Nitecore UMS2 USC Quick Charger 3A Dual-Slot LI-ION NIMH Battery Charger

The Nitecore UMS2 is a dual slot USB battery charger with a total maximum output of 4000mA and an impressive single slot maximum of 3000mA. The charger is optimised for IMR batteries and monitors the entire charging process, ensuring the cut-off voltage is always within safe limits. When the battery is inserted, the charger will automatically detect the cell and select betwen the 3 charging modes (CC, CV and -dV/dt).

The UMS2 features an LCD display for real time charging information, including internal resistance and battery health detection. A short press on the 'V' switch will cycle through the charging information, including the charged volume, charging time, charging current, battery voltage, battery type, cut-off voltage and charging mode. If desired, the charging parameters can be set manually. Long press the 'C' button to enter the charging setting mode.

The Nitecore charger features over-discharged IMR battery restoration, over-discharged Li-ion battery activation, anti-short circuiting and reverse polarity protection to keep your batteries in the best health for as long as possible.

The Nitecore UMS2 is compatible with the following IMR/Li-ion/LiFePO4 batteries: 10440, 14500, 14650, 16500, 16340 (RCR123), 16650, 17350, 17500, 17650, 17670, 17700, 18350, 18490, 18500, 18650, 18700, 20700, 21700, 22500, 22650, 25500, 26500, 26650, 26700 and the following NiMH/NiCd batteries: AA, AAA, AAAA, C and D.
