The Nitecore UM2 Intelligent USB Dual-Slot Battery Charger is an efficient charger for high-drain battery cells of various capacities and sizes (18650 / 20700 / 21700 / 26650), alongside automatic type detection, various inputs, and new restoration mode. The special restoration mode can potentially revive overdrawn or drained Li-ion batteries, extending the life of them. With up to 1500mAh charging speed per slot, the Nitecore UM2 has two bays to automatically detect Li-ion, IMR, Ni-MH, and other various battery types and apply the proper charging settings optimal to maintaining battery health. Furthermore, the Nitecore UM2 has a slew of internal protections to guard against failing or damaging the batteries while also maintaining optimal heat dissipation from the durable and flame retardant PC chassis.
CHARGING PROGRAM SPECIALLY OPTIMIZED FOR IMR BATTERIES - UM2 incorporates an optimized IMR battery charging program, which is able to monitor the entire charging process, ensuring that the cut-off voltage is always within safe limits to extend the lifespan of the batteries.

IMPORTANT NOTE: Understanding how to handle and care for Lithium-ion batteries is very important and should always be practiced. Lithium type batteries are very sensitive to charging characteristics and may explode or flame if mishandled. DO NOT charge your batteries overnight or while unattended for a prolonged period of time! Always charge your batteries in a fire-proof surface/area and DO NOT expose them to high temperatures (e.g. inside your car). DO NOT expose the battery's terminals to metal objects or immerse in water/liquid. We are not responsible for any damage if there is any misuse, abuse or modification of the batteries and/or chargers in any shape or form (including operating while wired in series). Furthermore, Electric Vapor Cigarettes LLC (a.k.a. EVcigarettes.com) will not be held responsible or liable for any injury, property damage, or defect that is caused by misuse, abuse or modification of Lithium batteries and/or chargers.
