BCI group 35. 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 Subaru Forester need an AGM battery? The factory battery is an EFB type. Match the type when you replace it. ### Where is the battery on a Subaru Forester? Engine bay, driver side. ### Does a Subaru Forester need the battery registered after replacement? 12V accessory battery only, the Hybrid's separate lithium-ion traction battery pack is a sealed, high-voltage component serviced only by trained technicians. Non-hybrid trims continue with an EFB Group 35 supporting standard start-stop. ## Sources - [Wikipedia, Subaru Forester generations (SL)](https://en.wikipedia.org/wiki/Subaru_Forester) - [Subaru Media, Subaru debuts all-new 2025 Forester SUV (press release)](https://media.subaru.com/pressrelease/2123/1/subaru-debuts-all-new-2025-forester-suv-new) - [Car and Driver, Tested: 2025 Subaru Forester Hybrid (specs, mpg, curb weight, tire size)](https://www.caranddriver.com/reviews/a64352235/2025-subaru-forester-hybrid-drive/) - [AMSOIL lookup, 2025 Forester 2.5L FB25D oil spec/capacity (0W-16, 4.6 qt)](https://www.amsoil.com/lookup/auto-and-light-truck/2025/subaru/forester/2-5l-4-cyl-engine-code-fb25d-1/) - [sportsubarusouth.com, Subaru Forester oil type by model year (2025, incl.
