I have a 2-3 yr old Diehard Deep Cycle Marine Battery. The battery
is stored properly during the winter. In the spring, each cell is
filled to the proper level. This year, the boat launched in late June,
and has been used an average of once a week since.
The other day, the battery was weak. On check, the water level
had fallen to the top of the zinc in two cells. The battery has since
been refilled and is being recharged.
My question: Is this possibly a normal amount of water usage,
in which case I should simply be checking more frequently OR is there
an abnormal condition of the battery causing this, OR is something
external causing this such as excessive charging?
Your help is very much appreciated!
