How to Find Your Car Battery Group Size

Read the installed battery label and the vehicle manufacturer’s current specification before choosing a replacement group.

Identify the battery position

Some vehicles have separate primary and auxiliary low-voltage batteries. Hybrid and EV traction batteries are different systems.

Compare more than the group

Check voltage, chemistry, CCA, case size, terminal polarity, hold-down, venting and any coding or registration instruction.

Put the answer to work

Start with the actual vehicle label or installed component. Then use our vehicle directory and comparison tools to narrow the research. Any missing condition should be checked with the manufacturer or a qualified installer.
