Which battery your A3 takes
| Model years | Battery size | Cold-cranking amps | Type |
|---|---|---|---|
| 2006–2013 | Group 48 | 615–800 CCA | Regular or AGM |
| 2015–2020 | Group 48 | 615–800 CCA | Regular or AGM |
From O'Reilly Auto Parts' catalog — the store we buy your battery from (checked on a 2010 2.0L Turbo and a 2017 2.0L Turbo A3). Some engines and trims differ, so we confirm the exact battery for your A3 when you book and show you the price before we install it.
We replace batteries in gas and diesel Audi A3s — not the A3 e-tron plug-in hybrid.

How it works
Book online and pay the service fee — your card is saved. We head to your A3, 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 A3
Straight answers.
By O'Reilly's catalog, the Audi A3 takes — 2006–2013: Group 48 (615–800 CCA); 2015–2020: Group 48 (615–800 CCA). Engines can differ, so we confirm the exact battery for your A3 when you book, and you see the price before we install it.
The catalog lists regular batteries for every Audi A3 we cover; an AGM is an upgrade some owners choose for short trips and Oklahoma heat. For 2006–2013, 2015–2020, regular and AGM both fit — we'll match what your A3 came with unless you ask for the upgrade.
Under the hood.
Every gas and diesel Audi A3 — but not the A3 e-tron plug-in hybrid. We don't service hybrid or electric vehicle batteries.
