3.3.1 Checking and Charging the Battery
WARNING
Batteries generate explosive hydrogen gas
and contain electrolyte which is made of poisonous
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-ventilate2d area.
• Keep batteries away from fire, sparks or open
flames (e.g., welding equipment, lighted
cigarettes).
• DO NOT SMOKE when charging or handling
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 followed
with milk of magnesia, beaten egg or vegetable
oil. Get immediate medical attention.
WARNING
• This is a sealed battery. Never remove the sealing caps because the balance between cells
will not be maintained and battery performance will deteriorate.
• Charging time, charging amperage and charging voltage for an MF battery are different from
those of conventional batteries. The MF battery should be charged as explained in the
charging method illustrations. If the battery is overcharged, the electrolyte level will drop
considerably.
• Therefore, take special care when charging the battery.
