IMPORTANT NOTICE (PLEASE READ FIRST)This charger does NOT have capacity testing, internal resistance testing, or temperature testing functions. The LCD screen will NOT display battery capacity (mAh), internal resistance (mΩ), or temperature (°C) data.The internal resistance value shown on the screen is only a dynamic reference during charging – it is not a precise measurement and should not be used as a performance indicator. For accurate data, please use dedicated instruments.When a battery is inserted into the slot, the charger will automatically recognise the battery type (e.g., 3.70V Li‑ion, 1.20V Ni‑MH/Ni‑Cd, etc.) and begin charging.However, for more accurate charging results, we recommend that you manually select the corresponding charging voltage according to the battery's actual rated voltage by pressing the MODE button (e.g., LiFePO₄ 3.20V, IMR 3.80V) – this avoids any deviation that may occur with automatic detection.This charger supports ONLY the following battery types: 3.70V Li‑ion, 3.20V LiFePO₄, 3.80V IMR, 1.20V Ni‑MH/Ni‑Cd, and 9V Ni‑MH.DO NOT charge 1.5V batteries (e.g., alkaline batteries, 1.5V lithium primary cells, etc.) – doing so may cause hazards.Lii-S12 12‑Slot Smart Charger – Mixed Battery Charging · Independent LCD DisplayProduct OverviewThe Lii‑S12 is a multi‑slot smart charger with a microcontroller management system, supporting 12 independent charging slots. Its standout feature is the ability to charge multiple battery types simultaneously, and it also supports 9V Ni‑MH rechargeable batteries (prismatic type). The LCD screen shows real‑time charging progress, voltage, percentage, and battery type information. With easy operation and comprehensive safety protections, it is ideal for everyday use by households and electronics enthusiasts.Key Features Mixed Charging of Multiple Battery Types (12 Independent Slots)Supports simultaneous charging of cylindrical batteries of different chemistries in separate slots without interference.Slots 1, 3, 5, 7, 9, and 11 can deliver up to 1.0A charging current; all other slots (and Ni‑MH/Ni‑Cd batteries) charge at 0.5A.Dedicated 9V Ni‑MH slots: independent 85mA constant‑current charging for special battery needs. Dual Visual Feedback – LCD Display & Indicator LEDsStandby: screen shows "null"; the 9V slot indicator LED stays green, ready for charging.After battery insertion (within 8 seconds):The screen displays: battery icon, slot number (CH), battery type (auto‑detected or manually selected), charging current (A), battery voltage (V), and charge percentage (%).After the battery type is confirmed, the type icon blinks 9 times (approx. 9 seconds), then normal charging begins – the battery icon rises in a staircase pattern, and the corresponding slot LED turns red.Charge complete: screen shows 100%, battery icon full and static, slot LED turns green.Fault alerts:For cylindrical battery slots – short circuit / reverse polarity → screen shows "CH+Err", battery icon blinks, and the slot LED flashes red.For 9V slot – both indicator LEDs turn solid red (screen display remains unchanged). Intelligent Battery Detection & Manual SelectionAuto‑detection: by default, the system automatically recognises 3.70V Li‑ion and 1.20V Ni‑MH/Ni‑Cd batteries.Manual selection (MODE button): allows switching to LiFePO₄ (3.20V) or IMR (3.80V) battery modes.9V Ni‑MH batteries: charging starts immediately; no data is shown on the screen (this is normal).️ Multiple Safety ProtectionsOver‑charge protection / Over‑discharge protection / Short‑circuit protection / Reverse‑polarity protectionBad battery detection: automatically identifies and rejects abnormal batteries0V voltage activation: attempts to recover deeply discharged batteries with a trickle current (voltages between 1.65V and 2.20V are not charged normally, only activation current is supplied)Constant Current / Constant Voltage (CC/CV) charging with a cut‑off current of 100mA, ensuring safe charging and extended battery lifeButton Operation GuideButtonFunctionMODEWithin 8 seconds of inserting a battery, press to cycle through battery types (3.70V / 3.80V / 3.20V). During charging, long‑press to reselect type (previous data will not be saved).1‑4 / 5‑8 / 9‑12 (query keys)Short‑press to view charging status for the corresponding 4 slots (scrolls from CH1 to CH12). Long‑press to keep the backlight always on; press and hold again to cancel always‑on mode.Electrical Specifications & Compatible BatteriesParameterSpecificationInput PowerDC 12.0V / 4.0A minimum (requires suitable adapter)Output VoltageLi‑ion 4.20V / IMR 4.35V / LiFePO₄ 3.65V / Ni‑MH/Ni‑Cd 1.48V / 9V Ni‑MH 9.0VOutput Current• Li‑ion/IMR/LiFePO₄: 1.0A×6 (slots 1,3,5,7,9,11), 0.5A×12• Ni‑MH/Ni‑Cd: 0.5A×12• 9V Ni‑MH: 85mA×2Standby Current＜50mACompatible Cylindrical Battery Models26650 / 21700 / 20700 / 18650 / 18490 / 18350 / 17670 / 17500 / 16340 (RCR123) / 14500 / 10440Ni‑MH / Ni‑Cd: AA / AAA / SC / C⚠️ Important ReminderThis charger supports ONLY the following battery types:✅ 3.70V Li‑ion✅ 3.20V LiFePO₄✅ 3.80V IMR (Li‑ion)✅ 1.20V Ni‑MH / Ni‑Cd✅ 9V Ni‑MH❌ DO NOT charge 1.5V batteries (e.g., disposable alkaline batteries, 1.5V lithium primary cells, etc.) – doing so may cause hazards.Usage InstructionsUse a DC 12.0V / ≥4.0A power adapter.The charger may become warm during operation; keep it out of children's reach and use only indoors at room temperature.After use, unplug the power adapter and remove all batteries.Product DimensionsDimensions: 287.0mm × 142.5mm × 35.0mm (L × W × H)Friendly reminder: Please read the user manual carefully before use, ensure the battery type and charging parameters match, and prioritise safety at all times.
