Lii‑600 4‑Channel Independent Smart Charger – Professional Capacity Testing with Clear Display

⚠️ Important Notes (Must Read)

1. No Internal Resistance Tester – The “battery internal resistance (mΩ)” value shown on the display is for reference only. It is not a precise measurement from a professional internal resistance meter and should not be used as the sole basis for judging battery health.

2. All Displayed Data Are for Reference – All values shown on the LCD screen (voltage, current, capacity in mAh, internal resistance, percentage, etc.) are reference values during the charging/discharging process. For accurate battery performance data, please use professional testing instruments.

3. Strict Battery Compatibility:

   • ✅ Compatible: Only 3.7V Li‑ion (e.g., 18650, 26650, 14500) and 1.2V Ni‑MH (e.g., AA, AAA) rechargeable batteries.

   • ❌ DO NOT charge: 1.5V lithium batteries, 3.2V LiFePO₄ batteries, IMR 3.8V batteries, or any other types. Placing these into the charger may cause danger.

4. Default Mode: When you insert a battery, the charger automatically enters CHARGE mode and recognises the battery type (displaying Li‑ion 3.7V or Ni‑MH 1.2V) before starting to charge.

🔬 Core Feature: TEST (Capacity Test) Mode

The Lii‑600 is more than just a charger – it is also a professional tool for evaluating battery capacity. With TEST mode, you can scientifically assess the true performance of your batteries.

TEST Mode – Fully Automatic 3‑Step Process:

How to select TEST mode?

1. Insert the battery and connect power.

2. Long‑press the “MODE” touch point (you will hear a “beep”), then short‑press repeatedly until “TEST” appears.

3. Long‑press “CURRENT” to select MANUAL (set your own charge current) or AUTO (system automatically assigns current).

4. After 8 seconds without operation, the TEST cycle starts automatically.

🎮 Four Operating Modes (Independent Channels)

Each of the four channels (CH1–CH4) can be set to a different mode independently, allowing mixed charging and testing simultaneously:

📊 LCD Display Interpretation (Data for Reference Only – Use Professional Instruments for Accuracy)

The Lii‑600 features a large independent LCD screen. Short‑press the 1/2/3/4 touch points to cycle through detailed data for each channel:

• Battery type – Auto‑detected and displayed as Li‑ion 3.7V or Ni‑MH 1.2V.

• Current mode – CHARGE / DISCHARGE / TEST / REPAIR.

• Real‑time voltage (V).

• Charge / discharge capacity (mAh) – the amount of energy charged into or discharged from the battery – a key reference for assessing battery capacity.

• Percentage (%) – estimated charge progress.

• Elapsed time (h) – running time of the current mode.

• Set current (mA) – the working current for that channel.

• Battery internal resistance (mΩ) – for reference only; not an accurate value.

• Temperature (°C) – battery or ambient temperature reference.

End of process: When a channel completes its cycle, the screen shows “End”, the green LED lights up steadily, and a beep sounds.

🖐️ Touch Control Operations

⚙️ Current Level Options

Note for TEST mode: The discharge current is automatically determined by the charge current you set:

• If charge current ≤ 250mA → discharge current = 250mA

• If charge current = 500mA or 1000mA → discharge current = 500mA

• If charge current > 1000mA → discharge current = 750mA

🛡️ Multiple Safety Protections

• Over‑charge and over‑discharge protection

• Short‑circuit protection

• Intelligent temperature control

• 0V battery activation function

• Reverse‑polarity protection (shows “Err”)

• Rejects charging for voltages between 1.65V and 2.2V (recognised as abnormal battery)

• Bad battery detection (shows “Err”)

📦 Specifications

Summary: The Lii‑600 is your reliable assistant for testing battery capacity. Remember: all displayed data are for reference only – for precise capacity evaluation, always use professional equipment. Strictly follow the battery type restrictions to ensure safe operation.
