Re: Dual Battery Setup w/ Mean Green Altenator

Yes that is absolutely true, and this is really the only down side to a parallel setup. When you replace the batteries they must be done in pairs, no exceptions. In my case one battery is just not enough in winter to start my truck so even if I had one battery isolated and the other goes dead I am still sol. I have only had one time where one battery went bad suddenly.
