Nitecore UM4 Charger

Description

The Nitecore UM4 charger has a maximum output of 3,000mA (1,500mA per single slot), when used with a quick charge power source (9V/2A). At 1,500mA it takes approximately 2 hours to fully charge a 3500mAh 18650 battery. Each Nitecore UM4 is supplied with a USB lead only, so the quick charge power source is required to be purchased separately. 

The UM4 incorporates an optimised IMR battery charging program, which is able to monitor the entire charging process., ensuring that the cut-off voltage is always within safe limits. 

An LCD display shows real time charging information for the two bays including: charged volume, charging time, charging current battery voltage and battery type. UM4 will automatically select between 3 charging modes (CC, CV and -dV/dt) according to the battery type and capacity.

Other features include over-discharged IMR battery restoration as well as over discharged Li-ion battery activation.
