Testing terminal (-) => Battery terminal
(-)
NOTE:
The conditions of a discharged MF battery
can be checked through the measurement
of the voltage in the open circuit (voltage
measured with the positive terminal
disconnected).
Open circuit voltage
12.8 V or more
• Check the battery conditions according to
the instructions in the figures.
Example:
Open circuit voltage = 12.0 V
Charging time = 6.5 hours
Charge conditions of the battery = 20 ~
30%
************************************
5. Charging method for the MF battery:
CAUTION:
• If the standard current charge cannot be
stabilized, make sure not to exceed it.
• Remove the battery from the motorcycle
before charging it. (If, for any reason, it
