Optima Batteries That Fit Your Vehicle
All REDTOPs (except the 6V) & all YELLOWTOPs (except the H6, 51, DS46B24R, 27 & 31) come with a variety of adapters for fitment. While OPTIMA doesn't offer what we consider to be 'direct-fit' replacements for every vehicle, many owners have successfully used our products in applications that we would consider to be 'custom fitments.' If you are using this battery in a custom fitment, please review the tips found here: Vehicle not in Fitment Guide
