DescriptionReport this item or sellerLiitoKala Lii‑PD4 4‑Slot Independent Smart Charger – Product Description⚠️ Important Note (Please Read Carefully)This charger is purely a charging device and does NOT have the following functions:❌ Battery capacity testing (discharge to measure capacity)❌ Internal resistance testing❌ Real‑time temperature monitoring / temperature testingDo not expect or mistake this unit for having any of the above measurement capabilities. All data shown during charging (voltage, accumulated capacity, time, etc.) are for operational reference only. For accurate measurements, please use professional instruments.✅ Compatible Battery Types (Only the Following Four)Battery ChemistryNominal VoltageAuto‑DetectionNi‑MH / Ni‑Cd1.2V✅ AutomaticLi‑ion3.7V✅ AutomaticLiFePO₄3.2V⚠️ Manual selection requiredIMR (3.8V high‑voltage Li‑ion)3.8V⚠️ Manual selection required❗ NOT compatible with 1.5V primary (non‑rechargeable) lithium batteries or 1.5V rechargeable lithium batteries (e.g., AA 1.5V Li‑ion). Do not insert them, as they may damage the battery or charger. Physically Compatible Battery SizesLi‑ion series: 26650, 21700 (only flat‑top unprotected versions; button‑top or PCB‑protected cells cannot fit), 20700, 18650, 18490, 18350, 17670, 17500, 16340 (RCR123), 14500, 10440Ni‑MH / Ni‑Cd series: AA, AAA, SC, CNote: For 21700 batteries, any cell with a button top or an added protection circuit (PCB) will exceed the slot length or diameter limits and cannot be inserted. Please use standard flat‑top 21700 cells. LCD Display – What Is Actually ShownEach slot independently displays:Charge percentage: Real‑time continuous readout from 0% to 100% (the progress icon flashes during charging)Battery type: 1.2V Ni‑MH / 3.7V Li‑ion / 3.2V LiFePO₄ / 3.8V IMRReal‑time voltage (V)Accumulated charged capacity (mAh, total charge put into the battery – not a discharge‑tested capacity)Charging time (elapsed time)Current charge current (0.5A / 1A / 2A)When charging is complete, 100% is shown and “End” appears in the lower‑right corner.With no battery inserted, the screen shows “null” and turns off after 30 seconds. Operation (Simple and Intuitive)Four independent slots, each with its own Mode button.After inserting a battery, the screen flashes the detected battery type:For 3.7V Li‑ion or 1.2V Ni‑MH → the system automatically recognises them and starts charging after 5 seconds.For 3.2V (LiFePO₄) or 3.8V (IMR) → within 5 seconds, short‑press the Mode button for that slot to cycle to the correct voltage. After 5 seconds the selection is locked and charging begins.During charging, neither short‑press nor long‑press of the Mode button can change the battery type or charging mode. To change the setting, you must disconnect power and restart the charger.⚡ Charging Current (Intelligent Distribution)SlotCurrent CapabilitySlots 1, 2, 3500mA or 1000mA (automatically assigned)Slot #4 (dedicated)Supports up to 2000mA (2A) – but only when this slot is used alone (only one battery inserted, placed in slot #4). If other slots are also occupied, the system adjusts currents based on total load, and slot #4 may be reduced to 1000mA or 500mA.In short: to get 2A fast charging, place only one battery in slot #4. Input PowerStandard: AC 100‑240V 50/60Hz built‑in power supply (plug directly into mains)Optional: DC 12V 1A adapter (requires ≥1A output)️ Multiple Safety ProtectionsOver‑charge protection (constant‑current constant‑voltage charging, cut‑off current <100mA)Over‑discharge protectionShort‑circuit protectionReverse‑polarity protection (battery inserted backwards will not charge)Smart detection of faulty batteries0V battery activation (batteries in the 1.65V–2.20V range are not charged, but a tiny activation current is applied) SpecificationsDimensions: 147mm × 100mm × 37mm (L × W × H)Weight: approx. 221g (without power cord) Usage TipsThe charger will become slightly warm during operation – this is normal. Place it in a well‑ventilated area.After charging is complete, unplug the power cord and remove the batteries.For indoor use only. Keep away from moisture.
