Re: Battery life short? What to check?
I have 4-6v deep cycle gels that I use for house and starting. They are 13+ years old, and still appear strong. Sitting in the boat all winter, without being plugged in,they lose about 0.05v. I think charging at the proper volage has a lot to do with their longevity. I don't know how much longer the'll last. but so far Isee no end.
