The Nitecore UM2 Dual Bay USB Battery Charger is an intelligent USB dual-slot charger, capable of charging 2 batteries simultaneously and controlling each slot independently. 

The LCD screen can display a real-time information of Charging Current, Battery Voltage, Charged Volume and Charging time. It can enable an automatic detection of battery power level and automatic selection of the appropriate voltage and charging mode and automatic selection between 3 charging modes (CC, CV and -dV/dt). The charging parameters can be set manually to meet various charging needs.

The UM2 is compatible with 3.6V/3.7V Li-ion rechargeable batteries, 3.8V Li-ion rechargeable batteries, 1.2V Ni-MH/Ni-Cd rechargeable batteries and 3.2V LiFePO4 batteries.

Multiple safeguards ensure the safe charging process, including anti-short circuiting and reverse polarity protection, overtime charging protection, over-discharged Li-ion battery activation and over-discharged IMR battery restoration.

Please check battery compatibility below before purchasing.
