LCD Universal Charger for Li-Ion battery 3.7V/7.4V voltage and polarity Auto Detection|SC-M20 LCD M20-LCD Specification Intelligent auto reverse-connect protection device auto detects the polarity of the inserted battery Battery type: 3.7V (1 cell) / 7.4V (2 cell) rechargeable Li-Ion battery pack Protection: short circuit, defective battery detection Power Input: 12 VDC 1A / USB Input: 5VDC 1A Charger mode: constant current first then constant voltage ( CC / CV ) Cut-off voltage: 3.7V battery pack is 4.2V, 7.4V battery pack is 8.4V Charging current at 12V 1000mA input : 3.7V battery pack is 700mA, 7.4V battery pack is 1000mA maximum at constant current mode Charging current at 5V 1000mA Input : 3.7V battery pack is 700mA, 7.4V battery pack is 400mA maximum at constant current mode Standby Current: 60mA for 5V input,100mA for 12V input Operating temperature: 0°C~ +55°C Storage temperature: -25°C ~ +70°C Cut Off termination: Fixed Voltage Size:240*140*70mm Weight:260g Operating Instruction Connect the power to the charger using the supplied AC power adaptor or DC car cigarette lighter adaptor, the red LED on the top left side indicates a ready status, insertion of the rechargeable battery. *The charger has 2 flexible contact pins, which must be adjusted for the chosen rechargeable battery pack. *Start by fixing the rechargeable battery pack with the clamping device a little distance from the contact pins of the charger. *Now slide the contact pins in such a way that they line up with the contacts of the rechargeable battery pack. *Next, take out the rechargeable battery pack and clamp it again, but this time ensure that the contact pins of the charger and battery pack are touching. *The charger will automatically adjust to the polarity of the pack so connection can be made either way. *If the battery pack has more than two connections, ensure that the + and ?C contacts are chosen. *Once the connecting has been verified by the charger the LED will start running up to indicate that the charging process has started. After charging is completed the LED stops running and green LED stays on. *If red and green LED flash alternatively after a period, the rechargeable battery may be faulty and need replacing. *Please pay attention to insert with the correct + and ?C contact. *The charge will turn off automatically when the cells are full owing to the function of the microprocessor. *If for any reason the cells do not exhibit the right ??battery full?? characteristics, the integrated safety timer Terminates the charging procedure after 8 hour
