What is the nominal output voltage of a fully charged nickel-cadmium battery?

The nominal output voltage of a fully charged nickel-cadmium (NiCd) battery is typically around 1.2 volts. This is a standard value for nickel-cadmium batteries, which are used in a variety of applications, including some consumer electronics and power tools. The voltage is considered nominal because it reflects the average output under standard conditions rather than the precise voltage delivered at all discharge currents or states of charge.

While options such as 1.5 volts and 1.0 volts might reflect voltages for other types of batteries—like alkaline batteries that have a higher output voltage, or certain other battery chemistries whose nominal voltages may differ—the characteristic output voltage for fully charged NiCd cells is consistently identified as 1.2 volts.

Thus, the selection of 1.2 volts aligns with established specifications for nickel-cadmium batteries, making it the correct choice in this context.
