Been having problems with my green laser pointer stopping working. Replace batteries, fixed. Few minutes later, dead. Replace batteries, fixed. Few minutes later ... yawn. Put in pocket, and it was working again. I suspect that the batteries stop working in the cold, and get better when warm.

(The laser itself has such low thermal inertia it is a bit hard to tell if its the laser or the batteries).

Anyone seen something similar? Any recommendations on good AAA batteries for cold weather? (The laser lives screwed to the side of the scope as an all-sky finder/pointer, so I can't just keep it toasty warm in my pocket.)
