TESTING THE BATTERY
See Test Procedure 1 – Battery on page 12-10.
PREVENTIVE MAINTENANCE
1.
To keep the battery in good operating condition, remove corrosion immediately. Post connections should be
clean and tight. Frayed or worn wires should be replaced. After all cables have been connected and properly
tightened to 20 ft-lb (27.1 N·m), coat terminals with Battery Terminal Protector Spray (CC P/N 1014305) to
prevent future corrosion.
2.
The battery should be kept clean and dry to prevent self-discharge. Dirt, grime or acid spillage should be
removed. Wash the battery with a bristle brush and a solution of water and bicarbonate of soda (1 cup (237 mL)
baking soda – per 1 gallon (3.8 L) of water). Rinse with water. Do not allow any solution to enter the battery
through the vent cap holes.
See Self-Discharge on page 14-22.
3.
Maintain the proper water level.
See Water Level on page 14-22.
4.
Check the battery periodically to ensure that it is in a full state of charge.
See Charging the Battery on page
5.
Keep the battery hold-down clamp tight.
See Vibration Damage on page 14-22.
SELF-DISCHARGE
Dirt and battery acid can provide a path for a small current draw that slowly discharges the battery. To prevent
self-discharge, the battery should always be kept clean.
Hot weather also has an effect on a battery’s self-discharge rate. The higher the temperature, the quicker a battery will
discharge. Therefore, the battery should be checked more often in hotter climates. When storing the battery, keep it in
a cool place.
See Battery Storage on page 14-24.
WATER LEVEL
The water level should be checked semi-annually to ensure the proper level is maintained. Never allow the water level
to fall below the tops of the plates because this will cause the exposed part of the plate to become permanently inactive.
Check the water level more frequently in hot weather and when the battery becomes old.
VIBRATION DAMAGE
The battery hold-down clamp should always be tight enough to keep the battery from bouncing. Battery life may be
severely shortened if the clamp is too loose. Excessive vibration shortens the life of the battery. It may also cause acid
to leak from the vent caps and corrosion to build up on surrounding metal parts. The acid that is lost reduces the
capacity of the battery and cannot be replaced.
MINERAL CONTENT
For the longest battery life, distilled water should be used in the battery. However, if tap water is going to be used,
contact your local water department to be sure mineral contents are below the levels listed in the following table.
See
following NOTE.
NOTE:
Contact your local water department for mineral content analysis.
