Keep the electrical connections tight and free of corrosion. A coating of no-
oxide anti-corrosive grease on terminals will usually prevent corrosion. Dry
sand should be kept in trays on which batteries are placed.

sand should be kept in trays on which batteries are placed.
Adjust the charge rate to keep batteries fully charged. Open-cell voltage
should be maintained at the manufacturer's recommended level. Open
circuit voltage on a 12-volt battery should be approximately 12.9 to 13.2
volts d.c., based on the manufacturer's data. Care should be taken not to
overcharge the battery in order to avoid the excessive use of water. Use only
distilled water

When replacing starting batteries, use batteries of equal or greater capacity
than originally installed. The battery should be of sufficient capacity to hold
starting voltage after 30 seconds cranking (10.5 volts d.c. or higher on 12-

If the difference in specific gravity between the highest and lowest cell is
0.050 (50 points) or more, the battery is nearing the end of its useful life
