The term “amp per hour” is often confused with “amp-hour,” but it’s important to clarify their meanings, as they refer to different concepts.
Amp-Hour (Ah): This is a unit of electric charge that represents the amount of electric current (in amperes) that can be delivered by a battery over a period of one hour. For example, if a battery has a capacity of 100 amp-hours, it means that it can theoretically deliver 100 amps for one hour, or 50 amps for two hours, or 25 amps for four hours, and so on, until the battery is depleted. The amp-hour rating is commonly used to specify the capacity of batteries.
Amp per Hour (A/h): This term is less standard and may not be widely recognized. If used, it could imply a rate of change of current over time, but it is not a standard unit of measurement in electrical engineering. For example, it might suggest how many amperes are being consumed or produced per hour, but this would typically not be a standard way to express electrical quantities.
In summary, “amp-hour” is a standard and widely used term for measuring battery capacity, while “amp per hour” is not a standard term and could be misleading. If you encounter “amp per hour,” it’s advisable to seek clarification on the intended meaning.
