Why do most people refer to Nominal voltage instead of Fully charged voltage?

Nominal voltage is the standard voltage rating given to a battery or other electrical component. It is an approximate value that is used to indicate the voltage range over which the component operates safely and effectively. The nominal voltage is generally lower than the fully charged voltage because it reflects the average voltage range that a component will operate in during its lifetime.

Using the fully charged voltage instead of the nominal voltage can lead to several issues. Firstly, the fully charged voltage is not a constant value, and it can vary depending on the temperature, charge level, and other factors. Secondly, using the fully charged voltage as the standard voltage can result in overloading the components, which can damage them or reduce their lifespan.

Another reason for using nominal voltage instead of fully charged voltage is that it provides a standard reference point for comparing different components. For example, if two batteries have a nominal voltage of 12V, then they can be compared easily based on their performance and other specifications. If one battery has a fully charged voltage of 13V and the other has a fully charged voltage of 14V, then it becomes harder to compare them directly.

Overall, using nominal voltage as the standard voltage rating provides a safe and reliable way to operate electrical components, and it allows for easy comparison between different components.
