• When charging the battery, be sure to
remove it from the motorcycle. (If charg-
ing has to be done with the battery
mounted on the motorcycle, be sure to
disconnect the wire at the negative termi-
nal.)
• Never remove the sealing caps of an MF
battery.
• Make 'sure that the charging clips are in
full contact with the terminal and that
they are not shorted together. (A cor-
roded clip on the charger may· cause the
battery to generate heat in the contact
area. A weak clip spring may cause
sparks.)
• Before removing the clips from the bat-
tery terminals; be sure to turn off the
charger's power switch.
• The open-circuit voltage variation for the
MF battery after charging is shown
below. As shown in the figure, the open-
circuit voltage stabilizes about 30 min-
utes after charging has been completed.
Therefore, wait 30 minutes after charging
is completed before measuring the open-
circuit voltage .
