From O'Reilly Auto Parts' catalog — the store we buy your battery from (checked on a 2019 2.0L and a 2022 2.0L Elantra). Some engines and trims differ, so we confirm the exact battery for your Elantra when you book and show you the price before we install it.

We replace batteries in gas and diesel Hyundai Elantras — not the Elantra Hybrid.

How it works

Book online and pay the service fee — your card is saved. We head to your Elantra, 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.

Hyundai Elantra

Straight answers.

By O'Reilly's catalog, the Hyundai Elantra takes — 2017–2020: Group 48 (760–800 CCA); 2021–present: Group 47 (650–660 CCA). Engines can differ, so we confirm the exact battery for your Elantra when you book, and you see the price before we install it.

For 2017–2020 Hyundai Elantras, 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 2021–present, regular and AGM both fit — we'll match what your Elantra came with unless you ask for the upgrade.

2017–2020: Under the hood, driver's side. 2021–present: Under the hood (gas models).

Every gas and diesel Hyundai Elantra — but not the Elantra Hybrid. We don't service hybrid or electric vehicle batteries.
