Car Battery Terminal Types and Polarity

A battery can share the right group number yet place the positive post on the wrong side or use the wrong terminal type.

Record the viewing direction

Photograph the installed battery label, cables and post layout before removal. Positive-left and positive-right descriptions require a defined viewing orientation.

Check clearance and connection

Confirm top or side terminals, cable reach, post diameter, hold-down and hood clearance on the exact manufacturer SKU.

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.
