Protable laptop battery tester with Charge and Discharge function can be connected to computer

1. Tester, charger and discharger 2. fit for most of laptop batteries 2. LED for indicating working status

RFNT3 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% capacityDC50%: 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 information*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
