Checking the Electrolyte Level
T3-020_2
Maintenance free batteries used in normal temperate
climate applications should not need topping up. However,
in certain conditions (such as prolonged operation at
tropical temperatures or if the alternator overcharges) the
electrolyte level should be checked as described below.
1 Get access to the battery. See Access Panels.
2 Disconnect and remove battery. See Battery
Disconnection/Connection.
!MWARNING
