Thanks to the operation of the battery and the engine is started. The battery smoothes the voltage jumps, feeds the electrical appliances in those periods when the generator does not work. The problem with which many car enthusiasts face are fast battery discharge. It happens that the charge of the battery is enough for just a few days. There are several factors affecting the charge level of the battery.
1
The simplest reason for the discharge of the battery is not turned off the overall lights. During the next trip, the battery charge will be recovered.
2
Contacts should always be well twisted, and the terminals are protected. Terminals can be easily cleaned with fine-grained skins. To do this, you must first disable contacts from the battery. Disconnect first minus, then plus. Contacts are joined in reverse order.
3
The permanently turned on the trunk light can cause the battery discharge. To check it, you need, without opening the trunk, look into it from the salon. If the light burns, then the problem is in the sensor.

Old battery is another of the reasons for its quick discharge. To check the battery performance, there is a special device "Load plug", with which the auto electrician can analyze the battery power level. If the battery has developed its resource, the electrical system in the car does not require diagnostics. About 90% of batteries are non-servant, and their validity period is about 3 years. In other cases, the battery operation can be restored. To do this, rinse the battery, replace the electrolyte and charge the battery.
5
Car alarm, mostly satellite, can quickly discharge the battery. If the car with satellite signaling was not used for two weeks, the battery during subsequent operation will be discharged. Car alarm can be incorrectly installed, which also leads to the discharge of the battery. A qualified electrician can quickly determine the current leakage place after dismantling the anti-theft device. If the reason is in the alarm itself, it should be replaced with a new one. It would be nice to use the repair services of a faulty alarm system, which is offered in car services, but it is necessary to do this only in proven workshops to avoid further problems (for example, frequency failure, which leads to a signal loss).
6
Tuning the car tuning, car enthusiasts sometimes do not think about the fact that they overload electrical dishes. Overloaded by the operation of the automagnetic, subwoofer, amplifier, speakers, TV, etc., the generator does not cope with the supply of electricity, as a result of which the battery is discharged. In the car service, the auto electrician can calculate the load that one or another generator is capable of withstanding. You may need to install a higher power generator or an additional battery.
7
The battery is often discharged due to the generator breakdown. It happens even on a new car. The generator breakdown detects only the diagnostics of the automotive wiring. The main causes of the generator fault: the failure of the voltage regulator relay, the wear of graphite brushes, breakdown bearing and diode bridge. The generator can be repaired or buy new.
If the battery suddenly discharged on the road, it will be able to charge it from the battery of another car, connecting them with special wires ("crocodiles"). The battery does not charge 100%, but the charge is enough to get to the car service.
