I purchased two 4 packs of the TI 3V AA size Lithium primaries from Battery Junction to use as back-ups for my 14500 lights. I like single AA lights and always EDC one that can use either a primary or 14500 LI, I figured I could keep a few of these batteries in my car and get (some of) the best of both worlds.
I tried the new batteries in a couple of lights tonight and am confused by my findings, I hope there's someone here that can clear this up for me. In one light, the TI batteries seem to perform similar to a 14500, in another more like a AA??? I did some very quick and dirty comparisons:
