If conventional batteries are used, remove the cell caps or covers, and check the electrolyte level.
NOTE: Maintenance-free batteries are sealed and do not require the addition of water.
Fill each battery cell with distilled water. Refer to the battery manufacturer’s specifications.
Use the Fleetguardยฎ refractometer, Part Number CC-2800, to check the specific gravity of the battery electrolyte.
Refer to the battery fluid column in the refractometer to determine the state of charge of each battery cell.
If water has been added to a dry cell, recharge the battery to mix the added water with the existing battery electrolyte, to prevent incorrect readings .
Use a carbon-pile load (battery/alternator tester) to test the output amperage of maintenance-free or conventional
vent cap batteries.
If the output amperage is low, use a battery charger to charge the battery. Refer to the manufacturer’s
instructions.
Replace the battery if it will not charge to the manufacturer’s specifications or will not maintain a charge.
