From O'Reilly Auto Parts' catalog — the store we buy your battery from (checked on a 2001 2.3L Supercharged SLK). Some engines and trims differ, so we confirm the exact battery for your SLK 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 SLK, 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 SLK

Straight answers.

By O'Reilly's catalog, the Mercedes-Benz SLK takes — 1998–2004: Group 48 (750–800 CCA). Engines can differ, so we confirm the exact battery for your SLK when you book, and you see the price before we install it.

The catalog lists regular batteries for every Mercedes-Benz SLK we cover; an AGM is an upgrade some owners choose for short trips and Oklahoma heat. For 1998–2004, regular and AGM both fit — we'll match what your SLK came with unless you ask for the upgrade.
