BCI group 35 (gas trims); H5 AGM on trims with idle Stop & Go, rated at 500 cold cranking amps from the factory. 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. ### How many CCA does a Hyundai Elantra need? At least 500 CCA. Going higher is harmless and helps in cold climates; going lower is how a vehicle that started fine in October stops starting in January. ### Does the Hyundai Elantra need an AGM battery? The factory battery is a conventional flooded type. AGM is a valid upgrade, but never downgrade from AGM to flooded. ### Where is the battery on a Hyundai Elantra? Engine bay, driver side (gas); trunk (hybrid). ### Does a Hyundai Elantra need the battery registered after replacement? Base gas trims use a flooded Group 35 battery. Trims equipped with Hyundai's idle Stop & Go feature require an AGM (commonly a Group H5) to survive the frequent stop/restart cycling. Check your trim before replacing with flooded. Hybrid uses a separate trunk-mounted 12V AGM (see hybrid engine entry). ## Sources - [Ontario Hyundai, Elantra oil type & capacity by model year (2021-2026 engines)](https://www.ontariohyundai.com/service/service-and-parts-tips/hyundai-elantra-oil-type/) - [AMSOIL lookup, 2022 Elantra 2.0L Smartstream MPI oil spec/capacity](https://www.amsoil.com/lookup/auto-and-light-truck/2022/hyundai/elantra/2-0l-4-cyl-engine-code-g-g/) - [AMSOIL lookup, 2022 Elantra 1.6L Hybrid oil spec/capacity](https://www.amsoil.com/lookup/auto-and-light-truck/2022/hyundai/elantra/1-6l-4-cyl-engine-code-c-c/) - [AMSOIL lookup, 2022 Elantra N 2.0L Turbo oil spec/capacity](https://www.amsoil.com/lookup/auto-and-light-truck/2022/hyundai/elantra-n/2-0l-4-cyl-engine-code-h-h-turbo/) - [OilShop.ca, 2025 Elantra N oil type, capacity, filter](https://www.oilshop.ca/blog/2025-hyundai-elantra-n-oil-type-oil-filter-oil-change-interval-and-oil-capacity-information) - [Konig Wheels fit check, Elantra N factory wheel/tire fitment (245/35R19, 5x114.3)](https://konigwheels.com/blogs/fit-check/hyundai-elantra-n-fit-check) - [Michelin USA, Elantra N tire sizes and pressures](https://www.michelinman.com/auto/manufacturers/hyundai/elantra-n) - [Paragon/EBay, Elantra N 360mm front brake rotor OE diameter](https://paragonbrakes.com/paragon-2-piece-rotors-front-pair-360x30mm-hyundai-elantra-n/) - [NHTSA recall 22V-123/22V-218/22V-354, seat belt pretensioner explosion risk](https://api.nhtsa.gov/recalls/recallsByVehicle?make=hyundai&model=elantra&modelYear=2022) - [NHTSA recall 24V-879, rearview camera failure](https://api.nhtsa.gov/recalls/recallsByVehicle?make=hyundai&model=elantra&modelYear=2022) - [NHTSA recall 24V-308, EGR valve electrical short](https://api.nhtsa.gov/recalls/recallsByVehicle?make=hyundai&model=elantra&modelYear=2024) - [fueleconomy.gov, 2022 Elantra EPA ratings (all trims incl.
