I have a Rolls 325 ah
battery with a cell I can't get SG above 1.1 with
charging and then
equalization (with
solar panels at 16+v at 5+amps). I've emailed Rolls over a week ago and a local
marine store (on
Vancouver Island) has called (message machine) to check on replacing a
single cell (that is one of their sales pitches). No answers anywhere.
email or
phone. Rolls has a
service ticket system on their site and it even tracks and tells me how many days it has been since submitting a question. I can imagine being somewhere
remote and having this kind of
service. Right now I'm thinking golf cart
battery systems are a lot more sensible for voyaging. Available everywhere and less expensive. Dependency on fiddly systems isn't very resilient.
