Frequently asked questions

It depends on the generation and engine: there are 9 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, Start-Stop battery Varta A7 12V 70Ah 760A AGM, Car battery Varta H3 12V 100Ah 830A. With your plate we tell you the exact one in seconds.
Between 66.95 € and 172.14 €, VAT included, depending on capacity and technology (lead-acid, AGM). Start-Stop versions (AGM or EFB) sit at the top of the range because they withstand many more cycles.
By the registration year: A5 II (2016-2025); A5 Sportback II (2016-2025); A5 Convertible II (2016-2025); A5 Convertible I (2009-2017); A5 I (2007-2017); A5 Sportback I (2007-2017). 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 A5 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.

Another route is the vehicle paperwork: the registration date places you in one of the generations listed. In the overlap years, body style is the detail that separates them.

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 A5 needs

The later A5 generations run Start-Stop, which puts the battery through hundreds of micro-cycles a day. These cars require EFB (basic Start-Stop) or AGM (Start-Stop with regenerative braking): fitting a conventional battery instead cuts service life to a few months and the ECU may disable the function. Rule of thumb: never downgrade from the technology fitted at the factory.
