2. Neutralize the acid in the electrolyte by pouring baking soda on the
spill.
3. Remove the neutralized electrolyte using a disposable rag or paper
towel.
While the batteries are relatively maintenance-free, there are a few
things you can do to increase their effectiveness and life:
• Keep your batteries fully charged. Batteries that are kept fully or
near fully charged last longer than batteries stored with a partial
charge. The charge level of the batteries can be monitored using the
voltmeters on the helm instrument panel.
• Inspect the batteries at least once every 30 days.
Disconnect the batteries before cleaning them.
• Periodically clean the battery terminals and cable connections.
Remove any accumulation of dirt on the top of the battery case. Use
a wire brush to clean the terminals. Coating the terminals with a
terminal protecting product will help reduce corrosion that can form
in these areas.
• Check that the battery cables are securely attached to the terminal
posts. Tighten the terminal nuts 1/4 turn beyond finger-tight using a
wrench.
• 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, add DIS-
TILLED water only until the electrolyte is at the correct level. DO
NOT OVERFILL the cells.
• 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 charge is lost. Avoid storing the
batteries in a humid place. Humidity causes the terminals to cor-
rode.
• Check the battery charge level every three months using a hydrom-
eter 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 the batteries.
