What voltage is still usable??? or ok for a cr123 primary battery.
The reason i ask is on my pd 30 it flashes when low, my gf ex10 gets super dim so when its low its obvious usualy about 2.9volts.
My aw rechargeble have set power levels%life acording to aw sales page at set voltages so I know when to charge or stop using etc.
But in my tk 30 its voltage range is 3v to 12v I will at a later date be using 18650 x2 in it so no probs there but for the mean time I am useing 4x 123 primary they are now getting down to 2.91 volts each and there seems to be no sign of poor performance yet.
So what voltage should I run the primary 123's down to in this light or in general I also under stand there are lights used as battery vampires to get all you can out of a cell.
