From O'Reilly Auto Parts' catalog — the store we buy your battery from (checked on a 2009 3.5L and a 2016 3.6L 300). Some engines and trims differ, so we confirm the exact battery for your 300 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 300, 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.
Chrysler 300
Straight answers.
By O'Reilly's catalog, the Chrysler 300 takes — 2005–2010: Group 94R (730–880 CCA); 2011–2023: Group 94R (730–880 CCA). Engines can differ, so we confirm the exact battery for your 300 when you book, and you see the price before we install it.
The catalog lists regular batteries for every Chrysler 300 we cover; an AGM is an upgrade some owners choose for short trips and Oklahoma heat. For 2005–2010, 2011–2023, regular and AGM both fit — we'll match what your 300 came with unless you ask for the upgrade.
Not under the hood — it's in the trunk, under the floor panel. The posts under the hood are only for jump-starting. Wherever it is, we swap it where the car is parked.
