Nickel–Cadmium Batteries
Nickel–cadmium batteries, unlike some other battery systems, show very stable voltage of 1.2 V for the majority of the discharge process up to the point where there is a "knee" in the curve and a sharp drop at the end of discharge (Fig. 4.6). The point when the battery reaches 0.9 V is considered the end of discharge and full capacity.

Compared to other batteries, NiCd batteries have a moderate self-discharge rate (i.e. the rate at which the battery loses its charge when not in use). If a NiCd battery is not fully discharged and recharged during use, the next time it is discharged, it will not be able to discharge the full charge.
