Re: Lifeline Batteries
Few if any cruising sailors don't have a means of maintaining the charge in their batteries. Personally I have solar, wind, a generator and of course, the main engine. Since the state of charge never gets to a critical level, I use all batteries for the house circuit and have no back-up starting battery giving me a total of 880 amp hours of storage.
I have chosen to employ only flooded cell batteries as they can be equalized and thereby renewed regularly.
