## How to know which battery your AUDI A6 C8 takes

The quickest and safest route is to enter your number plate: we identify the exact version, its engine and the battery fitted at the factory, with no room for error.

You can also work it out yourself: find the registration date in the vehicle documents and locate it in the table. If the year overlaps two generations, the body style — hatch, estate or coupé — tells them apart.

Before ordering, inspect your existing battery: its label lists the Ah and the starting amps. The replacement must match or beat both — never fall short — and share the same size and positive terminal side.

## Start-Stop: which battery your A6 C8 needs

If your A6 C8 has Start-Stop, the battery works far harder than usual — hundreds of restarts a day rather than a handful. That calls for EFB or AGM, depending on whether the system is basic or includes regenerative braking. A conventional battery there lasts months and can make the car switch Start-Stop off.

## Frequently asked questions

### Which battery does a AUDI A6 C8 take?
It depends on the generation and engine: there are 19 compatible batteries in total, from 45 to 110 Ah and 330 to 950 A of cold cranking. The best sellers for this model are Car battery Varta E11 12V 74Ah 680A, Car battery Varta E44 12V 77Ah 780A, Start-Stop battery Varta A7 12V 70Ah 760A AGM. With your plate we tell you the exact one in seconds.

### How much does a AUDI A6 C8 battery cost?
Between 46.99 € and 172.14 €, VAT included, depending on capacity and technology (lead-acid, AGM, EFB). Start-Stop versions (AGM or EFB) sit at the top of the range because they withstand many more cycles.

### How do I know which generation my A6 C8 is?
By the registration year: A6 C8 (2018-2025); A6 C8 Avant (2018-2025); A6 Allroad C8 (2018-2025); A6 Allroad C7 (2012-2018); A6 C7 Avant (2011-2019); A6 C7 (2010-2019). If your year falls in the overlap between two generations, tell them apart by body type (hatchback, estate or coupé) or use the plate finder, which settles it with no doubt.

### Can I fit a battery with more amps?
Yes, as long as the dimensions fit the tray and the terminal layout matches. More capacity (Ah) and more cold cranking (A) do not harm the vehicle: the alternator charges it the same and you gain margin in winter. What you must never do is go below the original figures.

### How long does a AUDI A6 C8 battery last?
Between 4 and 6 years in normal use. Start-Stop batteries (AGM/EFB) tend to last slightly less in city driving because of the number of starts, but they are designed for that cycling. If the car sits unused for weeks or you notice slow cranking in the cold, get it checked.
