Memory effect, also known as battery effect, lazy battery effect or battery memory, is an effect observed in nickel cadmium rechargeable batteries that causes them to hold less charge. It describes one very specific situation in which certain NiCd batteries gradually lose their maximum energy capacity if they are repeatedly recharged after being only partially discharged. The battery appears to "remember" the smaller capacity. The source of the effect is changes in the characteristics of the underused active materials of the cell. The term is commonly misapplied to almost any case in which a battery appears to hold less charge than was expected. These cases are more likely due to battery age and use, leading to irreversible changes in the cells due to internal short-circuits, loss of electrolyte, or reversal of cells.

Famous quotes containing the words memory and/or effect:
“Always get rid of theory private object in this way: assume that it constantly changes, but that you do not notice the change because your memory constantly deceives you.”
—Ludwig Wittgenstein (1889–1951)
“The use of symbols has a certain power of emancipation and exhilaration for all men. We seem to be touched by a wand, which makes us dance and run about happily, like children. We are like persons who come out of a cave or cellar into the open air. This is the effect on us of tropes, fables, oracles, and all poetic forms. Poets are thus liberating gods.”
—Ralph Waldo Emerson (1803–1882)
