They last longer!!!!,

This review is from: Duracell Hearing Aid Batteries Size 312 pack 60 batteries (Health and Beauty)
I went with a cheaper battery last time, saving small change on each, but I was constantly changing batteries. These are lasting much longer, so I won't have to fool with my hearing aids all the time, and the longer they last the cheaper they are! Win, win.
