BATTERY INSPECTION
NOTE:
The battery is a sealed MF type battery.
Therefore, it is possible to measure the
specific gravity of the electrolyte in a
testing sequence. Then, in order to check
the conditions of the battery, measure the
voltage at the terminals.
CAUTION:
RECHARGING THE BATTERY
• The battery is a sealed type battery.
During the recharging of the battery the
seals should never be removed.
• With the seals removed the electrolyte
chemical proportion will be affected and
the battery performance will decrease
gradually.
• Do not add water. If distilled water is
added, the chemical reaction in the
battery will divert from the ideal,
impairing the efficiency.
• The MF battery charging time, current
and voltage are different from those of
a conventional battery. The MF battery
should be charged as described in
"Charging the Battery." If the electrolyte
level is too low, the battery may be
overcharged. Therefore, take special care
when charging the battery.
• The use of any electrolyte other than
that specified is forbidden. The MF
battery electrolyte specific gravity is 1.32
at 20°C (68°F). (The conventional
battery electrolyte specific gravity is
1.28.) If the electrolyte specific gravity
is less than 1.32, the hydrogen sulfate
will lose power, resulting in low battery
performance, plate corrosion and reduced
service life.
