I’ve been using my Nitecore D2 as my “go-to” charger for 3 or 4 years. It has performed flawlessly when charging a variety of 14500 and 18650 li-ion cells, as well as AA Ni-mh cells.
Earlier this week I plugged it in, and instead of the normal display, I only see the greenish backlight illumination - no data or symbols at all - a blank screen.
The only hint I’ve had of anything out of the ordinary is that I recently noticed that I had to plug the charger in and let it initialize before inserting any batteries. Previously, I believe I could put the batteries in before plugging in the charger, and it would still power up OK. Not sure if this is related to my current issue with the display.
Has anyone else experienced a similar failure of this model? Is it common?
