
When the display indicates “Charge completion” and the indicator light is on, the battery finishes
charge. The charger enters floating charge, with current of 1-3 amperes. Please check electrolyte
height in the battery frequently and fill distilled water timely as required.

Disconnect the power switch, and disconnect the output cable plug of the charger and plug of
battery and the charge is completed.
EQUALIZING CHARGE
When the battery group has been used for some time, the performance parameters of the batteries may
vary differently, so equilibrium (constant current) charge is required.
If equalizing charge is required, press the key for “Balance” charge, turn on the power switch, then the
indicator light for “Balance” is on. The charger enters into equalizing charge status, the current value
reduces from the rated value to a constant current value during charge, meanwhile, the display indicates
“-FC-“. When the equalizing charge is completed, manual turning off is required (note: the output current
of the charger under equalizing charge is constant without stop, manual turning off is necessary). Press
the key for “Balance” charge after turning off the charger to make it return to normal charge.
The equalizing charge is a manual operation. Appointed personnel are required to
observe and check voltage and specific gravity of the batteries and determine charge time, manual
power off and charge stop as required.
TROUBLESHOOTING
Failures Causes Troubleshooting
The indicator light for power is
on, the indicator light for failure
is on, the blower is on, the
charger can not start and
charge and the monitor is not
display .
The battery is not connected, or
the output plug of the charger is
inserted into the controller plug of
the electric vehicle.
Connection of the battery should
be corrected.
The indicator light for power is
on, the indicator light for failure
is on, the blower is on, the
charger can not start and
charge and the monitor is not
display .
①
Although the charger and
battery is connected, however,
some part of which is
disconnected.
②
The battery is aging, becomes
invalid and low voltage.
③
The battery is connected
oppositely.
①
Check each connection bolt
and wiring.
②
Check total voltage of
battery and each single voltage
of the battery. In case of open
circuit, aging, invalid, low
voltage of the battery, please
change a new one.
③
Correct the incorrect
connection.
The indicator light for power is
on, the indicator light for failure
is on, the blower is on, the
charger can not start and
charge and the display.
Failure of DC output fuser. Open the side door to check the
fuser. If the fuser is broken,
please change a new one.
Instable charge current, more Long-term heating, poor contact Check the copper plates, if it is
