Understanding Ah: The Unit of Electric Charge for Batteries and Energy Storage

Ampere-minute (Ah) is a unit of electric charge, defined as the product of the current in amperes and the time in minutes. It is often used to express the capacity of a battery or other energy storage device.

For example, if a battery has a capacity of 20 Ah, it means that it can supply a current of 20 amperes for one minute, or a current of 10 amperes for two minutes, and so on.

Ah is often used in the context of batteries and other energy storage devices, as well as in the specification of electrical systems and equipment. It is a useful unit of measurement because it takes into account both the amount of current and the duration of the current flow, which can be important factors in determining the performance of an electrical system or device.
