trickle charging sailboat batteries 4D with solar?
I have been told I cannot charge my large 4D marine batteries with a 10 watt solar charger or any solar charger. My batteries are about 200 AmHr each and are too big and weigh about 150 lbs each to take out my boat over the winter hence my quest to use a solar charger and keep them charged in freezing Montana. Since there are two batteries I thought I would plug the solar charger into the boats DC outlet, switch the batteries to "both" and go to AZ for the winter. Anyone out there have any ideas if all this would work and if not why not and what I could do to make it work without plugging into AC? Thanks! Sailor Pat
