What to know about the S8 battery
An S8 has more electronics awake at any moment than most cars have in total, so it is unforgiving about battery quality. It wants a full-size AGM, registered correctly. On chauffeur-driven cars that idle with the cabin running, we see batteries worn out by cycling rather than by age.
As an S or RS model, the S8 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.

Where is the battery on an Audi S8?
The A8 battery is under the luggage compartment floor, beneath the spare wheel area and a metal bracket held by four bolts. Some versions have a second, smaller auxiliary battery.

Audi S8 battery questions
Short answers. Anything else — WhatsApp us.
Does the S8 have two batteries?
Many do in some form. All have the main 12V AGM in the boot. D5 mild hybrids add a 48V lithium-ion battery, and some versions carry a small auxiliary battery. We test what is fitted and replace only the 12V units.
Is it safe to replace an S8 battery outside a workshop?
Yes, when it is done with a memory keeper and coded afterwards. That is how we do every one. The job needs space behind the car and about 45 minutes.
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.
