Miscellaneous Maintenance
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, observe
the following precautions when handling a battery.
! WARNING
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.
! WARNING
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. Hy-
drogen 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 corro-
sive acid and should be handled with care. If electrolyte is spilled or splashed on any part of the body, im-
mediately flush the exposed area with liberal amounts of water and obtain medical aid as soon as possible.
