Display mode
Segment LCD with white backlight + LED in red and green
Discharging mode
Constant current discharge for double loads, inner load & external load
Charging mode
Constant current and constant voltages are the main mode. Active charge and pre-charge are available according to different battery voltage.
Active charge:
Tester may not recognize 0V-battery. Users should press the charge key to start up the active charge function. Being activated and going to normal charging status, when the battery establishes communication with the tester.
Pre-charge:
Tester goes into pre-charge status when voltage of single cell < 3000mV.
Constant current:
Tester goes into fast charge status when voltage of single cell > 3000mA & < 4200mA. Fast charge current relates to the battery nominal capacity.
At the end of charge:
The current intensity begins to decrease when tester goes into constant voltage charge status. It stops charging when the capacity reaches 100% and the current intensity less than 1A or the current intensity reduce to the end charge current.
Charging current
There is a connection between current intensity and charge mode. The details as below:
The max charge current is 2.5A.
Nominal capacity Pre-charge current Fast charge current End charge current
≥6000 400mA 2500mA 300mA
≥3500 400mA 2000mA 200mA
Else 200mA 1000mA 100mA
Standby power consumption≤1W
Working temperature
0~40℃ 20%－90% RH (Non condensation)
Storage temperature
-20℃~65℃ 10%－95% RH (Non condensation)
Time
Time limit for charging: 8.8h
Time limit for discharging: 8.8h
Time limit for testing: 6s + 6s = chg + disc
Auto quit time for function menu: 10s
Active, pre-charge, constant current and constant voltages 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. For charging mode and current, please refer to the paragraphs of charging mode and charging current on page 2 & 3.
Tester will stop charging if one of the conditions below was met.
1) Remaining capacity ≥ 99% & current intensity = 0
2) Remaining capacity = full charge capacity
3) Current intensity reduce to end charge current when constant voltage charge
4) Remaining capacity reach up the set value
Constant current discharge for double loads
Inner load: 0 ~ 1000mA, adjustable continuously via Battery Manager
External load: 0mA, 500mA, 1000mA, 1500mA, 2000mA, five gears with dip switches offered
Tester will stop discharging if one of the conditions below is met.
1) Remaining capacity ≤set value
2) Voltage ≤set value
3) Current intensity reduce to zero
Remarks:
Many batteries can not measure exact current intensity, which cause an else current value appears after you set a value. However, the actual discharging current is the same with your set value.
Testing time is 12 seconds 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
The battery capacity value in the battery management chip will different from the actual capacity after a battery goes through many recycling cycles. It will affect the use of the battery when the difference reaches a certain degree. Capacity correction is to deep discharge a battery and then fully charge, which will correct the capacity value in the battery management chip.
Remarks:
Discharging current can be set via Battery Manager. Deep discharge will cause a battery losing communication with tester, so battery dropping phenomenon may happen in the discharging process if the end capacity and voltage are set too low. In such a case, active charge will make the battery work again.
CD50%: charge firstly, and then discharge to 50% capacity
DC50%: discharge firstly, and then charge to 50% capacity
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.
All the functions of charge, discharge, capacity correction and 50% capacity are comply with the charging discharging conditions, which are showed on function introduction paragraph inpage 4 & 5, so parameters should be set reasonably. Especially, deep discharge will cause a battery losing communication with tester.
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. Fan
Discharging mode: fan startup
Other modes: fan startup when temperature above 48℃
Fan stop working when temperature below 40℃
6. Trouble alarm
LED flickers in red color and current command stops when one of the conditions below happen.
1). There is not current for around 50 seconds when charge.
2). There is not current for around 25 seconds when discharge.
3). Charging time is above 8.8 hours.
4). Discharging time is above 9.9 hours.
5). Suitable for almost all laptop batteries, above 95%
