So I got to the boat earlier and looked at the panel meter. It was reading about 11.5V (maybe). I popped downstairs with my multimeter and measured a little over 11V on one of the banks, a little under on the other. Obviously, not good. So what's this telling me? I have the ProTech 1240iPLUS charger in there (is that the original one?). According to the 1240iPLUS manual, for flooded batteries the charger will either be in absorption mode (outputting 14.7V) or float/sustaining mode (outputting 13.5V). Shouldn't the reading at the batteries be somewhere in the range of 13.5 to 14.7? If this were a car, reading 11V on the batteries would mean the batteries are shot. But since it's a boat and the batteries are hooked to a charger, doesn't this also indicate that the charger isn't functioning properly?
Am I wrong? Missing something?
