Re: Getting ready to add shore power
Most shorepower chargers are sized to get a battery fully charged in a reasonable time. If the battery is down much a maintainer at about 1 1/2 amps would take days to full charge a battery. Engine charging is quick to about 80 or 85% state of charge but the last 15 or 20% will take 8 or more hours regardless of alternator size. Fully charged batteries have a much longer life than batteries left partially discharged.
A maintainer is good for keeping a fully charged battery at full charge over a long period of time which is all it was designed to do.
