I've been running dual Optima redtops for years, but the truck sitts for long stretches on a tender, and I'm finding these spiral-cell batteries aren't holding up like they used to. So I'm thinking of just replacing with a single really good battery. I've had some advice from friends. some say go cheap like Walmart (as if I'd be seen there!) or Autozone (some say the same batteries as walmart rebadged) and some say go Diehard Platinum from Sears with 48month replacement warranty ($50 more than anyone else)
So what do you guys think? Whats the best breakpoint between Price/Quality/Warranty and ease of replacement if necessary (not going to Johnny's Cheap Battery shop over on South Main St) ?
