Honda Pilot 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 Pilot 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 Pilot take?

BCI group 48 (H6). 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.

Does the Honda Pilot need an AGM battery?

Yes. This vehicle requires AGM, not flooded. A flooded battery in a start-stop system is cycled far harder than it is designed for and fails early.

Where is the battery on a Honda Pilot?

Engine bay, driver side.

Does a Honda Pilot need the battery registered after replacement?

Every 4th-gen Pilot trim uses idle-stop and requires the AGM Group 48/H6 battery, no flooded option like the LX/EX of the previous generation.
