What size battery does a 2023–2025 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 2023–2025 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 2023–2025 Honda Pilot?

Engine bay, driver side.

Does a 2023–2025 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.
