Which battery your Optima takes
| Model years | Battery size | Cold-cranking amps | Type |
|---|---|---|---|
| 2011–2015 | Group 124R or Group 35 | 700–720 CCA | Regular or AGM |
| 2016–2020 | Group 94R | 800–880 CCA | AGM |
From O'Reilly Auto Parts' catalog — the store we buy your battery from (checked on a 2013 2.4L and a 2018 2.4L Optima). Some engines and trims differ, so we confirm the exact battery for your Optima when you book and show you the price before we install it.
We replace batteries in gas and diesel Kia Optimas — not the Optima Hybrid.

How it works
Book online and pay the service fee — your card is saved. We head to your Optima, 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.
Kia Optima
Straight answers.
By O'Reilly's catalog, the Kia Optima takes — 2011–2015: Group 124R or Group 35 (700–720 CCA); 2016–2020: Group 94R (800–880 CCA). Engines can differ, so we confirm the exact battery for your Optima when you book, and you see the price before we install it.
For 2016–2020 Kia Optimas, 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 2011–2015, regular and AGM both fit — we'll match what your Optima came with unless you ask for the upgrade.
Under the hood.
Every gas and diesel Kia Optima — but not the Optima Hybrid. We don't service hybrid or electric vehicle batteries.
