CHECKING THE BATTERY

NOTE:

Since the MF battery is a sealed-type battery, it is not possible to measure the specific gravity of the electrolyte in order to check the charge state of the battery. Therefore, the charge of the battery has to be checked by measuring the voltage at the battery terminals.

CAUTION:

CHARGING METHOD

This is a sealed-type battery. Never remove the sealing caps. If the sealing caps have been removed, the balance will not be maintained and battery performance will deteriorate.

Charging time, charging current and charging voltage for the MF battery are different from those of general type batteries. The MF battery should be charged as explained in “CHARGING METHOD”. If the battery is overcharged,

the electrolyte level will drop considerably. Therefore, take special care when charging the battery.

WARNING

Battery electrolyte is dangerous; it contains sulfuric acid which is poisonous and highly caustic.

Always follow these preventive measures:

Avoid bodily contact with electrolyte as it can cause severe burns or permanent eye injury.

Wear protective eye gear when handling

or working near batteries. Antidote (EXTERNAL):

SKIN - Wash with water.

EYES - Flush with water for 15 minutes and get immediate medical attention.

Antidote (INTERNAL):

Drink large quantities of water or milk followed with milk of magnesia, beaten egg or vegetable oil. Get immediate medical attention.
