BATTERY CARE – VEHICLES EQUIPPED WITH THE SINGLE-POINT WATERING SYSTEM
(SPWS)
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; use 1 cup (237 mL) baking soda per 1 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.
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 retaining nuts on the two inner hold-downs to
110 in·lb (12.4 N·m), and tighten the retaining nuts on the two outer hold-downs to 55 in·lb (6.2 N·m). The
terminal connections should be clean and tight, and any worn insulation or frayed wires should be replaced.
Tighten battery terminals to proper torque.
See Connecting the Batteries – Electric Vehicles on page 13.
