Nissan Altima 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 Nissan Altima 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 Nissan Altima take?

BCI group 35, rated at 640 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 Nissan Altima need?

At least 640 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 Nissan Altima 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 Nissan Altima?

Engine bay, driver side.

Does a Nissan Altima need the battery registered after replacement?

Group 35 flooded battery on all trims (Nissan dealer replacement 999M1-NBH35). No start-stop system, so AGM is optional rather than required. A few fitment guides list alternates (24F/47). Group 35 is the standard fit; match your original.
