Remove any accumulation of dirt on the top of the
battery case. Use a wire brush to clean the termi-
nals. Coating the terminals with a terminal protect-
ing product will help reduce corrosion that can form
in these areas.
4. Check that the battery cables are securely attached
to the terminal posts. Tighten the terminal wing
nuts 1/4 turn beyond finger tight using a pliers.
5. Check the level of electrolyte in each cell of each
battery. The correct level is just above the plates. If
the fluid level is low, top off the cell with DIS-
TILLED water only. DO NOT OVERFILL.
Remove the batteries from the boat during periods of
extended storage. Store your batteries in a cool (above
freezing temperature), dry area. All batteries lose some
charge during storage, but the lower the temperature
the less loss of charge. Avoid storing the batteries in a
humid place. Humidity causes the terminals to corrode.
Check the battery charge level every 3 months using a
hydrometer or voltmeter. If the specific gravity of the
battery is less than 1.225 or the voltage is less than 12.4
volts, charge the battery. Avoid overcharging.
