to start the engine from the battery, electric current is taken, and while the car is moving, the generator generates electric current, which is accumulated in the battery. If the car is used for the minimum duration of trips, then the generator simply does not have time to charge the battery, which ultimately discharges to zero, being unable to start the car’s engine.

Let’s sum up
There can be several reasons for the rapid discharge of the battery, first of all, it is a breakdown of the generator or an aging battery that has lost its capacity. Oxidation and poor wire contact or low air temperatures are also possible. Regardless of the reasons for such problems with the batteries, if you notice that the battery holds a charge worse, you need to diagnose it or restore the battery.
