Nicad

Trademarked name for a Nickel-Cadmium battery owned by SAFT America Inc. Nicad is a rechargeable battery, made mostly of nickel and cadmium. A primary problem with nickel-cadmium batteries was that they needed to be completely drained of power before they could be recharged.

Known as a memory loss or memory effect, if the battery was not completely drained, once the battery reaches its last low level, the battery would go dead, assuming that no power was left.
