What to know about the S4 battery
A boot-mounted battery lives a cooler life than one beside the engine, so a S4 battery often outlasts those in smaller Audis. The catch is access. When it dies with the boot shut, you jump the car from the posts under the bonnet, not from the battery itself.
As an S or RS model, the S4 runs bigger cooling fans, pumps and audio than the standard car, so it should get the AGM battery at the upper end of the capacity range, not the cheapest one that fits.
Battery brands that suit the S4
These are the brands we normally recommend for this model, in the type and size it takes.
Where is the battery on an Audi S4?
On B8 and B9 cars the battery is usually in the luggage compartment under the floor panel, beside the spare wheel well. Older B6 and B7 cars have it under the bonnet near the windscreen. We confirm by model year.

- Jump-start posts are under the bonnet, not in the boot
- The vent tube must be reconnected on a boot-mounted battery
- Older shops skip the coding, which shortens the new battery's life
Signs your S4 battery is on its way out
- Start-stop stops working or shows as unavailable
- The engine turns over more slowly on the first start of the day
- "Low battery" or "Electrical system" messages in the instrument cluster
- MMI or interior lights switch off sooner than they used to
- The battery is more than two UAE summers old
Audi S4 battery questions
Short answers. Anything else — WhatsApp us.
How do I open the boot of my S4 with a dead battery?
Use the metal key blade inside the fob to open the driver's door, then power the car from the jump posts under the bonnet. Once it has power the boot release works. Our technician does this as a matter of routine.
Does the S4 need an AGM battery?
If it has start-stop or a factory AGM label, yes. Most B8.5 and all B9 cars do. Older cars without start-stop can take a quality calcium battery of the right size.
Does an Audi need battery coding after replacement?
Most Audis built from around 2008 do. The car's energy management has to be told a new battery is fitted, with its capacity and type. We do this on site with a diagnostic tool as part of the fitting.
Which battery does my Audi need, AGM or EFB?
If your Audi has start-stop, it needs AGM or EFB, and most larger models need AGM. We check by model, year and the label on the old battery, then fit the same technology or better.
