I have the Fenix E15 that I use a 16340 battery. I'm curious as to when users of 3.7V batteries decide to charge them. I checked the voltage, and it measures 3.36. Since it's a dual power use light, I still have 4 modes, but it will no longer output 450 lumens. I can tell a difference in each mode, so I'm assuming turbo is now 270 lumens if I was using a cr123. This really doesn't bother me with less output on turbo. I guess my question is what do you do? Do you keep using it as is until maybe one or two modes work? Or, would you replace/charge the battery to have the highest output? Is there any harm to topping these batteries off, or fully depleting them from use? I'm using Fenix batteries.
