That makes me wonder about the cold temperature performance of my NiMH's. I
believe that Lithiums offer "almost-as-good-as-room-temp" performance when
they're chilled, while many others work much more inefficiently when
chilled. (I'm thinking of my own alkaline-vs-Li comparisons in LX's in the
cold.)  Does anyone know how NiMH's are ~supposed~ to perform in the cold?



They are supposed to perform pretty good. Better than NiCd or Alkaline and comparable to Li I believe.

NiMh are the popular choice for mountaineering use (head torches in the cold at altitude) and work well although for extreme situations a battery pack you can keep warm is better. I use NiMh for this purpose as I won't tolerate a non rechargeable battery for reliability reasons. If I charge the batteries before use I pretty well know how long they will last, I just don't have that confidence in disposables that have been on a shelf, stored in conditions I don't know and probably partly used on another occasion. There again in this application it's my life that is potentialy at stake - not just whether I can take another few pictures or not.

Rob.
