Automotive Battery Dimensions

Maximum Outside Dimension Chart for Automotive Batteries

Replacing the battery in most newer passenger vehicles is straight forward. Most people take their vehicle (or battery) to a local automotive store where the staff looks up the year, make and model and then provides a replacement battery that meets the same CA (cranking amps), CCA (cold cranking amps), dimensions and terminal layout as the old battery. Usually the only two deviations from the battery that was in the vehicle are for higher CCA (usually in colder climates) and/or a longer warranty period.

There are times when original battery specifications may not be available for reference, though. Maybe you’re working on an antique or classic, or are converting it from 6v to 12v. Or, maybe you are building a street rod, rock crawler, car hauler, etc and only know what amperage draw you need and what size compartment the battery needs to fit into. We put together the below chart for these scenarios to help you find a battery that will fit your application. All dimensions listed are maximum outside dimensions to the widest point, including terminal posts and flanges (based on data from the BCI Battery Replacement Data Book). Any hold-down flanges at the bottom of a battery are not included in these measurements.

We’ve included as many dimensions as we’ve been able to find, but if you can help fill in any of the gaps please email us at service@raybuck.com.
