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.
