Fitment, replacement notes, and what to check before you buy. **Quick answer**: The 2017-2022 Honda CR-V uses a Group 51R battery, 410 CCA. ## 2017-2022 Honda CR-V battery specifications (High confidence) | Spec | Value | | --- | --- | | BCI group size | 51R | | Cold cranking amps | 410 CCA | | Battery type | FLOODED | | AGM required | No | | Location | Engine bay, driver side | Note: Factory 51R is rated ~410 CCA; Honda's replacement is 500 CCA and that is what you should buy given this generation's parasitic-drain history. Some owners upsize to a Group 47 (H5) with minor tray modification. It fits with more reserve capacity, but a quality 500 CCA 51R is the drop-in fix. ## 2.0L Hybrid (LFB2 Atkinson + two-motor system) battery (High confidence) | Spec | Value | | --- | --- | | BCI group size | 51R | | Battery type | FLOODED | | Location | Engine bay (12V battery); high-voltage pack under cargo floor | Note: The hybrid's 12V accessory battery is the same small Group 51R as gas models and lives under the hood. It only boots the computers (no cranking), but a dead one still strands the car. The lithium-ion traction pack is separate and warrantied 8 yr/100k (10 yr/150k CARB states). ## Which Honda CR-V model years does this cover? These battery specifications apply to every Honda CR-V built from 2017 through 2022, the 5th generation (RW), compact crossover suv (fwd or real time awd; hybrid awd-only). Nothing in this specification changes between those model years. - [2017 CR-V](https://whichcarparts.com/cars/honda/cr-v/2017) - [2018 CR-V](https://whichcarparts.com/cars/honda/cr-v/2018) - [2019 CR-V](https://whichcarparts.com/cars/honda/cr-v/2019) - [2020 CR-V](https://whichcarparts.com/cars/honda/cr-v/2020) - [2021 CR-V](https://whichcarparts.com/cars/honda/cr-v/2021) - [2022 CR-V](https://whichcarparts.com/cars/honda/cr-v/2022) ## What changed during the 2017-2022 Honda CR-V | Years | What changed | | --- | --- | | 2017 | Generation launch: 1.5T on EX and above, 2.4L on LX; Honda Sensing standard from EX (all trims 2020) | | 2018 | Carries over with minimal changes after the 2017 redesign | | 2019 | Largely unchanged; adds the Platinum White Pearl exterior color as the only notable update ahead of 2020's facelift and hybrid launch | | 2020 | Facelift: 1.5T standard on every gas trim (2.4L dropped), CR-V Hybrid (AWD-only) added, Touring moves to 19-in wheels, Honda Sensing standard | | 2022 | Carryover final year; Special Edition (SE) trim on 17-in wheels | ## 2017-2022 Honda CR-V battery: common questions ### What size battery does a 2017-2022 Honda CR-V take? BCI group 51R, rated at 410 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 2017-2022 Honda CR-V need? At least 410 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 2017-2022 Honda CR-V 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 2017-2022 Honda CR-V? Engine bay, driver side. ### Does a 2017-2022 Honda CR-V need the battery registered after replacement? Factory 51R is rated ~410 CCA; Honda's replacement is 500 CCA and that is what you should buy given this generation's parasitic-drain history. Some owners upsize to a Group 47 (H5) with minor tray modification. It fits with more reserve capacity, but a quality 500 CCA 51R is the drop-in fix. ## Sources - [NOLN TechSpec, 2017 Honda CR-V (oil capacities: 3.7 qt 1.5T / 4.6 qt 2.4L)](https://www.noln.net/home/article/11498439/techspec-2017-honda-cr-v-2017-04-27) - [Honda News, 2017 CR-V press kit specifications (fuel tank, curb weight)](https://hondanews.com/en-US/honda-automobiles/releases/release-d636454c74ac4accb7a1f4dfc6c9bec4-2017-honda-cr-v-press-kit-specifications-features) - [Cars.com, Honda extends warranty on CR-V/Civic for 1.5T oil dilution (TSB 18-114 era)](https://www.cars.com/articles/honda-extends-warranty-on-cr-v-civic-for-1-5-liter-turbo-oil-issue-402938/) - [WardsAuto, Honda 1-year warranty extension to 6 yr/unlimited mi for oil dilution](https://www.wardsauto.com/news/archive-wards-honda-extends-warranty-to-address-1-5l-gas-oil-dilution-problem/793295/) - [ClassAction.org, parasitic draw class action, 2017-2019 CR-V](https://www.classaction.org/news/parasitic-draw-class-action-alleges-2017-2019-honda-cr-v-2016-2019-accord-models-suffer-from-battery-killing-defect) - [Go-Parts garage, 2017-2026 CR-V A/C: TSB A23-040 10-yr compressor shaft seal extension](https://www.go-parts.com/garage/a-c-condenser-honda-cr-v-2017-2026) - [Consumer Reports, Honda/Acura Denso fuel pump recall (2018-2020 CR-V)](https://www.consumerreports.org/cars/car-recalls-defects/acura-honda-cars-minivans-suvs-recalled-fuel-pump-failure-a6454026233/) - [TirePressure.org, 2017 Honda CR-V placard pressures](https://tirepressure.org/honda/cr-v/2017) - [TireSize.com, 2021 CR-V / CR-V Hybrid OE fitments](https://tiresize.com/tires/Honda/CR-V/2021/) - [College Hills Honda, 17220-5AA-A00 air filter (1.5T)](https://www.collegehillshonda.com/product/17220-5AA-A00.html) - [Honda OEM Parts Online, 17220-5PH-A00 air filter (2017-2019 CR-V 2.4L)](https://honda.oempartsonline.com/oem-parts/honda-engine-air-filter-172205pha00) - [fueleconomy.gov, 2020 CR-V / CR-V Hybrid EPA ratings](https://www.fueleconomy.gov/feg/bymodel/2020_Honda_CR-V.shtml) ## Other Honda CR-V generations - [2023-2025 Honda CR-V battery](https://whichcarparts.com/cars/honda/cr-v/2023-2025/battery) - [2012-2016 Honda CR-V battery](https://whichcarparts.com/cars/honda/cr-v/2012-2016/battery) Or [compare all generations](https://whichcarparts.com/cars/honda/cr-v/battery). ## More for the 2017-2022 Honda CR-V - [Oil & filter](https://whichcarparts.com/cars/honda/cr-v/2017-2022/oil) - [Tires & wheels](https://whichcarparts.com/cars/honda/cr-v/2017-2022/tires) - [Wiper blades](https://whichcarparts.com/cars/honda/cr-v/2017-2022/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/honda/cr-v/2017-2022/filters) - [Bulbs](https://whichcarparts.com/cars/honda/cr-v/2017-2022/bulbs) - [Brakes](https://whichcarparts.com/cars/honda/cr-v/2017-2022/brakes) - [Fluids](https://whichcarparts.com/cars/honda/cr-v/2017-2022/fluids) - [Service schedule](https://whichcarparts.com/cars/honda/cr-v/2017-2022/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/honda/cr-v/2017-2022/common-problems) - [Oil light reset](https://whichcarparts.com/cars/honda/cr-v/2017-2022/oil-reset) - [Key fob battery](https://whichcarparts.com/cars/honda/cr-v/2017-2022/key-fob-battery) - [Specs](https://whichcarparts.com/cars/honda/cr-v/2017-2022/specs) Specifications vary with engine option, production date, and market.
