MAINTENANCE AND ADJUSTMENT OF EV CU800 Service Manual
82
Measure the open-circuit voltage
prior to charging.
Connect a charger and ammeter to
the battery and start charging.
Is the amperage higher than the
standard charging amperage
written on the battery?
Adjust the charging voltage to
20 ~ 25 V
Monitor the amperage for 3 ~ 5
minutes. Is the standard charging
amperage exceeded?
Adjust the voltage to obtain the
standard charging amperage
If the amperage does not
exceed the standard charging
amperage after 5 minutes,
Please contact after-sales
service.
Set the timer to the charging time
determined by the open circuit
voltage.
If the required charging time exceeds 5 hours, it is advisable to check the charging
amperage after 5 hours. If there is any change in the amperage, readjust the voltage to
obtain the standard charging amperage.
Leave the battery unused for more than 30 minutes before measuring its open-circuit
voltage.
12.8 V Charging is complete.
12.0 ~ 12.7 V Recharging is required.
Under 12.0 V → Contact after-sales service.
