Battery care
WARNING
EWM00330
Battery electrolytic fluid is dangerous; it
contains sulfuric acid and therefore is poi-
sonous and highly caustic.
Always follow these preventive measures:
●
Avoid bodily contact with electrolytic
fluid as it can cause severe burns or per-
manent eye injury.
●
Wear protective eye gear when handling
or working near batteries.
Antidote (EXTERNAL):
●
SKIN - Flush with water.
●
EYES - Flush with water for 15 minutes
and get immediate medical attention.
Antidote (INTERNAL):
●
Drink large quantities of water or milk
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 fol-
low these preventive measures:
●
Charge batteries in a well-ventilated ar-
ea.
●
Keep batteries away from fire, sparks, or
open flames (for example: welding
equipment, lighted cigarettes, and so
on.)
●
DO NOT SMOKE when charging or han-
dling batteries.
KEEP BATTERIES AND ELECTROLYTIC
FLUID OUT OF REACH OF CHILDREN.
Batteries vary among manufacturers. There-
fore the following procedures may not always
apply. Consult your battery manufacturer’s in-
structions.
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.
