You wouldn’t want to buy premium lithium batteries to power your TV remote, but they typically do work better and last longer in high-drain devices (such as bright LED flashlights). In addition to cold weather performance, CR123/CR123A and Energizer Ultimate Lithium batteries have longer shelf lives and higher charge capacities than alkaline batteries. Beyond that you are likely to see greatly diminished performance. temperature chart in Energizer’s L91 datasheet, both battery types are practically effective at temperatures down to about -20☌, or -4☏. Energizer L91 Lithium Battery Capacity and Temperature Curveīased on recommendations stated in Panasonic’s datasheet and this capacity vs. Panasonic’s CR123A lithium batteries ( PDF) have an operating temperature range of -40° to + 70☌ (-40° to 158☏), while Energizer’s Ultimate Lithium L91 AA batteries ( PDF) have a similar operating temperature range of -40° to 60☌ (-40° to 140☏). Lithium batteries, on the other hand, perform quite well when it’s cold out. Any colder than that and you can probably expect to see greatly reduced performance in medium and high-drain flashlights and devices.

Rechargeable batteries tend to perform poorly in cold temperatures as well. I typically use Sanyo Eneloop NiMH batteries in my AA and AAA-sized flashlights, but these batteries aren’t any better than alkalines when temperatures drop near freezing.Īccording to Sanyo’s datasheet ( PDF), basic AA Eneloops are only rated down to 0☌/32☏. In some cases, cold temperatures can cause alkaline batteries to burst and leak.
