voltages were under load, so they don't equate to completely discharged cells--when a battery
is completely discharged the voltage falls rapidly. The boat is new, so corrosion
is probably not an issue, but I agree with the suggestion to check the voltage drop and wiring
size from the chargers.
For future upgrades, LED replacement bulb for the anchor
light will drop its consumption
to 0.2 amps, a netbook computer will draw 1 amp.
When I replaced my gel batteries with cheap
wet acid ones in Greece
, the operating voltage fell about 0.5v. Things still worked pretty well for over a year, and I was finally able to find decent batteries duty free in Gibraltar
for less than a king's ransom.
At least you are able to enjoy the new boat--I talked to one cruiser who had to run his main engine
10 hours a day to keep the batteries charged on the passage
, but he still made it.
