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:
“Beauty sat bathing by a spring,
Where fairest shades did hide her;
The winds blew calm, the birds did sing,
The cool streams ran beside her.
My wanton thoughts enticed mine eye
To see what was forbidden:
But better memory said Fie;
So vain desire was chidden—”
—Anthony Munday (1553–1633)
“The second [of Zeno’s arguments about motion] is the one called “Achilles.” This is to the effect that the slowest as it runs will never be caught by the quickest. For the pursuer must first reach the point from which the pursued departed, so that the slower must always be some distance in front.”
—Zeno Of Elea (c. 490–430 B.C.)
