The Opus BT-C3100 Intelligent Li-ion/NiCd/NiMH battery charger/analyzer is one of the first battery charger/analyzers that can (quick-)test/refresh/charge/discharge li-ion batteries and do that for NiCd/NiMH batteries too. Charging Cell Type: Ni-MH, NiCd, Lithium Ion,Designed for AA ( LR6 ) and AAA ( LR3 NiCd, NiMH or 3.7V Li-ion rechargeable batteries in size type of 10440, 14500, 16340, 17335, 17500, 18490, 17670, 18650
Note: Battery not included,The charging current can be selected to be 200mA, 300mA, 500mA, 700mA or 1000mA (1500mA and 2000mA can only be applied when only slot 1 or 4 is selected). Default discharging current is 500mA
It provides four independent charging slots for rechargeable batteries. The charger can charge batteries of different types and sizes and with different capacities at the same time
Four Working Mode Available at User's Choice: Charge, Discharge, Test, Quick Test and Refresh,The charger also includes overheat detection to protect rechargeable batteries and charger itself from overheating
Better safety feature: PCB temperature was used to in controlling fan on / off only with 2.0V, now this function is enhanced so that temperature is monitored for entering thermal shutdown mode when excessive high temperature is reached.

The product is intended to charge and discharge NiCd, NiMH or 3.7v Li-ion rechargeable batteries in size type of 16340, 10440, 14500, 16340, 18500, 18650, 26650, 26500. It provides four independent charging slots for rechargeable batteries. The charger can also optimize and test the maximum capacity of the rechargeable batteries. Each charging slot has its own display to show various information, such as, charging current, battery voltage, charged capacity, battery internal resistance and elapsed charging time.
