just got a new battery today, an optima redtop. they're on at cosco for only $130 which is the main reason i bough it. the battery cables werent quite long enough to reach the terminals so i modded them to be a lil longer and now they are the side type with the screw in. but my main question is what exactly makes them better if they are at all or is it just a gimmic? this battery puts out 910 cranking amps and 750 cold cranking amps which is significantly more than the factory battery.
