Audi A4 (B9) 2016-2022 Owner's Manual: Battery

Battery general information

Because of the complex power supply, all work on batteries such as disconnecting, replacing, etc., should only be performed by an authorized Audi dealer or authorized Audi Service Facility.

Multiple batteries with different technologies may be installed in your vehicle:

Not running the vehicle for long periods of time

The battery will gradually drain if the vehicle does not run for long periods of time. To ensure that the vehicle can still be started, the electrical equipment will be limited or switched off. Some convenience functions, such as interior lighting or power seat adjustment, may not be available under certain circumstances. The convenience functions will be available again when you start the engine.

Even when electrical equipment is switched off, the equipment can still drain the battery if the vehicle is not driven for Long periods of time.

Deep draining results in a chemical reaction that destroys the inside of the battery. The battery must be charged every month to prevent this. Contact an authorized Audi dealer or authorized Audi Service Facility for more information.

Winter operation

Cold weather places an especially high load on the 12 volt vehicle battery. This results in reduced starting ability. Have the battery checked by an authorized Audi dealer or authorized Audi Service Facility before cold weather begins.

Replacing the battery

Applies to: 12 volt vehicle battery

All work on the battery must only be performed by an authorized Audi dealer or authorized Audi Service Facility.

The 12 volt vehicle battery was developed based on the installation location and is equipped with safety features. If a 12 volt vehicle battery must be replaced, ask your authorized Audi dealer or authorized Audi Service Facility about the electromagnetic compatibility, size, and the necessary maintenance, power, and safety standards for the new 12 volt vehicle battery. The battery vent of the 12 volt vehicle battery must always be on the negative terminal side. The battery vent on the positive terminal side must always be closed.

Only use a maintenance-free 12 volt vehicle battery that adheres to the TL 825 06 and VW 7 50 73 standards. These standards must be from October 2014 or newer.
