Frequently asked questions

It depends on the generation and engine: there are 8 compatible batteries in total, from 70 to 110 Ah and 680 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.
Between 66.95 € and 172.14 €, VAT included, depending on capacity and technology (AGM, lead-acid). Start-Stop versions (AGM or EFB) sit at the top of the range because they withstand many more cycles.
By the registration year: A4 Allroad B9 (2016-2025); A4 Allroad B8 (2009-2017). 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.
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.
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.

How to know which battery your AUDI A4 Allroad B9 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.

Prefer to do it manually? Check the date of first registration on your V5C and match it against the generation table above. When a year straddles two generations, the body style decides it: five-door hatch, estate or coupé.

One last check: the label on the fitted battery gives you the reference capacity and cold cranking. Match or improve those numbers, and make sure the case size and polarity suit your battery tray.

Start-Stop: which battery your A4 Allroad B9 needs

Start-Stop on the modern A4 Allroad B9 changes the rules: the battery takes hundreds of micro-cycles daily. The correct answer is EFB for basic systems and AGM where braking energy is recovered. Dropping to a conventional battery is the most expensive mistake you can make here.
