I've had trouble with Energizer Lithiums. The problem lies not in the battery adapter, but with the batteries themselves! Check to see if one or two of those batteries are DOA, as one dead battery will sink the whole ship.
This really peeved me one day after I spent a bunch of money on those Energizer batteries, only to find out they don't work. I did some digging and came across some battery forums (there's a subculture for everything!) where people complained about some shipments of Energizers that were duds. I suspected that mine were part of it. Yours may be too.
I tested my AA adapter (I have 2, and they're both the cheapo knockoff Ebay from China variety) with regular gas station Duracell coppertops afterwards and got just over 200 shots with them. I also got two sets of Eneloops, and that is now what I use with my AA adapters, and they last somewhere in the neighborhood of 1000 shots. I don't buy Energizers anymore. Fool me once . . .
