BATTERIES
Battery Care
16
CAUTION
• The watering interval must adequately maintain the electrolyte level above the top of the plates.
See Figure 16-8, Page 16-18.
• 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 interval. 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 Service
Schedule on page 10-3.
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 malfunctioning valves to ensure maximum
battery life.
See following CAUTION.
CAUTION
• After checking the electrolyte, fully tighten the battery caps to prevent electrolyte leakage.
2.
After the initial six-week inspection, manually check the electrolyte level at least once per year, particularly after
long-term storage or any other period of vehicle inactivity.
See preceding CAUTION.
BATTERY CARE – VEHICLES WITHOUT 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.
Check the electrolyte level weekly
(Figure 16-8, Page 16-18)
. Add water only
after
charging unless the
electrolyte level is below the top of the plates. In this case, add just enough water to cover the plates, charge,
and then check the level again. Never charge batteries if plates are exposed above electrolyte level. For best
battery life, add only distilled water.
See following CAUTION and NOTE.
CAUTION
• Do not overfill the batteries.
NOTE:
A battery watering gun or bottle is available at many auto parts dealers.
3.
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 the proper torque.
See step 8 of Battery Replacement on page 16-15.
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.
