RFNT3 Universal Laptop Battery Tester Charger Discharger

RFNT3 Universal Laptop Battery Tester Charger Discharger

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.
