Nitecore UM2 Intelligent USB QC Charger
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.

IMR/Li-ion/LiFePO4 batteries: 10440, 14500, 14650, 16500, 16340 (RCR123),
