Lii-D4XL 4-Slot Independent Smart Charger – Product Details ⚠️ Important Notice – Please Read FirstThis charger is a dedicated charging device. It does NOT have any capacity test, internal resistance test, or temperature test functions.The LCD display will NOT show internal resistance values, discharge‑based capacity percentages, or battery temperature.The charge percentage and charged capacity (mAh) shown on the screen are real‑time charging progress and the amount of electricity already put into the battery – these data are accurate as charging statistics, but they are for reference only.Please do not misinterpret them as battery health or actual discharge capacity test results.Compatible Battery Types (Strictly Limited)This charger only supports the following rechargeable batteries:Ni-MH / Ni-Cd : 1.2VLi-ion : 3.7V (standard lithium‑ion)LiFePO₄ : 3.2V (lithium iron phosphate)IMR : 3.8V (e.g., Li‑ion 3.80V)❌ DO NOT charge 1.5V primary lithium batteries or 1.5V rechargeable lithium batteries (such as AA 1.5V constant‑voltage Li‑ion). Inserting them may damage the charger or the battery.Key Features1. Four Independent Slots with Micro‑computer ControlEach slot operates independently. You can charge up to four different battery types/sizes simultaneously without interference.2. Automatic Recognition & Manual SelectionWhen a battery is inserted, the charger automatically detects 3.7V Li‑ion and 1.2V Ni‑MH batteries and applies the correct charging voltage by default.For 3.2V (LiFePO₄) and 3.8V (IMR) batteries, you must press the Mode button within 5 seconds after power‑on to manually select the corresponding voltage type. The charger will then start charging with the proper voltage.3. Three Selectable Charging CurrentsWithin 5 seconds of inserting a battery, press the CURRENT button to cycle through three current levels:300mA – for small‑capacity cells (e.g., 10440, 16340)500mA – for medium‑capacity cells (e.g., 14500, AA Ni‑MH)1000mA – for large‑capacity cells (e.g., 18650, 21700, 26650)Always refer to your battery’s recommended charging current and do not exceed its maximum rating.4. Dedicated 9V Battery Charging PortsTwo ports (located on both sides of the LCD display) allow charging of two 9V Ni‑MH/Ni‑Cd batteries simultaneously. Each port provides ~85mA charging current. A red LED indicates charging; green indicates fully charged or standby.LCD Display InformationAfter connecting power, the screen lights up fully for 3 seconds. If no battery is inserted, it shows null and turns off after 30 seconds of inactivity.When a battery is detected, the corresponding slot displays:The battery type icon (e.g., Li‑ion 3.70V or NiMH 1.2V) flashes – you can press the Mode button within 5 seconds to change the type if needed.Once the type is confirmed, the charge percentage symbol flashes, indicating that charging is in progress.Real‑time readouts include:Charge percentage (0% – 100%)Current voltage (V)Charged capacity (mAh) – the amount of electricity already deliveredWhen charging is complete, the percentage shows 100% and “End” appears in the lower right corner.⚠️ The display does NOT show internal resistance, temperature, discharge test data, nor does it display charging time (duration). Please be aware of this.Safety ProtectionsOver‑charge protection – automatically stops when fully chargedOver‑discharge recovery – activates with a small current for low‑voltage batteriesShort‑circuit protection – cuts off power immediately if short is detectedReverse polarity protection – prevents charging when battery is inserted backwardsDefective battery detection – identifies abnormal batteries and refuses to charge0V voltage activation – provides a trickle current to activate 0‑volt batteries; however, batteries in the 1.65V – 2.20V range will NOT be charged (only a tiny activation current is applied)Electrical SpecificationsParameterSpecificationInput PowerAC 110‑240V 50/60Hz (built‑in power supply, included)DC 12V ≥2A (optional)Output VoltageLi‑ion: 4.2V / IMR: 4.35V / LiFePO₄: 3.65V / NiMH/Ni‑Cd: 1.48VCharging Current (per slot)1000mA / 500mA / 300mA selectable (independent per slot)9V Charging Current85mA × 2Cut‑off CurrentStandby Current (no load)Compatible Battery Models (Physical Sizes)TypeSupported ModelsLi‑ion / IMR / LiFePO₄26650, 21700, 20700, 18650, 18490, 18350, 17670, 17500, 16340(RCR123), 14500, 10440Ni‑MH / Ni‑CdAA, AAA, SC, CProduct DimensionsDimensions : 136mm × 169mm × 47mm (L × W × H)Usage Precautions (from the manual)Only use with cylindrical rechargeable batteries. Never charge primary (non‑rechargeable) or unknown‑type batteries.Check the recommended charging current for your battery and do not exceed it.If using a 12V DC adapter, ensure it can supply at least 2A.The charger may become hot during operation – avoid touching it and keep it in a well‑ventilated area.Always unplug the power supply and remove batteries after use.Use only indoors in a dry environment.Display data are for reference only; for precise measurements, please use professional instruments.Final Note: The Lii‑D4XL is a dedicated, safe, and reliable smart charger focusing on constant‑current / constant‑voltage charging for the four listed battery types, with clear real‑time charging progress and capacity readouts. Please use it as a charger – do not expect it to function as a battery tester.
