Toyota Corolla 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 Corolla 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 Corolla take?

BCI group H4 (LN1), rated at 470 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 Corolla need?

At least 470 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 Corolla 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 Toyota Corolla?

Engine bay, driver side.

Does a Toyota Corolla need the battery registered after replacement?

The E210 drops the old Group 35 for DIN/EN-format batteries: 1.8L gas and hybrid use H4 (LN1). Toyota TrueStart replacement is rated 470 CCA; 2.0L cars (M20A-FKS) use the larger H5 (LN2), TrueStart-rated 540 CCA. Verified against Toyota's battery application chart (ZRE212/ZWE21# → LN1; MZEA12 → LN2). Check the case size before buying, a Group 35 will not fit the tray correctly.
