What size battery does a 2019–2025 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 2019–2025 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 2019–2025 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 2019–2025 Nissan Altima?

Engine bay, driver side.

Does a 2019–2025 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.
