The RFNT2 Laptop Battery Tester is a versatile device designed for testing and charging intelligent laptop batteries. It features two independent channels, allowing it to support and process two batteries simultaneously.

Function Description

The primary functions of the RFNT2 include:

Charging: The device supports active, pre-charge, constant current, and constant voltage charging stages. The initial charging mode adapts based on the battery's voltage.
Testing: A 30-second test checks both the charging and discharging performances of the battery. After the test, the LED flickers green, and the LCD displays the test result (Test OK or Test NG).
Monitoring: Battery information can be monitored in real-time through three windows:
- Home screen: Displays battery bar and brief information.
- Battery detail information window: Shows smart battery data in real-time, with options to save and print data in image format.
- Battery graph window: Traces voltage, current, and capacity in curves.
Online Functions: The tester can be connected to a computer via a USB port, allowing users to monitor, control, and set parameters using the "Battery Manager" software. This software enables complete control over the slave machine, with right-click menu options on the battery bar for various commands. Users can also set working parameters through the "set parameter" window in Battery Manager.
Active Cooling: The device incorporates active cooling to maintain optimal operating temperatures.
Active Batteries of Zero Voltage: For deeply discharged batteries where the discharge protection circuit has activated, the device can supply an appropriate voltage to reactivate them.
Battery Identification: It can read battery information from the battery management chip after establishing communication.
Intelligent Protection: The RFNT2 is equipped with protection mechanisms against over-current, over-voltage, over-charge, over-heat, and short circuits.
Wide Compatibility: It is suitable for almost all laptop batteries, covering over 95% of models.

Usage Features

Power Up: Connect the adapter to an AC power source and then connect the tester. The LCD will display battery information, and LEDs will light up momentarily if a battery is connected. If no battery is connected, both the LCD backlight and LEDs will light up momentarily.
Connecting Battery: Ensure the connecting wire fits the battery, is plugged into the battery socket correctly, and that there are no poor connections.
Normal Charge: Press the charge button to initiate charging. Battery information will be displayed on the LCD in real-time.
Active Charge: If a battery needs activation (i.e., the tester cannot display battery information), press the charge button to start active charge. The tester will proceed to normal charge after successful activation. The time limit for active charge is 60 seconds.
Test Function: Press the test button to begin testing the battery. Charging/discharging current and test results will be shown on the LCD screen.
Online Operation: Connect the tester to a computer via a USB cord, launch the "Battery Manager" software, and refer to the "Battery Manager User Manual" for detailed instructions. Ensure the "Battery Manager" software and USB drive program are installed on the computer.

Maintenance Features

Troubleshooting Test Abnormalities:
- Cause 1: Battery voltage too low to discharge.
  - Solution: Try to charge the battery to raise its voltage.
- Cause 2: Remaining capacity too full to charge any more.
  - Solution: Try to discharge the battery to reduce its remaining capacity.
- Cause 3: Bad contact of battery connecting wires.
  - Solution: Check and ensure secure connections.
- Cause 4: Damaged battery.
  - Solution: The battery may need replacement.
- Cause 5: Tester trouble.
  - Solution: Contact support for assistance.
