IMPURITY
ALLOWABLE CONTENT (PARTS
PER MILLION)
EFFECTS OF IMPURITY
Copper 5.0
Increased self-discharge, lower
on-charge voltage
Iron 3.0
Increased self-discharge, lower
on-charge voltage
Magnesium 40.0 Reduced life
Nickel None allowed Intense lowering of on-charge voltage
Nitrates 10.0 Increased sulfation of negative plate
Nitrites 5.0 Plate corrosion, loss of capacity, reduced life
Platinum None allowed Violent self-discharge, lower on-charge voltage
Selenium 2.0 Positive plate shedding
Zinc 4.0 Slight self-discharge of negative plates
BATTERY CARE – VEHICLES EQUIPPED WITH THE OPTIONAL 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. For 8-volt batteries, tighten hold-down retaining nuts to
106 lb·in (12 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 1-4. See following WARNING.
WARNING
• If battery wire terminals are damaged or corroded, replace or clean them 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 Interval for
New Vehicles on page 14-8. See Watering Batteries with the SPWS on page 14-10.
CAUTION
• The watering interval must adequately maintain the electrolyte level above the top of the plates.
See Figure 14-3.
• Water the batteries only AFTER charging.
NOTE: Bottled distilled water, with the hand pump is recommended for private consumer SPWS applications.
