Toyota Tacoma 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 Toyota Tacoma 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 Toyota Tacoma take?

BCI group LN3 (DIN H6), many trucks ship with an LN4/H7-size 395LN4-MF, rated at 603 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 Toyota Tacoma need?

At least 603 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 Toyota Tacoma need an AGM battery?

The factory battery is an EFB type. Match the type when you replace it.

Where is the battery on a Toyota Tacoma?

Engine bay.

Does a Toyota Tacoma need the battery registered after replacement?

Owner's-manual spec is an LN3 'Type A' battery, ≥70 Ah, ≥603 CCA (EN rating); many 2024s left the factory with an 80 Ah / 689 CCA LN4 (395LN4-MF). This is a DIN LN-series case, the old Group 24F does NOT fit. Match the case size actually in your truck before buying.
