The driver may have to disconnect the car battery for many reasons, including because the battery needs charging, or to change the battery due to its damage or the end of its life span. ?

The experts answered this question and said, that separating the battery from the car and reinstalling it or replacing it with a new one does not affect the programming of the car’s computer or any system and does not affect the work of the sensors in the car.

There is also a prevailing belief that if the driver wants to change the battery and replace it with a new one, the engine must be left running to preserve the computer programming, and this is a wrong belief as well. Rather, it is preferable to shut down the engine when changing the battery, and this will not affect the computer programming.

The reason for this is that the computer has two memories, the first includes programming the entire car, such as “gasoline morphology, gear shift timing, etc., and can never be erased except by professional people, and the second memory is instantaneous and can be erased because it is not as important as the first memory because it contains heat Weather, time, and radio, for example.
