Yeah. Alkalines don't like the cold. I learned that with my Streamlight Jr luxeon. The boost circuit won't even come on with cold alkalines. It stays in my car so it gets cold.
I put NiMH in it and it works great though. Lithium AA would work too but they are $$$
Not sure at what temp they stop performing well or quit alltogether... I guess they can freeze too since they have liquid in them...

It depends on the current draw. I would guess that much below 40F or so they're really limited.
I have an outside temp sensor that transmits the temp and humidity. A set of 2 AAA's alkies runs about 2 years. It's worked fine down to -10 and lower.
On the other hand, I wouldn't expect them to give much light if you had, say, a PT Tec 40 or other light which would drain them dry in 2-4 hours.
There must be a temp current curve somewhere that shows what the current drop (or equivalent increase in internal resistance is) by temp......

Sure there is:
Energizer Temperature Effects.
OTOH, it seems that warming 'em up brings 'em back to life....

I haven't tried it lately, but I think the batteries will come back to life if you bring them inside for a while. It's been down to zero with the wind chill and I was thinking about leaving some lights and batteries outside for a while to see how much of a difference I notice.
