From O'Reilly Auto Parts' catalog — the store we buy your battery from (checked on a 2006 1.3L RX-8). Some engines and trims differ, so we confirm the exact battery for your RX-8 when you book and show you the price before we install it.

How it works
Book online and pay the service fee — your card is saved. We head to your RX-8, 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.
Mazda RX-8
Straight answers.
By O'Reilly's catalog, the Mazda RX-8 takes — 2004–2011: Group 35 (640–765 CCA). Engines can differ, so we confirm the exact battery for your RX-8 when you book, and you see the price before we install it.
The catalog lists regular batteries for every Mazda RX-8 we cover; an AGM is an upgrade some owners choose for short trips and Oklahoma heat. For 2004–2011, regular and AGM both fit — we'll match what your RX-8 came with unless you ask for the upgrade.
