BATTERY CARE
–
VEHICLES EQUIPPED WITH THE SINGLE-POINT WATERING
SYSTEM
To keep batteries in good working condition, follow this maintenance program on a regular basis:
1. Keep the batteries clean and free of corrosion. Wash tops and terminals of batteries with a solution of
baking soda and water (1 cup (237 mL) baking soda per gallon (3.8 L) of water). Rinse solution off of the
batteries. Do not allow this solution to enter the battery. Be sure terminals are tight. Let the terminals dry
and then coat with Battery Terminal Protector Spray (CCI P/N 1014305).
See following NOTE.
NOTE: Dispose of waste water properly.
2. The battery hold-downs should be tight enough so that the batteries do not move while the vehicle is in
motion, but not so tight as to crack or buckle the battery case. Tighten hold-down retaining nuts to 40 in-
lb (4.5 N·m). The terminal connections should be clean and tight, and any worn insulation or frayed wires
should be replaced. Tighten battery terminals to 110 in-lb (12.4 N·m).
See following WARNING.

WARNING
• If battery wire terminals are damaged or corroded, they should be replaced or cleaned as
necessary. Failure to do so may cause them to overheat during operation and could result in
fire, property damage, or personal injury.
3. After use, charge the batteries. The batteries should never be left discharged any longer than absolutely
necessary (do not leave discharged overnight).
4. Water the batteries monthly or according to the watering interval.
See Establishing the Watering Inter-
val for New Vehicles on page 37.
See Watering Batteries with the SPWS on page 42.
CAUT ION
• The watering interval must adequately maintain the electrolyte level above the top of the
plates. See Figure 26.
• Water the batteries only AFTER charging.
Establishing the Watering Interval for New Vehicles
If you do not already have a battery watering interval for your vehicles, manually check the battery water level
weekly to establish the correct watering interval. Thereafter, water batteries according to the established inter-
val. During periods of heavy use, add additional watering as required.
Single-Point Watering System Maintenance
1. For vehicles newly equipped with the Single-Point Watering System, the initial electrolyte level check on
all battery cells verifies that all the valves in the SPWS are functioning correctly.
See the Periodic Ser-
vice Schedule on page 32
. If a valve is fails to open, the cell will eventually dry out. The initial one-time
inspection of all cells will identify any occurrence of a valve that fails to open. If a valve fails to close, it
will become evident due to the cell overflowing during routine watering. Either failure scenario is rare, but
should be monitored in the initial inspection and during routine watering sessions. Replace malfunction-
ing valves to ensure maximum battery life.
See following CAUTION.
CAUT ION
• After checking the electolyte, fully tighten the battery caps to prevent electolyte leakage.
2. After the initial six-week inspection, manually check the electrolyte level at least once per year, particu-
larly after long-term storage or any other period of vehicle inactivity.
See preceding CAUTION.
