CHECKING AND CHARGING THE BATTERY
Charging method using a constant voltage charger
Measure the open-circuit
voltage prior to charging.
Connect a charger and
AMP meter to the battery
and start charging.
NO
YES
Make sure that the current
is higher than the standard
charging current written on
the battery.
Charge the battery until the battery’s
charging voltage is 15 V.
Measure the battery open-circuit volt-
age after leaving the battery unused for
more than 30 minutes.
12.8 V or more --- Charging is complete.
12.7 V or less --- Recharging is required.
Under 12.0 V --- Replace the battery.
This type of battery charger cannot
charge the MF battery. A variable
voltage charger is recommended.
Voltage should be measured 30
minutes after the machine is
stopped.
NOTE:
Set the charging time at 20 hours
(maximum).
