6. Operating Instructions
6.1. Charging Batteries
- Insert Batteries: Place one or more compatible batteries into the charging slots, ensuring correct polarity. The charger will automatically detect the battery type (Li-ion or Ni-MH) and display its voltage.
- Select Mode: Press the MODE button to cycle through available modes: CHARGE, FAST TEST, and NOR TEST. For standard charging, select CHARGE.
- Select Current: While in CHARGE mode, press the CURRENT button to select the desired charging current (300mA, 500mA, 700mA, or 1000mA). The selected current will apply to all inserted batteries.
- Start Charging: The charger will automatically begin charging after a few seconds of inactivity or after selecting the current. The LCD will display real-time charging status.
- Completion: When charging is complete, the LCD will display "End".
6.2. Battery Testing Modes
The Lii-500 offers two testing modes to determine battery capacity:
- FAST TEST: This mode quickly determines the battery's capacity by first discharging and then fully charging the battery.
- NOR TEST (Normal Test): This mode provides a more accurate capacity measurement. It involves fully charging the battery, then discharging it to measure capacity, and finally recharging it.
To use a test mode:
- Insert batteries.
- Press the MODE button to select either FAST TEST or NOR TEST.
- Press the CURRENT button to select the desired discharge/charge current for the test.
- The test will begin automatically. The LCD will show the measured capacity (mAh) upon completion.
6.3. USB Output Function
The charger can function as a power bank to charge 5V electronic devices via its USB output port. This function is only available when 3.7V Li-ion batteries are inserted into the charging slots.
- Insert charged 3.7V Li-ion batteries into the slots.
- Connect your 5V electronic device (e.g., smartphone) to the USB output port using a compatible USB cable.
- The charger will provide 5V 1000mA output.
7. Battery Compatibility
The Lixada Lii-500 is compatible with a wide range of cylindrical rechargeable batteries. Ensure your batteries fall within the specified dimensions and voltage types.
- Li-ion Batteries (3.7V): 26650, 22650, 18650, 18490, 18500, 17500, 17355, 16340 (RCR123), 14500, 10440.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not powering on | No power, faulty adapter, loose connection. | Check power outlet, ensure adapter is securely connected, try a different outlet. |
| Battery not charging / "null" displayed | Incorrect battery insertion, incompatible battery, deeply discharged battery, faulty battery. | Re-insert battery with correct polarity, ensure battery type/size is compatible, try a different battery. Some deeply discharged batteries may not be recognized immediately. |
| USB output not working | No Li-ion 3.7V battery inserted, battery too low, faulty USB cable/device. | Ensure charged 3.7V Li-ion batteries are in slots, check battery charge level, try a different USB cable or device. |
| Charger overheating | Poor ventilation, high ambient temperature, faulty battery. | Ensure adequate ventilation around the charger, operate in a cool environment, remove any faulty batteries. |
