►Audi RS 3  ►Service and care  ►Checking and topping up fluids  ◀Battery
A replacement battery must have the same specifications as the original equipment battery.
Your vehicle is equipped with an intelligent power management system to control the distribution of electrical energy ►Link. The power management function ensures that the battery is charged much more efficiently than on vehicles without a power management system. For this additional power to be available after replacing the battery, we recommend that the replacement battery used is of the same make and type as the original-equipment battery. The battery must be encoded in the control unit for power management. This has to be done by a qualified workshop.
A replacement battery must have the same capacity, voltage (12 V) and current rating. It must also have the same dimensions as the original, factory-fitted battery and have sealed caps. The battery must comply with the standards TL 825 06 (dated April 2008 or later) and VW 7 50 73 (April 2010 or later).
The battery (in the luggage compartment) should be changed by a qualified workshop. Please observe the notes on the battery cover.
Caution!
  • Vehicles with e.g. a start/stop system* are equipped with a special deep cycle battery (e.g. AGM type). The on-board electronic systems may develop problems if you fit a different type of battery. For this reason, if you need to replace the vehicle battery, make sure that the specifications of the new battery match the original exactly.
  • Make sure that the vent hose is always attached to the original opening on the side of the battery. Gases or battery acid can otherwise escape and possibly cause damage.
  • The battery holder and clamps must always be correctly secured.
  • Before starting any work on the battery, always observe the warnings listed under ►Link.
For the sake of the environment
Batteries contain toxic substances including sulphuric acid and lead. They must be disposed of appropriately and must not be put together with ordinary household waste. Make sure the battery removed from the vehicle cannot tip over. Otherwise, sulphuric acid could escape.
