When the car battery has a problem continuously, one of the first and most common reasons is the corrosion or failure of the connections. After that, there are other reasons such as a connection in the wiring and a problem in the battery charging system. Battery charging problem occurs when the battery consumption is more than the battery charge. Weather conditions and very high or very low ambient temperature can also have a negative effect on the battery. In the following, we will discuss the main reasons for battery drain.
1. Lights on the lights
The first thing you should check if there is a problem with the car battery is that the lights stay on. You may have left the main lights or roof lights on during the night and this can drain the battery. When you leave the car at night and in the dark, check that no lights are left on. In some cars, the lights stay on for a while after the car is turned off and then turn off automatically; But if there is a problem in this system, the lights may stay on and drain the battery.
2. Weakening the battery
If the battery is old or not well maintained, it will hardly hold its charge. Even small problems in the electrical system, such as the audio system, can easily drain a faulty battery while the car is off.
1. Battery correction and burnout
Damage in the battery head connections can prevent the battery from charging, and disconnection of these connections can also cause problems.
1. Connection in the electrical system
The existence of the smallest connection in the car's electrical system can cause a situation called electricity theft. It is very difficult to find such defects; But if you encounter them, it is better to check the dashboard and trunk lights first. These lights may stay on when they are not needed and cause the battery to drain.
