Where the battery is & what the swap involves

2001–2003 Audi S8

Where it is: Not under the hood — it's in the trunk, under the floor panel.

After the swap: Newer Audis and Volkswagens may need the new battery coded to the car's computer — we take care of it.

How it works

Book online and pay the service fee — your card is saved. We head to your S8, test the old battery, take it to the closest O'Reilly for the core exchange and buy the right new one at the store's walk-in price. Back at your car we charge the battery plus sales tax to your saved card, install it, test the charging system and email your receipt. Installation labor is covered for 90 days.

Audi S8

Straight answers.

By O'Reilly's catalog, the Audi S8 takes — 2001–2003: Group 49 (825–950 CCA). Engines can differ, so we confirm the exact battery for your S8 when you book, and you see the price before we install it.

The catalog lists regular batteries for every Audi S8 we cover; an AGM is an upgrade some owners choose for short trips and Oklahoma heat. For 2001–2003, regular and AGM both fit — we'll match what your S8 came with unless you ask for the upgrade.

Not under the hood — it's in the trunk, under the floor panel. Wherever it is, we swap it where the car is parked.
