This question is about like asking what kind of oil to use, or what filter is best, or what tires should I buy. I ran 2 red top Optima dual post batteries for over 14 years. They were made in '04 and only died last year, I think because my boy took them out of the suburban and left them sitting on the ground for several months. I am a fan of Interstate. I have been using them in most vehicles I run, mostly because the local tractor store carries them. I like them just fine, running 2 in my Suburban now. I have had interstate batteries that last 10+ years. To each his own. I have had bad luck with walmart batteries and since the closest walmart is 250 miles away, I won't buy one from them.
