BATTERV INSPECTION

---------------------------------
Charging method using a variable-current (voltage) type charger
By turning the charging
voltage
adju~t
dial, set the
charging voltage at 20 - 25 V.
NOTE:
----------
Measure the open-circuit
Voltage should be measured 30 minutes
voltage prior to charging.

AMP meter
Connect a charger and
AM P meter to the battery
and start charging.
Make sure the current is
higher than the standard
charging current written
on the battery.
NOTE: _
Set the charging voltage at 16 - 17
V.
(If
the setting is lower, charging will be
insufficient. If too high, the battery will
be over-charged'>
NO
Adjust the voltage so that
current is at standard
charging level.
Set the timer according to the
charging time suitable for the
open-circuit voltage.
Refer to "Battery condition
checki ng steps."
YES
Monitor the amperage for
3 - 5 minutes to check if the
standard charging current is
reached.
NO
If the current does not
exceed standard charging
current after 5 minutes,
replace the battery.
In case that charging requires more than 5 hours, it is advisable to
check the charging current after a lapse of 5 hours. If there is any
charge in the amperage, readjust the voltage to obtain the standard
charging current.
Measure the battery open-circuit voltage after having left 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.
