Ram 1500 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 Ram 1500 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 Ram 1500 take?

BCI group H7 (94R / LN4), rated at 730 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 Ram 1500 need?

At least 730 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 Ram 1500 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 Ram 1500?

Engine bay, driver side.

Does a Ram 1500 need the battery registered after replacement?

Non-eTorque trucks ship with a flooded H7 (~730 CCA). eTorque trucks pair an H7 AGM 12V under the hood with a separate air-cooled 48V lithium-ion pack on the cab's rear wall, the 48V pack is not owner-serviceable, and the 12V should be replaced with AGM on eTorque trucks. 800–850 CCA H7 replacements are common upgrades.
