Check the electrolyte specific gravity in each battery
cell.
The lowest limit of the specific gravity for the elec
-
trolyte varies depending on electrolyte temperature.
The specific gravity should be kept within the range
shown below. Charge the battery if the specific grav-
ity is below the limit.
Your machine has two 12-volt batteries with negative (−)
ground.
If one battery in a 24-volt system has failed but the other is still
good, replace the failed battery with one of the same type. For
example, replace a failed maintenance-free battery with a new
maintenance-free battery. Different types of batteries may
have different rates of charge. This difference could overload
one of the batteries and cause it to fail.
