Buying a Group 34R battery

Match the group size (Group 34R) and aim for at least 550 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 34R 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 34R battery need?

Group 34R vehicles in our data ship with 540-710 CCA (typically around 550). Match your car's original rating or go higher - aim for the top of that range in cold climates.

Is a Group 34R battery AGM or flooded?

Group 34R 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 34R battery?

A BCI Group 34R case measures 260×173×205 mm (L×W×H). Any Group 34R battery uses that footprint, so it drops into the same tray.

What is equivalent to a Group 34R battery?

The closest BCI sizes that fit the same tray are Group 34, Group 124R. Always confirm the terminal side and CCA before swapping - a reversed-terminal group can leave your cables short.
