Best deal hands down! I say that because I use a lot of these for computers, watches, remotes and other electronics. I've tried many different brands, from other name brands (Energizer, Sony, Ray-O-Vac %26 Polaroid) to several generic brands to bulk brands , and Duracell outlasts them all! With the other brands I was changing them so often it was ridiculous! I'd started using the other brands in, my and my friend's, electronics and computers and I was changing them 2 to 3 times a year. When I went back to Duracell, I only had to change them once a year or longer! They really are the best, longest lasting batteries out there.
