These lithium batteries we had in February 2014 in Siberia and Lake Baikal in use at temperatures down to -35 degrees. A set of batteries held in a Nikon L320 camera approximately 1000 pictures in the highest resolution and about 1 hour filming in 720p resolution. No 5 star rating I give because we Energizer lithium batteries here have had the loose again managed 500 to 1000 images more in the same camera. The valuation of Energizer batteries can be read also here somewhere.
