Self Study Program 234 – Vehicle batteries Fundamentals and handling

VAG SSP 234. To enable correct handling of batteries for service and maintenance, a degree of basic knowledge is  necessary, which will be provided in this self-study programme.

The battery is one of the most important electrical components in the vehicle. A perfectly functioning battery contributes significantly towards customer satisfaction.

In addition to the engine starting function, the vehicle battery also has the task of storing electrical energy for the whole onboard electrical system in the vehicle.

The vehicle battery acts as an accumulator. This means it can accept electrical energy for purposes of storage and make it available for other uses at a later stage, depending on the demand.
