The A6 executive sedan pairs AGM batteries with mild-hybrid systems on recent versions.
Pick the model year to see its generation. It narrows things down — it doesn’t settle the exact battery on its own.
Choose a year to see which generation it belongs to and what that means for the battery.

We don’t publish battery specifications we haven’t verified. Different engines and equipment can require different batteries, so the exact match is confirmed against your vehicle and the battery currently fitted.
These symptoms can also come from charging faults, parasitic drain, cables or the starter. A battery and charging test tells them apart.
Generation, engine and the fitted battery label are checked against the replacement.
A memory saver is connected where practical.
Covers and heat shields are removed and kept for refitting.
Negative first off, last on. Terminals cleaned, hold-down tightened, vent tube refitted where present.
Many Audi models with battery energy management should have the new battery adapted using diagnostic equipment, including battery serial or type details.
Starting and charging voltages are verified before we leave.
Technologies recorded for this model’s generations. The right one for your car depends on its exact specification.
Absorbent Glass Mat
A vehicle designed for AGM should be fitted with AGM. A flooded or EFB battery in its place is likely to wear out quickly and may trigger charging-system faults.
About AGM →Enhanced Flooded Battery
EFB can often replace a conventional battery, and AGM can often replace EFB — but EFB should not replace AGM. The vehicle may also need to be told which type is fitted.
About EFB →It depends on the generation, engine and equipment. Use the year selector above to narrow down the generation, then send us your vehicle details and a photo of the current battery label — we confirm the exact match before fitting.
Yes for the 12V battery, following the vehicle’s specification.
Send the year and a photo of the current battery. We confirm the match for your A6 and fit it where you park.
