Which battery your RX takes
| Model years | Battery size | Cold-cranking amps | Type |
|---|---|---|---|
| 2010–2015 | Group 35 or Group 24F/24R | 600–720 CCA | Regular or AGM |

From O'Reilly Auto Parts' catalog — the store we buy your battery from (checked on a 2013 3.5L, a 2018 3.5L and a 2023 2.4L Turbo RX). Some engines and trims differ, so we confirm the exact battery for your RX when you book and show you the price before we install it.
We replace batteries in gas and diesel Lexus RXs — not the RX 450h and RX 500h hybrids.

How it works
Book online and pay the service fee — your card is saved. We head to your RX, 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.
Lexus RX
Straight answers.
By O'Reilly's catalog, the Lexus RX takes — 2010–2015: Group 35 or Group 24F/24R (600–720 CCA); 2016–2022: Group 35 or Group 24F/24R (600–720 CCA); 2023–present: Group 48 (730–800 CCA). Engines can differ, so we confirm the exact battery for your RX when you book, and you see the price before we install it.
The catalog lists regular batteries for every Lexus RX we cover; an AGM is an upgrade some owners choose for short trips and Oklahoma heat. For 2010–2015, 2016–2022, 2023–present, regular and AGM both fit — we'll match what your RX came with unless you ask for the upgrade.
Under the hood.
Every gas and diesel Lexus RX — but not the RX 450h and RX 500h hybrids. We don't service hybrid or electric vehicle batteries.
