Anyone else have problems with batterylife using their M-80XD? It is has been in the single digits at night and teens during day for temperatures. I have been using Rayovac Alkaline batteries which I know have poor batterylife in cold temperatures. Will Lithiums work better in these cameras? I have always used Lithiums in my Reconyx but in the Reconyx there is a setting for lithium batteries. I am looking for any and all recommendations.

Aside from the batterylife the 4 M-80XDs I have take great pictures and the flash range is better then anything I have seen. But without batteries everything good is voided.
