BATTERY INSPECTION
NOTE: ________________________ _
Since the M F 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 .
CAUTION:
CHARGING METHOD
• 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.
• 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.
• 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.
(Distilled water cannot be added)
• 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 per-
formance will result. Should any electrolyte,
whose specific gravity is 1 .32 or more, be
used , the battery plates will corrode and
battery life will shorten .
