Gdetrailor,
My experience is that Alkaline batteries perform rather better than Li at low temperatures. It is anecdotal evidence.
Never tried the non rechargeable Lithium batteries as they are more expensive than standard alkaline dry cells.
However, according to THIS website, Energizer Lithiums ARE rated down to -40C (yes, negative 40 degrees Celsius).
My experience using alkaline drycells in my garage T stat pretty much proves to me that uses where temps are consistently below below 40F for several weeks isn't 100% reliable. They will of coarse come back to life once they warm up for a while..
According to THIS website, Alkalines work best at 60F-80F
According to THIS website, Alkalines lose 60% of their useful life if used at temps below zero F..
For the very reason of lack of extreme low temp performance of Alkaline drycells, I keep flash lights loaded with NIMH batteries in my vehicles with the downside of having to periodically remember to recharge them.
