【Product Description】
The Ultimate Professional Charging & Testing Station. The LiitoKala Lii-600 is the flagship 4-slot smart charger that goes far beyond simple charging. It combines a high-definition touch screen, blazing 3A super fast charging, professional-grade internal resistance testing, capacity grading, and battery repair features all in one durable unit.
Equipped with a powerful microcomputer and a sensitive touch panel, the Lii-600 automatically identifies battery chemistry (3.6/3.7V Li-ion, 1.2V NiMH/NiCd) and voltage. It supports four slots working independently, allowing you to charge, test, and repair different types of batteries simultaneously.
Its most impressive feature is the 3A charging current. All four slots can charge at 3A simultaneously (in AUTO mode), meaning four 5000mAh batteries can be fully charged in just over one hour! The Lii-600 also features a built-in Internal Resistance Tester (mΩ) that instantly reveals the health of your cells, helping you identify aging, degraded, or counterfeit batteries.
Plug Options: This charger comes in US, EU, and UK plug variants. Please select the correct plug type for your region before placing your order.

【Key Features】
-
Blazing Fast 3A Super Charging: All 4 slots charge simultaneously at 3A (manual mode). Fully charge a set of 4x 5000mAh Li-ion batteries in just over 1 hour, saving you significant time.
-
Professional Internal Resistance (mΩ) Tester: Instantly measures battery resistance with an error value of ≤30%. Lower mΩ means a healthier, higher-discharge battery. Perfect for identifying bad cells.
-
Accurate Capacity Testing (TEST Mode): Automatically performs a Charge-Discharge-Charge cycle (250mA/500mA/750mA) to measure the true mAh capacity, exposing fake or degraded cells.
-
Smart Touch Screen Control: High-sensitivity touch buttons replace mechanical switches, offering a modern, durable, and easy-to-use interface.
-
Battery Repair (REPAIR Mode): Automatically cycles batteries to remove the memory effect in NiMH/NiCd or revive over-discharged (0V) batteries, bringing them back to peak performance.
-
Real-Time Temperature Monitoring: Built-in temperature sensor displays real-time cell temperature. If it exceeds 65℃, the charger automatically reduces current to protect your battery.
-
Multi-Chemistry & Wide Size Support: Compatible with 3.6/3.7V Li-ion (18650, 21700, 26650) and 1.2V NiMH (AA/AAA/A/SC/C/D). The extended slots fit batteries up to 73mm, including protected 21700 cells.

【Frequently Asked Questions (FAQ)】
Q1: What is the difference between AUTO and MANUAL modes?
A1: In AUTO mode, the Lii-600 automatically detects battery resistance and capacity, assigning a safe current (up to 3A) to charge the battery as fast as possible. In MANUAL mode, you can manually select the charging current (from 250mA to 3000mA) to suit specific battery sizes and conditions.
Q2: Why is the internal resistance (mΩ) test so important?
A2: Internal resistance is the primary indicator of a battery's health. Low resistance means high discharge capability and minimal heat generation. Higher resistance (often found in old or fake cells) means the battery will drop voltage quickly and may overheat under load. The Lii-600 gives you a professional-grade measurement to assess this.
Q3: Can I charge 4 different types of batteries at the same time?
A3: Yes. The 4 independent slots each have their own smart identification. You can charge a 3.7V 18650, a 3.7V 21700, a 1.2V AA NiMH, and a 1.2V AAA NiMH simultaneously. Each slot receives the appropriate charging current.
Q4: What is the REPAIR function?
A4: The REPAIR mode is a powerful tool for restoring old batteries. It automatically discharges and recharges the battery through several cycles, which helps break down the "memory effect" in NiMH/NiCd batteries and can revive over-discharged Li-ion cells.
Q5: How do I know the temperature of my battery?
A5: The Lii-600 has a built-in temperature sensor. When charging or testing, the current battery temperature will be displayed on the screen. If the temperature rises above 65℃ during charging, the charger will automatically lower the current to ensure safe operation.
