Re: Voltage puzzle
Unfortunately voltage alone doesn't tell you much - a rough indication at best, esp with no load.
With your shore charger you only "put in" 8 amps, and while motoring only 15 to 20 I'd guess.... So how much charge you got to depends on how run down the battery actually was vs its amphours capacity.
