Battery

All lead acid batteries discharge when not in use. Recharge every 30 to 45 days, or when specific gravity drops
below battery manufacturer's specifications.
Refer to specific instructions and warnings accompanying your battery. If this information is not available, ob-
serve the following precautions when handling a battery.
Avoid serious injury from gasoline fire or explosion. Do not use jumper cables and a booster battery
to start engine. Do not recharge a weak battery in the boat. Remove battery and recharge in a ventilated
area away from fuel vapors, sparks or flames.
Batteries contain acid which can cause severe burns - Avoid contact with skin, eyes and clothing.
Batteries also produce hydrogen and oxygen gases when being charged. This explosive gas escapes
fill/vent cell caps and may form an explosive atmosphere around the battery for several hours after it
has been charged. Sparks or flames can ignite the gas and cause an explosion which may shatter the
battery and could cause blindness or other serious injury.
Safety glasses and rubber gloves are recommended when handling batteries or filling with electrolyte.
Hydrogen gases that escape from the battery during charging are explosive. When charging batteries,
be sure battery compartment or area where batteries are located, is well-vented. Battery electrolyte is
a corrosive acid and should be handled with care. If electrolyte is spilled or splashed on any part of
the body, immediately flush the exposed area with liberal amounts of water and obtain medical aid as
soon as possible.
