What size battery does a 2022–2025 Honda Civic 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 2022–2025 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.

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 2022–2025 Honda Civic?

Engine bay, driver side.
