I just did some recharging today after seeing this thread. It had been several months (6+ probably). I was surprised to find that my LiION's had held their charge slightly better than my Eneloop NiMH's. I would have expected just the opposite.

I thought Eneloop's claim to fame was a longer shelf life (at the expense of total capacity) when compared to non-Eneloop NiMH's. I don't have any non-Eneloop NiMH's to compare to, but the LiION (AW brand protected 14500's specifically) held charge better than the Eneloops.
