Checking my batteries for water level this weekend.
Have 2 8D's and 2 sealed 31's. The port 8D had a green growth on both the + and - terminals, plus the tinning was gone off the lugs, now bare copper.

The other 3 batteries were clean as a whistle.

Approx. 6 mos. ago added a 1750 watt invertor (marine)(seprate from my charger) plus new battery cables, closed tinned lugs, heat shrinked and corrosion X on all terminals.

Also have a 30amp. galvanic isolator @ the shore power. I belive my bonding system to be in good shape.

The port batt. had 1 cell that a lot less water, all batts. show 13+ volts.

Any ideas from the faithfull.

Thanks for any ideas,

Jim
