M11 Series – Service Manual – 013-007   Batteries

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 manufacturer’s specifications.

Use the Fleetguard® refractometer, Part No. 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.

CAUTION  Do not connect battery charging cables to any CELECT™ part. This can damage the CELECT™ parts.

Use battery tester, Part No. 3377193, 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.
