we like energizer batteries, they are dependable and have a long shelf life so we can buy the big boxes, the last battery is as long lasting as the first battery was. we have a box of energizer batteries in our cabin, even after 2 years in the heat of summer to the sub zero of winter the energizer batteries still are as good as new, they have never leaked like other batteries will when left for a much shorter time
2 days or more, we have left a flashlight w/ 2 D cell energizer batteries turned on in our cabin for 2 days, after being stored in the flashlight for 1 year.
