Batteries generate explosive hydrogen gas and
contain electrolyte which is made of poison-
ous and highly caustic sulfuric acid.
Therefore, always follow these preventive
measures:
• Wear protective eye gear when handling or
working near batteries.
• Charge batteries in a well-ventilated area.
• Keep batteries away from fire, sparks or open
flames (e.g., welding equipment, lighted
cigarettes).
• DO NOT SMOKE when charging or han-dling
batteries.
• KEEP BATTERIES AND ELECTROLYTE OUT
OF REACH OF CHILDREN.
• Avoid bodily contact with electrolyte as it
can cause severe burns or permanent eye
injury.
FIRST AID IN CASE OF BODILY CONTACT:
EXTERNAL
• Skin ~ Wash with water.
• Eyes -- Flush with water for 15 minutes and
get immediate medical attention.
INTERNAL
• Drink large quantities of water or milk fol
lowed with milk of magnesia, beaten egg or
vegetable oil. Get immediate medical atten-
tion.
3. Check:
• Battery condition
Battery condition checking steps:
• Connect a digital volt meter to the batteryter-
minals.

NOTE:
The state of a discharged MF battery can be
checked by measuring open circuit voltage (the
voltage measured with the positive terminals
being disconnected).
