BATTERY INSPECTION
●
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 over-
charge.
●
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.
