 Audi A1   General maintenance   Checking and topping up fluids  Battery
A replacement battery must have the same specifications as the original equipment battery.
Depending on the type of engine, the battery is installed in one of the following places:
  • In the spare wheel well under the floor panel in the luggage compartment, or
  • At the front left-hand side of the engine compartment (as seen in direction of travel)
We recommend having the battery changed by an Audi dealer or qualified workshop.
Your Audi A1 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 Audi A1s 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. After changing the battery, the power management system must be initialised by a qualified workshop to ensure that the replacement battery is charged to an optimum level.
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 October 2006 or later) and VW 7 50 73 (August 2001 or later).
  • Audi A1s with e.g. a start/stop system* are equipped with a special deep cycle battery (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 Audi A1 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 Audi A1 cannot tip over. Otherwise, sulphuric acid could escape.
