Nitecore UM2 Dual Slot USB Charger for AA/AAA/18650 Battery

The Nitecore UM2 is an intelligent USB charger with a total maximum output of 3000mA, offering speedy charging for your batteries. Please note, in order to achieve the maximum charging speed a 9V 2A QC 2.0 charging adapter must be used.

The charger features a charging programme specially optimised for IMR batteries which monitors the entire charging process, ensuring that the cut-off voltage is always within safe limits to extend the lifespan of the battery. Per single slot the UM2 has a maximum output of 1500mA, which means a 3500mAh 18650 battery takes approximately 2 hours to reach 80% charge. 

The Nitecore UM2 has an LCD display which relays real-time charging information. A short press on the 'V' button will cycle through details on the charged volume and charging time, charging current and battery voltage, battery type, cut-off voltage and charging mode. The charger will automatically select from 3 charging modes when the battery is inserted, according to the battery type and capacity. Alternatively, the charging parameters can be set manually to meet various charging needs; long press the 'C' button to enter the charging setting mode. 

The charger offers over-discharged IMR battery restoration. When an over-discharged IMR battery is inserted, the screen will show 'EE EE'; simply long press the 'V' button to enter restoration mode. The screen will also display 'EE EE' if a short-circuited battery is inserted or the cell is the wrong way round.
