I've done a search on batteries and didn't find to many brands mentioned, just battery maintanence. I'm going to replace my deep cycle's this weekend and was wondering what brands you guy's preffered. I have diehards in now and they DIED-HARD, this is their 3rd season. My neighbor works for Excide and he recommended the Stowaway which is a GNB product. I've heard some discussion about the Optima and was looking at their new Troll Fury. What are your words of wisdom? I don't want maintanence talk just brands and how many years they worked.
