What is the battery“Memory effect”? How does it mean?

Memory effect, which is often know as lazy battery effect, battery effect or battery memory, is an effect happen in the Ni-CD rechargeable batteries. This effect will cause the Ni-CD Batteries to hold less charge. It describes one very specific situation in which certain Ni-CD batteries lose their maximum energy capacity little by little if they are repeatedly recharged after not being fully charged.

For example, if a 100% charged Ni-CD battery is used to 20% but not being fully charged, let us say it, charged to 80%, then the battery will “remember” 80% is a fully charged circle, so, in this case, the battery carry less capacity than before.
