Try to check your Fenix tailcaps. I had 4 (L1D, L2D, P2D and P3D,all Cree versions) of them and have noticed that there was a resistance between the tailcap body and the spring contact. Measured resistance is not the same but, some went as low as 50K ohm. This translates to 0.12mA of leakage current for a P3D. This means that your fresh CR123's would just drain out in less than a year without using it.
After taking them apart, it was traced that the leakage was caused by the rubber o-ring. The more you tighten the aluminum retaining ring, the lower is the resistance. I 1st suspected it was moisture accumulation on the rubber so, I thoroughly cleaned them with water or alcohol but, leakage still persists. I believe this problem is not only on what I have since I already have 4 of them and all have similar problems. Although, for lower battery voltages like the L1D, this leakage will become so negligible, it still wouldn't feel right knowing something is draining your battery power.
I don't know Fenix quality control engineers were aware about this. What I did was that I wrapped teflon tape around the o-ring to fix the problem.
