Yesterday evening I went through some of my flashlights to check the batteries. I took the EagleTac MX25L3 in the hand and it felt by the weight like the cells were in it. I tried to switch it on but no light. I asked my self if it has a lock out function activated which I could have forgotten. I removed the tailcap and yes; three cells were in it. Then I placed the cells in the charger and got a shock. How could this be possible? I knew about parasitic drain but such a huge and only for one of the cells?
Here is a picture from when I first placed the cells in the charger.
After a while the voltage had raise to 0,4V on the cell to left and a marginial increase than initial for the other two also. I interrupted the recharge for a walk and when I came back and started the charging again it showed this:
I assume that the charger gave the wrong information first time(probably a contact issue) and all cells were around 3V(a protected cell can't be discharged to 0,2V and if so it could not restore to be ok again, right?). But if so: why didn't the light turn on?
Now all cells are fully charged to 4,2V and the light works properly.
