OK, looks like I'll probably be trying Napa's top of the line. Convenience and recommendation is why. No Rural King's here, never heard of Dekka. I looked at Costco while getting the usual grocery items today. They carry Interstate at some very reasonable prices, just no lawn and garden batteries. I'm a little surprised no one mentioned a battery from one of the chain discount auto stores----a lack of recommendation probably speaks to the lack of quality? Thanks for the input guys!
