Function Introduction
Charge
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.
Test
Testing time is 30 seconds and the purpose is to check both the charging and discharging performances.
After finishing test, LED flickers with green colour 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

Online Functions
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.
Monitoring
Battery information can be monitored via three windows.
◇Home screen
Battery bar and breif information can be read on home screen.
◇Battery detail information window
Show smart battery data in real time and the data can be saved and printed in image format.
◇Battery graph window
Voltage, current and capacity are traced in curves.
Control
Battery Manager can control slave machine completely. Right-click menu on the battery bar includes the
related commands.
Parameters
Users can set working parameters via set parameter window in Battery Manager.
Others
◇Active cooling
◇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.
◇Battery identification
Battery information can be read from battery management chip after establishing communication.
◇Intelligent protection
Against over-current, over-voltage, over-charge, over-heat and short circuit.
◇Suitable for almost all laptop batteries, above 95%

Operation
Power Up
1) Connect the adapter to AC power source
2) Connect the tester with the adapter
LCD shows battery information and LED lights up for a moment if a battery has been connected to the
tester.
Both LCD backlight and LED lights up for a moment if no battery has been connected to the tester.
Connecting Battery
◇Make sure the connecting wire fits the battery
◇Make sure the connecting wire is plugged into the battery socket in correct direction
◇Make sure no poor connections
Charge
◇Normal charge
Tester starts to charge your battery after you press the charge button. Battery information will be showed

on LCD screen in real time.
◇Active charge
If the battery needs to be activated, tester can not show any battery informaiton. In this case, you should
press the charge button to start up active charge. Tester will go into normal charge process after the
battery is activated successfully.
Time limit of active charge: 60 seconds
Test
Tester starts to test your battery after you press the test button. Charging / discharging current and test result
will be showed on LCD screen.
Online Functions
1) Connect tester to your computer via USB cord
2) Startup Battery Manager
3) Refer to Battery Manager User Manual
Remarks: Battery Manager software and USB drive program should be installed in your computer before you
use this function.
