Computer laptop battery power management system for repair tools, laptop repair store - RFNT3

Laptop battery tester

Model NO.: RFNT3

Function: test, charge,discharge,50% cha&disc, intelligent protection

universal external laptop battery tester

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
