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 2016-2021 Honda Civic 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 2016-2021 Honda Civic 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 2016-2021 Honda Civic? Engine bay, driver side. ### Does a 2016-2021 Honda Civic need the battery registered after replacement? All 10th-gen Civics. 2.0L, 1.5T, Si, and Type R, use a Group 51R battery (factory ~410 CCA; common replacements 425-500 CCA). No start-stop system, so a flooded battery is fine; keep the hold-down bracket, the 51R is small and tips easily. ## Sources - [Motivx Tools, 2016-2018 Civic oil change guide (capacities by engine)](https://www.motivxtools.com/pages/2016-2017-2018-honda-civic-oil-change-guide) - [AMSOIL product application guide, 2017 Civic 1.5L L15B7](https://www.amsoil.com/lookup/auto-and-light-truck/2017/honda/civic/1-5l-4-cyl-engine-code-l15b7-8-turbo/) - [Honda parts, 17220-5AA-A00 (1.5T) and 17220-5BA-A00 (2.0L) air filters](https://honda.oempartsonline.com/oem-parts/honda-air-filter-172205aaa00) - [Honda parts, 12290-59B-003 spark plug (NGK ILZKAR8H8S), 2016-2021 Civic 1.5T](https://honda.oempartsonline.com/oem-parts/honda-spark-plug-1229059b003) - [Honda parts, 15400-PLM-A02 oil filter](https://honda.oempartsonline.com/oem-parts/honda-oil-filter-15400plma02) - [NHTSA recall 20V-314, Denso fuel pump (Part 573 report)](https://static.nhtsa.gov/odi/rcl/2020/RCLRPT-20V314-4001.PDF) - [NHTSA recall 23V-858, expanded fuel pump recall (Part 573 report)](https://static.nhtsa.gov/odi/rcl/2023/RCLRPT-23V858-1287.PDF) - [NHTSA, 2016 Civic piston pin snap ring recall 16V-074 / SB 16-017](https://static.nhtsa.gov/odi/rcl/2016/RCMN-16V074-0449.pdf) - [Honda TSB 19-091, AC condenser 10-year warranty extension (NHTSA copy)](https://static.nhtsa.gov/odi/tsbs/2019/MC-10163799-0001.pdf) - [WardsAuto, Honda extends warranty for 1.5L oil dilution (Civic/CR-V)](https://www.wardsauto.com/news/archive-wards-honda-extends-warranty-to-address-1-5l-gas-oil-dilution-problem/793295/) - [TirePressure.org, 2017 Honda Civic placard pressures by trim](https://tirepressure.org/honda/civic/2017) - [fueleconomy.gov, 2017 Honda Civic EPA ratings](https://www.fueleconomy.gov/feg/bymodel/2017_Honda_Civic.shtml) - [CivicX forum, brake rotor/caliper dimensions by trim](https://www.civicx.com/forum/threads/brake-info-thread.62520/) - [Interstate Batteries, 2017/2019 Civic Group 51R fitment](https://www.interstatebatteries.com/products/m-51r/2017-honda-civic-l415l-standard) ## Other Honda Civic generations - [2022-2025 Honda Civic battery](https://whichcarparts.com/cars/honda/civic/2022-2025/battery) - [2012-2015 Honda Civic battery](https://whichcarparts.com/cars/honda/civic/2012-2015/battery) Or [compare all generations](https://whichcarparts.com/cars/honda/civic/battery). ## More for the 2016-2021 Honda Civic - [Oil & filter](https://whichcarparts.com/cars/honda/civic/2016-2021/oil) - [Tires & wheels](https://whichcarparts.com/cars/honda/civic/2016-2021/tires) - [Wiper blades](https://whichcarparts.com/cars/honda/civic/2016-2021/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/honda/civic/2016-2021/filters) - [Bulbs](https://whichcarparts.com/cars/honda/civic/2016-2021/bulbs) - [Brakes](https://whichcarparts.com/cars/honda/civic/2016-2021/brakes) - [Fluids](https://whichcarparts.com/cars/honda/civic/2016-2021/fluids) - [Service schedule](https://whichcarparts.com/cars/honda/civic/2016-2021/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/honda/civic/2016-2021/common-problems) - [Oil light reset](https://whichcarparts.com/cars/honda/civic/2016-2021/oil-reset) - [Key fob battery](https://whichcarparts.com/cars/honda/civic/2016-2021/key-fob-battery) - [Specs](https://whichcarparts.com/cars/honda/civic/2016-2021/specs) Specifications vary with engine option, production date, and market.
