POLOSO Brand Laptop Battery Tester Charger Discharger
Model: RFNT3
Testing the charge/ discharge function is good or bad
Charge ,Discharge,Calibrate capacity,50% capacity function
Compatible with over 95% brands laptop batteries by 14kinds different connectors

Funciton:
*Charge
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.
*Discharge
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
*Test
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
*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.
