I've been through this one before:

Optima does not make a direct replacement battery for the PT. In addition, the PT requires a reversed-post or "R" model number. Simply spinning the battery 180 won't do it because the goofy cables won't reach, and *** more importantly *** one of the terminals is just way too close to the metal fender [:0]
Use my research or do your own, but be aware that the traditional notion of a simple battery r/r has become more involved.
