Frequently asked questions

It depends on the generation and engine: there are 6 compatible batteries in total, from 70 to 110 Ah and 760 to 950 A of cold cranking. The best sellers for this model are Start-Stop battery Varta A7 12V 70Ah 760A AGM, Start-Stop battery Varta A6 12V 80Ah 800A AGM, Car battery Varta G3 12V 95Ah 800A. With your plate we tell you the exact one in seconds.
Between 94.55 € 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: A5 Convertible II (2016-2025); A5 Convertible I (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 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.

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.

As a final check, look at the battery currently fitted: the label shows capacity (Ah) and cold cranking amps (A). Always replace with equal or higher figures, never lower, and keep the same dimensions and terminal layout.

Start-Stop: which battery your A5 needs

If your A5 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.
