Lithium AA batteries are the recommendation for cold-weather use. Alkaline batteries lose a significant portion of their capacity below freezing, which translates to shortened session time and reduced output. Lithium batteries maintain their rated capacity through cold temperatures and are worth the higher cost for fall and winter detecting. For machines with built-in rechargeable systems, check your manufacturer's cold-weather guidance — lithium-ion packs perform better than NiMH rechargeables in cold conditions in most cases.
