*Charging mode
Constant current + constant voltage. Active charge and pre-charge are available according to different battery voltage.
*Charging current
There is a connection between current intensity and charge mode. The details as below:
Nominal capacity Pre-charge current Fast charge current End charge current
≥6000 400 mA 2500 mA 300 mA
≥3500 400 mA 2000 mA 200 mA
else 200 mA 1000 mA 100 mA

*Standby power consumption
≤1W
*Working temperature
0~40°C 20%-90% RH (Non condensation)
*Storage temperature
-20°C~65°C 10%-95% RH (Non condensation)
*Maximum charging time
Time limit for charging: 8.8h
Time limit for discharging: 8.8h
Time limit for testing: 20s + 10s = chg + disc
Time limit for capacity correction: 8.8h + 20s + 8.8h = disc + pause + chg
Auto quit time for function menu: 10s

Function:
*Charge: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.
*Discharge:Constant current discharge for double loads.
*Test:Testing time is 30 seconds and the purpose is to check both the charging and discharging performances.
*Capacity Correction: 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.
*50% Capacity:
CD50%: charge firstly, and then discharge to 50% capacity
DC50%: discharge firstly, and then charge to 50% capacity
*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.
*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.

Features:

*With one channel, supporting one intelligent battery
*Supporting charge, discharge, test, capacity correction, charge / discharge 50% capacity
*LCD for displaying battery informaiton
*LED for indicating working status
*With charge-key, discharge-key, backlight-key and function-key
*Pre-charge, fast charge and constant voltage charge for charging stages and the variation range of the values of the

constant current and the constant voltage is less than 1%
*Constant current for discharging
*With a USB port for connecting with computers, master machine can monitoring and control slave machine
