It’s interesting as the second photo shows a lower voltage than the first which is obviously taken later. It looks to be charging it still from the increase in voltage
Ah I didn’t order the pictures correctly in my post, the 1st picture with the higher voltage is the more recent one. Just an update, it did show one bar of capacity at 3.9v and then three bars at 4.08v until I finally took it out of the charger. Not sure why the charger was reading it that way - can’t tell if it was that specific battery or not. I have a bunch of 30Qs coming in soon, will see if they encounter the same issue.
I ordered it from illumn.com (Illumination Supply LLC) last year.
It had the same issue, however, after an hour or so when it reached 3.90v the charger showed a bar of charge capacity. A redditor suggested that for some reason the charger might be “conservative” and read low 3 volts as not charged. Sounds plausible, but I did try charging on a Nitecore D4 as well which showed the same 3.08v and zero bar capacity (“empty”). I left it in the charger until it showed 4.08v and it actually displayed three bars charge capacity - not sure why the 30Q would behave the same in two different chargers and show “empty” capacity at 3.08v, but it did seem to charge ok.
Haven’t done any extensive testing yet, I do have a few 30Q batteries coming soon from 18650batterystore, will see if the issue is duplicated with those. Will probably drain a Sony/Murata VTC6 (green battery pictured) and an LG as well and see if they run into the same issue.
Edit: Not sure when it changed to two bars, it showed one bar at 3.9v and three bars when I took it out at 4.08v.
