Lithium or Alkaline in winter ourdoor temp sensor?

I have an indoor/outdoor temperature thingy. For the outside temperature sensor, during real winter (below freezing for a few months), are alkaline AA cells ok to use or should I install lithium AA cells? The outdoor sensor unit runs on 2 AA.

Describes the Lithium Batteries available from Energizer. Lithium Battery technology is available in Battery Sizes AA, AAA and 9v.
 

How do i get a real engineering spec sheet for 9V advanced lithium battery.

I am working on a product design that could use this battery. I cant tell without a product spec sheet. Also, is there an industrial version of this that i should consider for my design.
My product choices are primarily driven by: industrial products
have you looked on data.energizer.com for info? or do you need more details? i'm guessing "more details" would be proprietary, so if the stuff from data.energizer.com is not enough, you may be stuck.

What is the milliamp-hour rating of AA cells?

I suggest load currents of 100 mA, and 1000mA. It would be great if you could provide comparison figures for Energizer alkaline cells, too.
My product choices are primarily driven by: Need batteries for 2-way radio.
if you go to data.energizer.com you should be able to pull up datasheets on a wide range of batteries. if memory serves, at room temp and low current rates, the lithium is only slightly higher capacity than alkaline - like around 10% to 15%. but at subfreezing temps and/or high current drain rates, the lithiums don't lose capacity anywhere near as quickly.
