Fitment, replacement notes, and what to check before you buy. **Quick answer**: The 2018-2022 Honda Accord uses a Group 47 (H5/LN2), 1.5T; 48 (H6/LN3), 2.0T battery. ## 2018-2022 Honda Accord battery specifications (High confidence) | Spec | Value | | --- | --- | | BCI group size | 47 (H5/LN2), 1.5T; 48 (H6/LN3), 2.0T | | Battery type | EFB | | AGM required | No | | Location | Engine bay, driver side | Note: The 10th gen switched to DIN-format batteries: 1.5T cars take an H5 (Group 47), 2.0T cars the longer H6 (Group 48). Factory units are EFB; AGM upgrades are popular and fine. An H6 fits many 1.5T trays as a capacity upgrade. Measure first. ## 2.0L Hybrid (LFC i-MMD two-motor, 212 hp combined) battery (Check your manual) | Spec | Value | | --- | --- | | BCI group size | 47 (H5/LN2) 12V, engine bay | | Battery type | EFB | | Location | Engine bay (the high-voltage pack is under the rear seats) | Note: Unlike the 9th-gen hybrid, the 12V battery is under the hood and is the same H5 format as the 1.5T. It never cranks the engine. It just boots the system, so a dead 12V still means a no-start. EFB or AGM replacements both work. ## Which Honda Accord model years does this cover? These battery specifications apply to every Honda Accord built from 2018 through 2022, the 10th generation, mid-size sedan (fastback roofline; coupe discontinued). Nothing in this specification changes between those model years. - [2018 Accord](https://whichcarparts.com/cars/honda/accord/2018) - [2019 Accord](https://whichcarparts.com/cars/honda/accord/2019) - [2020 Accord](https://whichcarparts.com/cars/honda/accord/2020) - [2021 Accord](https://whichcarparts.com/cars/honda/accord/2021) - [2022 Accord](https://whichcarparts.com/cars/honda/accord/2022) ## What changed during the 2018-2022 Honda Accord | Years | What changed | | --- | --- | | 2018 | Generation launch: turbo-only lineup, LED low beams standard, V6 and coupe dropped | | 2021 | Facelift: revised front end, Sport SE trim, hybrid gains steering-wheel deceleration paddles; manual transmission dropped after 2020 | | 2022 | Final year for the 2.0T and 10-speed in the Accord | ## 2018-2022 Honda Accord battery: common questions ### What size battery does a 2018-2022 Honda Accord take?
