From O'Reilly Auto Parts' catalog — the store we buy your battery from (checked on a 2007 3.8L and a 2013 3.6L LaCrosse). Some engines and trims differ, so we confirm the exact battery for your LaCrosse when you book and show you the price before we install it.

We replace batteries in gas and diesel Buick LaCrosses — not the eAssist mild-hybrid's separate battery.

Where the battery is & what the swap involves

2005–2009 Buick LaCrosse

Where it is: Under the hood.

2010–2016 Buick LaCrosse

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

How it works

Book online and pay the service fee — your card is saved. We head to your LaCrosse, 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.

Straight answers.

By O'Reilly's catalog, the Buick LaCrosse takes — 2005–2009: Group 34 (750–800 CCA); 2010–2016: Group 48 (615–800 CCA). Engines can differ, so we confirm the exact battery for your LaCrosse when you book, and you see the price before we install it.

The catalog lists regular batteries for every Buick LaCrosse we cover; an AGM is an upgrade some owners choose for short trips and Oklahoma heat. For 2005–2009, 2010–2016, regular and AGM both fit — we'll match what your LaCrosse came with unless you ask for the upgrade.

2005–2009: Under the hood. 2010–2016: Not under the hood — it's in the trunk, under the floor panel. Wherever it is, we swap it where the car is parked.

Every gas and diesel Buick LaCrosse — but not the eAssist mild-hybrid's separate battery. We don't service hybrid or electric vehicle batteries.
