Summary

 

RFNT3 is a multi-function battery testing device, having the features below:

    with one channel, supporting one intelligent batterySupporting charge, discharge, test, capacity correction, charge / discharge 50% capacityLCD for displaying battery informationLED for indicating working statusWith charge-key, discharge-key, backlight-key and function-keyPre-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 dischargingWith a USB port for connecting with computers, master machine can monitoring and control slave machine
Basic Parameters

Adapter    Input: AC 100 ~ 240 V   Output: DC 24V 2.65A

Discharging mode

Constant current discharge for double loads, inner load & external load

Charging mode

Constant current and constant voltages are the main mode. Active charge and pre-charge are available according to different battery voltage.

Active charge:

Tester may not recognize 0V-battery. Users should press the charge key to start up the active charge function. Being activated and going to normal charging status, when the battery establishes communication with the tester.

Charging current

There is a connection between current intensity and charge mode.  

 Function Introduction 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

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 zero

Remarks:

Many batteries can not measure exact current intensity, which cause an else current value appears after you set a value. However, the actual discharging current is the same with your set value.

 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.

Remarks:

Discharging current can be set via Battery Manager. Deep discharge will cause a battery losing communication with tester, so battery dropping phenomenon may happen in the discharging process if the end capacity and voltage are set too low. In such a case, active charge will make the battery work again.

 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.
