I have no idea about cell cameras but my regular trail cams get 10 months out of alkaline batteries. They'll take thousands of pictures in that time. Alkaline cost is about .75 each on sale. That's about 7 bucks a year per camera. That's so cheap I don't consider anything else.
Also, my cameras take pictures without regard to temperature. Central Illinois so we rarely go below -10.
