BCI group 48 (H6) AGM. Group size is a physical dimension and terminal-position standard, so a battery from a different group may not clamp down or may put the terminals on the wrong side. ### Does the Hyundai Sonata need an AGM battery? Yes. This vehicle requires AGM, not flooded. A flooded battery in a start-stop system is cycled far harder than it is designed for and fails early. ### Where is the battery on a Hyundai Sonata? Engine bay, driver side. ### Does a Hyundai Sonata need the battery registered after replacement? Start-stop is standard across the DN8 lineup, requiring an AGM battery; Group 48 (H6) is the most commonly reported OEM-equivalent fit. Confirm against your VIN before ordering. ## Sources - [Wikipedia, Hyundai Smartstream engine family (G1.6T, G1.6T Hybrid, displacement/output data)](https://en.wikipedia.org/wiki/Hyundai_Smartstream_engine) - [AMSoil lookup, 2022 Sonata 2.5L oil viscosity/capacity](https://www.amsoil.com/lookup/auto-and-light-truck/2022/hyundai/sonata/2-5l-4-cyl-engine-code-a-a/) - [Costa Oils, 2023 Sonata 2.5L Turbo (N Line) oil guide](https://costaoils.com/2023-hyundai-sonata-2-5l-turbo-oil-change-guide-2/) - [Hyundai Forums, N Line owner's manual 0W-30 vs. 0W-20 cap discussion](https://www.hyundai-forums.com/threads/0w-20-oil-only-one-listed.671641/) - [Goodyear, 2024 Sonata factory tire fitments by trim](https://www.goodyear.com/en-us/vehicles/Hyundai/Sonata/2024) - [Headquarter Hyundai, 2020 Sonata fuel tank capacity and EPA mpg](https://www.headquarterhyundai.com/research/2020-hyundai-sonata-mpg/) - [US News, 2021 Sonata Limited 1.6T engine specs](https://cars.usnews.com/cars-trucks/hyundai/sonata/2021/specs/sonata-limited-1-6t-416162) - [Go-Parts, 2021-2024 Hyundai/Kia 2.5L Smartstream (G4KN) oil dilution/piston-ring notes](https://www.go-parts.com/garage/engine-complete-assembly-kia-sorento-hyundai-santa-fe-hyundai-sonata-2021-2024) ## Find your exact Sonata - [2025](https://whichcarparts.com/cars/hyundai/sonata/2025) - [2024](https://whichcarparts.com/cars/hyundai/sonata/2024) - [2023](https://whichcarparts.com/cars/hyundai/sonata/2023) - [2022](https://whichcarparts.com/cars/hyundai/sonata/2022) - [2021](https://whichcarparts.com/cars/hyundai/sonata/2021) - [2020](https://whichcarparts.com/cars/hyundai/sonata/2020) - [2019](https://whichcarparts.com/cars/hyundai/sonata/2019) - [2018](https://whichcarparts.com/cars/hyundai/sonata/2018) - [2017](https://whichcarparts.com/cars/hyundai/sonata/2017) - [2016](https://whichcarparts.com/cars/hyundai/sonata/2016) - [2015](https://whichcarparts.com/cars/hyundai/sonata/2015) - [2014](https://whichcarparts.com/cars/hyundai/sonata/2014) - [2013](https://whichcarparts.com/cars/hyundai/sonata/2013) - [2012](https://whichcarparts.com/cars/hyundai/sonata/2012) - [2011](https://whichcarparts.com/cars/hyundai/sonata/2011) More Hyundai Sonata guides: - [Oil & filter](https://whichcarparts.com/cars/hyundai/sonata/oil) - [Tires & wheels](https://whichcarparts.com/cars/hyundai/sonata/tires) - [Wiper blades](https://whichcarparts.com/cars/hyundai/sonata/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/hyundai/sonata/filters) - [Bulbs](https://whichcarparts.com/cars/hyundai/sonata/bulbs) - [Brakes](https://whichcarparts.com/cars/hyundai/sonata/brakes) - [Fluids](https://whichcarparts.com/cars/hyundai/sonata/fluids) - [Service schedule](https://whichcarparts.com/cars/hyundai/sonata/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/hyundai/sonata/common-problems) - [Oil light reset](https://whichcarparts.com/cars/hyundai/sonata/oil-reset) - [Key fob battery](https://whichcarparts.com/cars/hyundai/sonata/key-fob-battery) - [Specs](https://whichcarparts.com/cars/hyundai/sonata/specs) Specifications vary with engine option, production date, and market.
