From O'Reilly Auto Parts' catalog — the store we buy your battery from (checked on a 2012 3.5L and a 2017 2.0L Turbo C-Class). Some engines and trims differ, so we confirm the exact battery for your C-Class 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 C-Class, 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.
Mercedes-Benz C-Class
Straight answers.
By O'Reilly's catalog, the Mercedes-Benz C-Class takes — 2008–2014: Group 94R or Group 48 (720–880 CCA); 2015–2021: Group 48 or Group 94R (760–880 CCA). Engines can differ, so we confirm the exact battery for your C-Class when you book, and you see the price before we install it.
For 2015–2021 Mercedes-Benz C-Classs, 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 2008–2014, regular and AGM both fit — we'll match what your C-Class came with unless you ask for the upgrade.
2008–2014: Not under the hood — it's in the trunk. 2015–2021: Under the hood, under a cover. Wherever it is, we swap it where the car is parked.
