WARNING
Battery electrolytic fluid is dangerous; it
contains sulfuric acid and therefore is
poisonous and highly caustic.
Always follow these preventive mea-
sures:
Avoid bodily contact with electrolytic
G
fluid as it can cause severe burns or
permanent eye injury.
Wear protective eye gear when han-
G
dling or working near batteries.
Antidote (EXTERNAL):

G
and get immediate medical attention.
Antidote (INTERNAL):
Drink large quantities of water or milk
G
followed by milk of magnesia, beaten
egg, or vegetable oil. Get immediate
medical attention.
Batteries also generate explosive hydro-
gen gas; therefore, you should always
follow these preventive measures:
Charge batteries in a well-ventilated ar-
G
ea.
Keep batteries away from fire, sparks,
G
or open flames (for example: welding
equipment, lighted cigarettes, and so
on.)
DO NOT SMOKE when charging or han-
G
dling batteries.
KEEP BATTERIES AND ELECTROLYTIC
FLUID OUT OF REACH OF CHILDREN.
Follow the manual of the battery for the han-
dling of the battery. Batteries vary among
manufacturers. Therefore the following pro-
cedures may not always apply. Consult your
battery manufacturer's instructions.
Procedure
1. Disconnect and remove the battery from
the boat. Always disconnect the black
negative cable first to prevent the risk of
shorting.
2. Clean the battery casing and terminals.
Fill each cell to the upper level with dis-
tilled water.
3. Store the battery on a level surface in a
cool, dry, well-ventilated place out of di-
rect sunlight.
4. Once a month, check the specific gravity
of the electrolyte and recharge as re-
quired to prolong battery life.
