I have had some problems with my smart charger
and house battery
bank in the last few years. I have 2 105 ah deep cycle batteries
connected as 12 volt, both the same model. This last year, it seems that when I connect to 240 volts (I am in Australia
, that is normal shore power) one of my house batteries
dries out. The other never does, even though they are connected. After topping up with distilled water
, the hydrometer tells me the battery
is OK, its in the green.
Some other things have happened this year : often, when I turn off the motor
, the open circuit alarm
does not activate as it should until I turn off the key. Also, my masthead anchor
light sometimes shines very brightly, and at other times hardly at all, you would think it is not on.
Two years ago, I plugged in to shore power
, the Enerdrive ePower charger
told me the battery poles were reversed, even though my polarity sensor said all was good, in the green. I sent it off to the techs, they said there was nothing wrong but replaced the internals anyway.
I am planning to buy 2 new house batteries, even though one of these is still OK, but thought I would ask the Forum before I spend the bucks.
Any thoughts ?
