yes there is.Best if used By 2002, but they sure could a fooled me cause it's 2012 and they work just fine. I have oodles of them. they were part of our emergency Gear at work, but since they were outdated, by law they had to go. I tell you what, if you are dissatisfied i will ship you replacements. just can't use them on any heavy draining type of equipment. but for remotes and small flashlights, they are fine
