Adapter   Input: AC 100 ~ 240 V   Output: DC 19V 4.74A
Display mode
Segment LCD with white backlight + LED in red and green
Charging mode
Constant current + constant voltage
Charging current
Maximum charging current of each channel: 2.5A
Standby power consumption≤1W
Working temperature
0~40℃        20%-90% RH (Non condensation)
Storage temperature
-20℃~65℃    10%-95% RH (Non condensation)
Maximum charging time: 8 hours
Two channels can work independently and serve two intelligent batteries separately. Active, pre-charge, constant current and constant voltage are the stages of charging mode. The initial charging mode depends on the battery voltage, so active and pre-charge don't happen to every batteries.
Testing time is 30seconds and the purpose is to check both the charging and discharging performances. After finishing test, LED flickers with green color and LCD reports the test result.
Normal:              Test           OK            Shown on LCD
Abnormal:            Test           NG            Shown on LCD
Possible causes and solutions for the abnormal:
1)Cause: battery voltage is too low to discharge
   Solution: try to charge the battery to raise voltage
2)Cause: remaining capacity is too full to charge any more
   Solution: try to discharge the battery to reduce the remaining capacity
3)Bad contact of battery connecting wires
4)Damaged battery
5)Tester trouble
Tester can be connected with master machine via a USB port. Users can monitor, control and set parameters via Battery Manager software in the master machine.
Battery information can be monitored via three windows.
1.Home screen
Battery bar and brief information can be read on home screen.
2.Battery detail information window
Show smart battery data in real time and the data can be saved and printed in image format.
3.Battery graph window
Voltage, current and capacity are traced in curves.
Battery Manager can control slave machine completely. Right-click menu on the battery bar includes the related commands.
Users can set working parameters via set parameter window in Battery Manager.
1.Active cooling
2.Active batteries of zero voltage
When a battery is deep discharged, the discharge protection circuit will start up and the voltage in the battery connector will become zero voltage. In this case, an appropriate voltage should be supplied to active the battery.
3.Battery identification
Battery information can be read from battery management chip after establishing communication.
4.Intelligent protection
Against over-current, over-voltage, over-charge, over-heat and short circuit.
5.Suitable for almost all laptop batteries, above 95%
