5. Setup

  1. Place the Liitokala LII-600 charger on a stable, flat, and well-ventilated surface.
  2. Connect the supplied power adapter to the DC 12V/5A power interface on the side of the charger.
  3. Plug the power adapter into a suitable electrical outlet. The LCD display will illuminate, indicating the charger is powered on.
  4. Insert the rechargeable battery into one of the four independent slots, ensuring correct polarity (+ and -). The charger will automatically detect the battery type (Li-ion or NiMH) and display its current voltage.

6. Operating Modes

The LII-600 offers two main working modes: AUTO and MANUAL, along with four functional modes: CHARGE, DISCHARGE, TEST, and REPAIR. Each of the four channels operates independently.

6.1. AUTO Mode (Automatic Current Selection)

In AUTO mode, the charger intelligently selects the optimal charging or discharging current based on the battery's internal resistance and type. This is the default mode for convenience.

  1. Insert a battery. The charger will automatically detect it and enter AUTO mode.
  2. The display will show "AUTO" and the automatically selected current.
  3. The charging/discharging process will begin automatically.

6.2. MANUAL Mode (Manual Current Selection)

MANUAL mode allows users to select specific charge or discharge currents. This is useful for specific battery requirements or faster/slower charging.

  1. Insert a battery. Within 8 seconds, press the MODE button to cycle through the functional modes (CHARGE, DISCHARGE, TEST, REPAIR).
  2. While in the desired functional mode, press the CURRENT button to select the desired current. Available charge currents: 250mA / 500mA / 1000mA / 1500mA / 2000mA / 2500mA / 3000mA. Available discharge currents: 250mA / 500mA / 750mA.
  3. After selecting the current, the process will begin. If no button is pressed for 8 seconds, the charger will default to AUTO mode.

6.3. Functional Modes

  • CHARGE Mode: Recharges the battery. The display shows charging progress, voltage, and current.
  • DISCHARGE Mode: Discharges the battery to a safe level. Useful for conditioning NiMH batteries or preparing Li-ion batteries for storage.
  • TEST Mode (Capacity Detection): Measures the actual capacity of the battery.
    1. Insert battery, select TEST mode using the MODE button.
    2. Select desired discharge current using the CURRENT button.
    3. The charger will first fully charge the battery, then discharge it to measure capacity, and finally recharge it. The measured capacity will be displayed.

  • REPAIR Mode (Zero Volt Activation): Attempts to reactivate deeply discharged batteries (zero volt activation). This mode applies a small current to bring the battery voltage to a detectable level, after which normal charging can proceed. Note: Not all deeply discharged batteries can be recovered.
