Expensive repair due to a single mistake that drivers are not even aware of.

The wrong attitude towards a car battery can have serious consequences for drivers, including costly repairs and even the immobilization of the vehicle. An expert from the portal ampercar.com emphasized the importance of correctly disconnecting the terminals to prevent damage to the electronics.

In modern cars, especially in the premium class, such as Audi and BMW, disconnecting the battery can be perceived by the system as an attempted theft. This can lead to the blocking of the engine management system, the recovery of which is only possible through an official dealer using special software.

In budget foreign cars, disconnecting the battery can lead to the resetting of the multimedia system settings.

The key point is the order of disconnection of the terminals. The expert stressed that it is necessary to start with the 'negative' wire. This is related to the fact that the metal key is a conductor of electric current. 'If you accidentally touch the body with the key, a short circuit may occur, which can damage the vital electronic systems of the car. In the worst case, this may lead to a failure of the management system,' the specialist explained.

After disconnecting the 'negative' wire, the risk of short circuit is absent. For additional safety, it is recommended to use an insulation cap. The installation of the battery is carried out in reverse order: first the 'positive' wire is connected, and then the 'negative'. After completing the work, it is necessary to restore the settings of the infotainment center. Following these simple rules will help avoid problems and ensure the reliable operation of the car.
