Have the 48 volt lithium battery
replaced
only by an authorized Audi dealer or authorized
Audi Service Facility. Audi recommends
an authorized Audi dealer or authorized
Audi Service Facility, because
these locations have trained personnel
and the required parts and tools.
Never try to replace the 48 volt lithium battery yourself. The 48 volt lithium battery in this vehicle may only be replaced with a 48 volt lithium battery designed by Audi specifically for this vehicle. Using other 48 volt lithium or lead batteries will result in considerable malfunctions or even total failure of the electrical system.
Never make modifications to the lithium battery. If the lithium battery is open, it must not come into contact with water or other liquids. Liquids may cause short circuits, electric shocks, and burns.

A highly explosive mixture of
gases can form when charging batteries.
WARNING
All work on the batteries must only be performed by an authorized Audi dealer or authorized Audi Service Facility.
- Gases that escape from these batteries can be poisonous or flammable.
- The contents of these batteries can be corrosive.
If any battery contents come into contact with the skin, flush the affected area for at least 15 minutes with clean water. Then wash the affected area with soap. Have the affected area examined by a medical professional.
Note
Applies to: mild hybrid drive system: Components must not be connected to the battery terminals and wires of the 48 volt battery because this increases the risk of damage, for example due to overvoltage.
