Check the battery frequently for signs of
corrosion. If corrosion is evident, clean the
terminal posts with a baking soda and water
solution and a wire brush. Disconnect the battery
terminals before cleaning.
Check the fluid levels in the cells. NOTICE: Some
batteries are sealed and cannot be filled. A level
of approximately 1/4 to 1/2 in. (6 to 13 mm) above
the plates is sufficient. If needed, fill with distilled
water; do not overfill!
WARNING! Lead acid
battery fluid can cause severe burns.
During extended periods of non-use, batteries will
self-discharge and should be recharged. Before
recharging, disconnect the battery terminals and
remove the battery from your boat. Recharge the
battery according to the directions enclosed with
your battery and battery charger. When installing
the battery in your boat, make sure the battery is
secured in the battery box, the terminals are tight
and all protective covers are in place.
WARNING!
Hydrogen gases produced by a lead acid
battery while it is charging, or the engine is
running, can cause an explosion and/or a fire.
