The NiteCore UM4 is an intelligent, universal battery charger with space for four batteries. This charger can not only charge Li-Ion, Ni-MH, Ni-Cd and LiFePO4 batteries, but also the high-quality IMR batteries are no problem. Four batteries can be charged simultaneously, with both charging cycles being independently controlled. Each shaft has a charging capacity of 1500 mA. At this speed, a 3500mAh battery is charged to 80% within two hours.
The LCD screen shows information about, among other things, the battery level, the charging voltage and the charging time. This is displayed individually for each battery. The NiteCore UM4 is also characterized by a high degree of safety. It detects non-rechargeable batteries on its own. The charger also has a protection against incorrectly placed batteries. This prevents safety problems. The charger stops as soon as the battery is fully charged.
