BATTERY INSPECTION
NOTE:
Since the MF battery is of a sealed-type con-
struction, it is impossible to measure the spe-
cific gravity of the electrolyte in order to check
the state of charge in the battery. Therefore, to
check the state of charge in the battery, volt-
age must be measured at the battery terminals.

CHARGING METHOD
8 This battery is sealed type. Never remove
sealing caps even when charging. With the
sealing cap removed, this balancing will not
be maintained, and battery performance will
lower gradually.
8 Never add water. If distilled water is added,
chemical reaction in the battery will not pro-
ceed in the normal way, thus making it im-
possible for the battery to operate regularly.
8 The charging time, charging current and
charging voltage for the MF battery is differ-
ent than general type batteries.
The MF battery should be charged as in-
structed in the “Charging method”. Should
the battery be overcharged, the electrolyte
level will lower extremely. Therefore, use
special care when charging the battery.
8 Avoid using any electrolyte other than speci-
fied. The specific gravity of the MF battery
electrolyte is 1.32 at 20°C (68°F). (The spe-
cific gravity of the general type battery elec-
trolyte is 1.28. ) If the electrolyte whose spe-
cific gravity is less than 1.32, the sulfuric acid
will decrease and thus low battery perfor-
mance will result.
Should any electrolyte, whose specific grav-
ity is 1.32 or more, be used, the battery plates
will corrode and battery life will shorten.
1. Remove:
8 Battery box cover
Refer to “COVER AND PANEL” section.
2. Remove:
8 Battery
NOTE:
Remove the (–) lead first.
