My experience is lithium batteries really slow down electricity production in cold.
I’ve tested batteries for car flashlights, and found lithiums will die much faster than any other due to cold. Even after warming up they have less charge (and this use-case needs power now).
NiMH seems to tolerate cold much better for my use case.
I don’t store any batteries that I like outside - no battery tech likes extreme temps, some less than others.
More simplistically, pretty much everything dislikes temp swings or extremes, especially anything plastic. So that’s kind of my guide. If it’s plastic, I bring it in.
