Ford Explorer 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 Ford Explorer 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 Ford Explorer take?

BCI group H6 (Group 48), rated at 760 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 Ford Explorer need?

At least 760 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 Ford Explorer 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 Ford Explorer?

Under hood, rear center beneath the cowl/wiper panel. Cowl trim must come off, a 20–30 minute job.

Does a Ford Explorer need the battery registered after replacement?

Auto start-stop requires an AGM replacement (Motorcraft BXT-48H6 style). An H7 (Group 94R) physically fits snugly and is a popular higher-CCA upgrade on STs. After replacement, do a BMS reset (or let the car sit to relearn) so start-stop works properly.
