Volkswagen Workshop Service and Repair Manuals

The battery is one of the most important electrical components in a vehicle. A trouble free battery has a great influence on customer satisfaction. To ensure long use of the battery, the battery must be checked, serviced and maintained as per the instructions in this Manual.

Apart from starting, the battery has other tasks: It acts as a buffer and supplies electrical energy to the complete vehicle electrical system.

The battery has also gone through a technical change and further development will continue. But today it is not possible, for reasons of physical/chemical limits, to have a completely maintenance free battery in a vehicle.
