Question on NiteCore UMS4 Charger

Does anyone have this charger? I recently purchased the UMS4 charger and noticed the display screen stays on without batteries in the slots. Is this correct? My other NiteCore chargers (D4s & i2s) go blank when the batteries are removed.

I have reached out to NiteCore but they are away until the 10th for the New Year. There is nothing in the manual as well except there is an energy saving mode where the screen is supposed to go dim after 3 minutes if no buttons are pushed while charging.

Thanks for any help.


This doesn’t answer your question but I have the NiteCore SC2 and it’s display always remains on when the slots are empty. I doubt it’s anything to be concerned with.


I appreciate that. Thanks :+1:
