            All batteries have a shelf life, by the way.  So do we humans.  And these batteries  do have to recharged, too, in order for we humans to get the benefit. The general shelf life is usually around 8 years, but does vary all over the place, too. In all cases, do label the batteries the best you can if they are not otherwise labeled.
