From O'Reilly Auto Parts' catalog — the store we buy your battery from (checked on a 2006 4.2L and a 2022 1.3L Turbo TrailBlazer). Some engines and trims differ, so we confirm the exact battery for your TrailBlazer 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 TrailBlazer, 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.
Chevrolet TrailBlazer
Straight answers.
By O'Reilly's catalog, the Chevrolet TrailBlazer takes — 2002–2009: Group 78 (600–800 CCA); 2021–present: Group 48 (760–800 CCA). Engines can differ, so we confirm the exact battery for your TrailBlazer when you book, and you see the price before we install it.
For 2021–present Chevrolet TrailBlazers, the parts store's catalog only lists AGM batteries — those usually came with one from the factory, often for auto start-stop or heavier electrical loads, and we put the same type back. For 2002–2009, regular and AGM both fit — we'll match what your TrailBlazer came with unless you ask for the upgrade.
