I bought these hoping they would be used in TV remotes and other devices and last longer. Not so. They don't even last half the life of a regular Duracell copper plate. I don't know who is giving the rave reviews, but there are numerous 1-3 reviews on another review site, all with the same low life issue at this particular Optimum. Many reviews have battery leaks and other defects right out of the box.
