Buying a Group 78 battery

Match the group size (Group 78) and aim for at least 700 CCA - more in cold climates. Confirm your own car's rating on its page below; some trims require AGM. A battery is heavy to ship, so buying in person can win once you count free install and the core-charge refund - but to compare prices and reviews:

Group 78 equivalent sizes

These BCI groups share a near-identical case, so they may fit the same battery tray. “Same terminals” means the +/- posts sit on the same side; reversed terminals (R groups) can leave your cables short.

Frequently asked

How many CCA does a Group 78 battery need?

Group 78 vehicles in our data ship with 600-800 CCA (typically around 700). Match your car's original rating or go higher - aim for the top of that range in cold climates.

Is a Group 78 battery AGM or flooded?

Group 78 is used with standard flooded batteries. AGM is an optional upgrade for longer life in heat and heavy electrical loads, and is safe to fit.

What size is a Group 78 battery?

A BCI Group 78 case measures 260×179×186 mm (L×W×H). Any Group 78 battery uses that footprint, so it drops into the same tray.

What is equivalent to a Group 78 battery?

The closest BCI sizes that fit the same tray are Group 59. Always confirm the terminal side and CCA before swapping - a reversed-terminal group can leave your cables short.
