From O'Reilly Auto Parts' catalog — the store we buy your battery from (checked on a 2006 3.6L and a 2011 3.6L CTS). Some engines and trims differ, so we confirm the exact battery for your CTS when you book and show you the price before we install it.
Where the battery is & what the swap involves
2003–2007 Cadillac CTS
Where it is: Not under the hood — it's in the trunk, under the floor panel.
2008–2013 Cadillac CTS
Where it is: Under the hood.
How it works
Book online and pay the service fee — your card is saved. We head to your CTS, 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.
Cadillac CTS
Straight answers.
By O'Reilly's catalog, the Cadillac CTS takes — 2003–2007: Group 75 or Group 101 (540–690 CCA); 2008–2013: Group 48 (660–800 CCA). Engines can differ, so we confirm the exact battery for your CTS when you book, and you see the price before we install it.
The catalog lists regular batteries for every Cadillac CTS we cover; an AGM is an upgrade some owners choose for short trips and Oklahoma heat. For 2008–2013, regular and AGM both fit — we'll match what your CTS came with unless you ask for the upgrade.
2003–2007: Not under the hood — it's in the trunk, under the floor panel. 2008–2013: Under the hood. Wherever it is, we swap it where the car is parked.
