73firebird is absolutely correct on this one! Do not buy one of these worthless Optima batteries. I bought a "red top" one less than 2 years ago for my Prowler and it's gone stone dead twice after less than a month of non-usage. If you store your car or drive it only "now and then", these frickin' batteries are crap. They puke and then won't take a charge. Optima
will not exchange them without you actually sending them the battery. Then they will decide if they will replace it or not. So, what exactly are you supposed to do with your car in the mean-time? (I've got a good suggestion...buy a $40 walmart battery, throw the $140 Optima in the trash and consider it a lesson learned). Never again!
