Thanks all.
You folks using AGM's..... are you finding that they last at lea st as long as the 5 years my electrolytics do? They cost considerably more so you need them to go at least 7 years, I would think.
Not knowing what brand you use and how you're using them I can't say you would be better off with AGM's. I can say that in my experience using an Interstate battery of good quality gave me 3 years at best and required constant attention to maintenance. Since going to AGM's 6 years ago I have not done anything except inspect them yearly during my normal winter maintenance schedule. I think the high vibration of use on a boat in rough waters that I run in has taken a toll on lead acid batteries. My batteries do take a pounding at times.
