universal external laptop battery tester and charger with test charge discharge function
RFNT3 is a multi-function battery testing device, having the features below:
Dimensions: 201 x 99 x 35 mm
Adapter Input: AC 100 ~ 240 V Output: DC 24V 2.65A
Segment LCD with white backlight + LED in red and green
Constant current discharge for double loads, inner load & external load
Constant current and constant voltages are the main mode. Active charge and pre-charge are available according to different battery voltage.
There is a connection between current intensity and charge mode.
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
Inner load: 0 ~ 1000mA, adjustable continuously via Battery Manager
External load: 0mA, 500mA, 1000mA, 1500mA, 2000mA, five gears with dip switches offered
Tester will stop discharging if one of the conditions below is met.
1) Remaining capacity ≤ set value
2) Voltage ≤ set value
3) Current intensity reduce to zeroTest
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 LCDCapacity 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 chip50% Capacity
CD50%: charge firstly, and then discharge to 50% capacity
DC50%: discharge firstly, and then charge to 50% capacityOnline Functions
