Measure the open-circuit
voltage prior to charging.
Connect a charger and
AMP meter to the battery
and start charging.
NOTE:
Voltage should be measured 30 min-
utes after the machine is stopped.
Make sure 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.
This type of battery charger cannot
charge the MF battery. A variable volt-
age charger is recommended.
Measure the battery open-circuit
voltage after having left the battery
unused for more than 30 minutes.
12.8 V or more --- Charging is com-
plete.
12.7 V or less --- Recharging is re-
quired.
Under 12.0 V --- Replace the battery.
NOTE:
Set the charging time at 20 hours (maxi-
mum).
