does any one have a sterling "smart" charger
for the batteries in his boat??
if so do you keep hearing a humming noise
while plugged to shore power
more over does this humming continues (around 50mn
)long after you have unplugged the shore line ?? it is really annoying and quite loud !
the batteries I have are lead acid sealed maintenance
free 75 amps/h and and they always topped of ( 14.5 to 15+ volts ) which is excessive !! but the smart charger
is supposed to regulate the voltage shouldn't it ? well If any one can help me with this issue please advise.
