Honda CR-V Battery Size (BCI Group and CCA)

Each row links to the full specification for that generation, including trim-by-trim breakdowns and the part numbers. Where engines within a generation differ, that page separates them.

The battery on a Honda CR-V is set by its generation, not its model year, so each generation has one page carrying the complete figures, part numbers and fitment notes for every year it covers.

What size battery does a Honda CR-V take?

BCI group 47 (H5/L2), 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 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 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 Honda CR-V?

Engine bay, driver side.

Does a Honda CR-V need the battery registered after replacement?

Gas (1.5T) models finally moved off the little 51R to a DIN-format Group 47 (H5) battery; parts stores list 47/H5 for 2023+ gas CR-Vs, with AGM H5 as a popular upgrade. Hybrids differ. They keep a Group 51R 12V under the hood (see hybrid engine entry). Confirm your battery's stamped group before buying.
