5 of 5 Worked perfectly for Sub-Zero backpacking! March 18, 2023
Reviewer: Andrew Burnett from Newfoundland, Canada  
I bought these for winter camping and backpacking in Eastern Canada and they've performed perfectly in a headlamp, well below freezing. I'm excited  to pair them with a HU60 for hiking in the coldest temperatures.

5 of 5 Works great January 9, 2023
Reviewer: Chayton McCaslin from Fairbanks, Alaska  
I’m up in Alaska where it’s typically really cold and dark and most LI batteries lose a bit of life from the cold but these have worked great so far for me wouldn’t really suggest these if your not regularly below -10 though
