BATTERY INSPECTION

INSP

ADJ

Measure the open-circuit
voltage prior to charging.

Connect a charged and
AMP meter to the battery
and start charging.

Make sure that the current
is higher than the standard
charging current written on
the battery.

By turning the charging
voltage adjust dial, set the
charging voltage at 20

X

24 V.

Adjust the voltage so that the
current is at the standard
charging level.

Monitor the amperage for
3

X

5 minutes to check if the

standard charging current is
reached.

Set the time according to the
charging time suitable for the
open-circuit voltage.
Refer to “Battery condition
checking steps”.

If the current does not
exceed the standard
charging current after 5
minutes, replace the battery.

If charging requires more than 5 hours, it is advisable to check the charging current
after a lapse of 5 hours. If there is any change in the amperage, readjust the
voltage to obtain the standard charging current.

Measure the battery open-circuit voltage 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.

YES

NO

YES

NO

NOTE:

Voltage should be measured 30
minutes after the machine is stopped.

NOTE:

Set the charging voltage at 16

X

17 V.

(If the setting is lower, charging will be
insufficient. If too high, the battery will
be over-charged.)

Charging method using a variable voltage charger
