How it works
Book online and pay the service fee — your card is saved. We head to your A4, 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 A4
Straight answers.
By O'Reilly's catalog, the Audi A4 takes — 2009–2016: Group 48 or Group 47 (525–800 CCA); 2017–present: Group 49 or Group 48 (760–950 CCA). Engines can differ, so we confirm the exact battery for your A4 when you book, and you see the price before we install it.
The catalog lists regular batteries for every Audi A4 we cover; an AGM is an upgrade some owners choose for short trips and Oklahoma heat. For 2009–2016, 2017–present, regular and AGM both fit — we'll match what your A4 came with unless you ask for the upgrade.
2009–2016: Under the hood, in the compartment below the windshield (under the cowl cover). 2017–present: In the trunk, under the floor. Wherever it is, we swap it where the car is parked.
