What's Battery Memory Effect?

Memory Effect

Also known as battery effect, lazy battery effect, crazy battery syndrome 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.

How To Fix The Memory Effect

The simplest way to remedy the memory effect is to replace your nickel cadmium battery with a non nickel cadmium battery. You can find replacements on Amazon or at Limewit. You can also do a full discharge, from 100% to 0%, to your nickel cadmium battery multiple times to erase the memory effect.

NOTELimewit batteries do not suffer from any memory effect symptoms or side-effects since none of our batteries are nickel cadmium based.
