Lii-100B Single-Slot Smart Charger – Product Details (English)⚠️ Important NoticeThis charger is a pure charging device. It does NOT have any functions for capacity testing, internal resistance measurement, temperature monitoring, or any battery health diagnostics. The LED indicators only show charging progress (25%/50%/75%/100%) and do not provide voltage, capacity, or internal resistance values. We state this clearly to avoid any misunderstanding – no false advertising.Product OverviewThe Lii-100B is a single-slot multi-functional smart charger powered via Micro USB DC 5V input. It supports automatic identification and manual selection of charging modes for various cylindrical rechargeable batteries. Built‑in LED indicators display real‑time charging progress, and a 5V/100mA USB output port is available for emergency power supply to small devices.Core Functions (All Genuine)Single‑slot independent charging with Micro USB input, plug‑and‑playTwo selectable charging currents: 500mA / 1000mA (long‑press the SELECT button for 3 seconds to switch)4‑step LED progress display: 25% → 50% → 75% → 100%Automatic battery type recognition:Automatically identifies 1.2V Ni‑MH and 3.7V Li‑ionManual selection for 3.2V LiFePO₄ and 3.85V Li‑ion (IMR high‑voltage) batteries0V battery activation (attempts to revive over‑discharged protected cells)Multiple protections: over‑charge, over‑discharge, short‑circuit, reverse‑polarity, and defective battery detection (LED flashes when a bad battery is inserted and charging will not start)Constant Current / Constant Voltage (CC/CV) charging with cut‑off current < 100mA for safe termination5V/100mA USB output (emergency low‑power supply)Compatible Battery Types (Important)Battery TypeNominal VoltageRecognitionSupportedNi‑MH1.2VAutomatic✅ YesLi‑ion3.7VAutomatic✅ YesLiFePO₄3.2VManual✅ YesHigh‑voltage Li‑ion (IMR / 3.85V)3.85VManual✅ Yes1.5V Li‑ion (constant‑voltage 1.5V)1.5V—❌ Not supported1.6V – 2.2V batteries——❌ Not supportedPlease note: This charger cannot charge 1.5V constant‑voltage lithium batteries. Do not insert them, as they may not be recognised or could cause damage.Compatible Battery Sizes (Chargeable)Supports the following cylindrical cells (with positive/negative button tops or flat tops, within the slot length range):18650, 26650, 18490, 18350, 17670, 17500, 16340 (RCR123), 14500, 10440❌ Does NOT support 21700 batteries (length/diameter exceed the slot’s physical range – do not attempt).Operating InstructionsInsert battery: The charger automatically recognises 1.2V/3.7V cells; the LED shows the current mode.Switch current: Long‑press the SELECT button for 3 seconds to toggle between 500mA and 1000mA (adjustable at any time).Manually select special batteries: Short‑press the SELECT button to cycle through modes (including LiFePO₄ 3.2V and 3.85V Li‑ion). After selection, charging will start automatically in 5 seconds.Check battery type: During charging, short‑press the SELECT button; the LED will flash to indicate the currently recognised/manually selected type.USB output: Connect a USB cable (with no battery inserted) to get 5V/100mA output for temporary low‑power devices.Electrical SpecificationsParameterValueInputMicro USB DC 5V / 1AOutput voltage (charging)4.2V ±1%Output voltage (USB out)5VCharging current (selectable)500mA / 1000mACut‑off current< 100mA (constant‑voltage stage auto‑termination)Standby current≤ 15mAUSB output current5V / 100mADimensions & WeightDimensions: 112mm × 37mm × 32mm (L × W × H)Net weight: approx. 45g (without USB cable and batteries)Included in the package: Charger ×1, Micro USB cable ×1 (approx. 17g)Important PrecautionsUse a 5V/1A or higher USB power adapter (e.g., mobile phone charger) to supply power. Insufficient current may prevent the charger from reaching the 1000mA setting.If a defective battery is inserted or polarity is reversed, the charger will not respond or the LED will flash – this is normal protection behaviour.3.2V LiFePO₄ and 3.85V Li‑ion batteries MUST be manually selected; otherwise, they will be charged as default 3.7V, which may cause over‑charge risk.This product has no testing functions (capacity, internal resistance, temperature, etc.) – it is designed solely for safe charging.After‑Sales SupportDesigned and made in China. For further technical assistance or questions, please contact your local distributor.Please read the manual carefully, select the correct battery mode, and use safely.
