A few people have reported that the new 123 tailcap would not work with SureFire batteries.
I did some more playing before I sent mine back and found that it was more than just the battery brand that mattered.
Mine would work with brand new Toshibas and Sanyos but not with some used Toshibas and Sanyos.
Used Enerizers also wouldn't work.
It looks like a lot of the 123 batteries get dented on the negative terminal as soon as they're installed in something.
This dent looks like the determining factor in whether it will work in the new Arc tailcap.
Used batteries from my old-style Arcs where the nipple left a good sized dent definitely wouldn't work in my new Arcs.
Used Energizers out of my E2 and E2e also wouldn't work because they too had good sized dents.
The only used batteries that I could get to work in this new style Arc were those that came out of lights with springs in the ends.
Used Sanyos from my Scorpion and used Toshibas from my Arc clickie both worked.
