CHECKING THE BATTERY
●
Check the condition of the battery using the
following charts.
Example:
●
Open-circuit voltage = 12.0 V
●
Charging time = 6.5 hours
●
Charge condition of the battery = 20 ~ 30%
●
Charging method for MF batteries
CAUTION:
●
If it is impossible to set the standard
charging current, be careful not to
overcharge.
●
When charging the battery, be sure to
remove it from the motorcycle. (If
charging has to be done with the battery
mounted on the motorcycle, be sure to
disconnect the wire at the negative
terminal.)
●
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 corroded 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
battery 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
minutes after charging has been
completed. Therefore, wait 30 minutes
after charging is completed before
measuring the open-circuit voltage.
