From O'Reilly Auto Parts' catalog — the store we buy your battery from (checked on a 2008 3.6L 911). Some engines and trims differ, so we confirm the exact battery for your 911 when you book and show you the price before we install it.
Where the battery is & what the swap involves

Where it is: Not under the engine lid — it's up front, in the front trunk under a cover.
How it works
Book online and pay the service fee — your card is saved. We head to your 911, 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.
Porsche 911
Straight answers.
By O'Reilly's catalog, the Porsche 911 takes — 2005–2012: Group 94R (800–880 CCA). Engines can differ, so we confirm the exact battery for your 911 when you book, and you see the price before we install it.
For 2005–2012 Porsche 911s, 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.
Not under the engine lid — it's up front, in the front trunk under a cover. Wherever it is, we swap it where the car is parked.
