When speaking of a battery or battery pack we use the word nominal (in name only) to refer to the voltage, "a nominal 12 volt battery", or, "a nominal 36 volt battery pack."

The reason for this is because a 12 volt battery is rarely ever 12.00 volts. Most batteries have a working range of 11 volts as a low and 14 volts as a peak. If a battery goes below or above these numbers, permanent damage will occur.
