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:
“What has kept the world safe from the bomb since 1945 has not been deterrence, in the sense of fear of specific weapons, so much as it’s been memory. The memory of what happened at Hiroshima.”
—John Hersey (b. 1914)
“I guess what I’ve really discovered is the humanizing effect of children in my life—stretching me, humbling me. Maybe my thighs aren’t as thin as they used to be. Maybe my getaways aren’t as glamorous. Still I like the woman that motherhood has helped me to become.”
—Susan Lapinski (20th century)
