Do they ALL suck? Everytime I've needed a battery I've bought the AC Delco because I'm a sucker for dealership-what-came-in-the-truck shit. I've bought like 4. Well they've done their jobs I guess to an extent, they start up most days, but damn, leave the (factory) radio on for more than 5 minutes with the truck off and click click click!!! I'm so sick of dealing with these things. Whats your experiece with them? I think next battery for the 86 and 01 will be an Optima, the suburban came with a red top and that bitch performs.
