See mine were 1.4 1,5 and 0.0. I took bad cells out replaced it with a dummy and it ran for another 9 hours??
 
Put all 3 in the tube and with tailcap off check voltage you know black on back of battery red on inside of tube. Bare metal. Sorry if I’m insulting you. I’m sure you know how to do it
 
Well if your voltage is that yes but I’m betting if you check them in the tube it might be different

Lol also might of mixed up red and black in that description. If there’s a -sign in front I did😂😂
 
If you bypass the switch by putting probe on back of cell and touch that to bare tube does she light?
 
Then that’s all she got. That voltage your at now is low limit of what your module will run at. They are all probably a little different. I’ll try a single 123 when I get home. See if she lights.
 
These might shut down at 3.5 volts or so. Anyone try a single 123 yet?


I've got one rolling. Almost 10 hours in, at around 13 lumens. Average around 15 lumens so far.

Single 16650 is almost at 40 hrs but is down to sub-lumen level. 0.01 lumen territory

3x AA L91 still going strong, 20 lumens 37 hours.
