Most of my battery powered equipment had warnings about temperature ranges, I would expect the same for the newer Lithium ION batteries, I have a Craftsman tool that uses these, and it sat for 3 years in the cabinet in the garage and I went to use it and it still was charged. I think I may do a search on this subject just to see what comes up.
