Ziemas, I still have the same batteries as when I started the thread, but I did buy the hybrid ReCykos I mentioned in post #20.

I took my time trying my old batteries out in actual use to see how they do. I also measured on-the-shelf voltage drops while I was at it. My old no-brands lost 8-9% of voltage during the first 12 hours, and 13-14% in the first 24hrs. Brand names did marginally better. Hybrids (GP ReCyko) were up to their marketing in this respect, barely 0,5% voltage drop during that time.

It's been an interesting exercise. Most likely I'll get some Sanyos or other brand name, hi-capacity NiMHs and use those as my primary batteries with the Fenix. Hybrids will stay in the bag for backup, as their self-discharge rate is low enough to guarantee they're actually up to the task when needed. I don't mind the shorter burn time with them, they're only there to get me home. Old NiMHs will go in my backup light, rear leds and such.
