Understanding Ampere-Hour (Ah) - The Unit of Measure for Electrical Charge

Ampere-hour (Ah) is a unit of measure for electrical charge, and it represents the amount of energy that a battery can store. It is calculated by multiplying the current in amperes (A) by the time in hours (h) during which the current flows.

For example, if a battery has a capacity of 2000mAh, it means that it can supply a current of 2 amperes for one hour, or a current of 1 ampere for two hours, or any other combination of current and time that adds up to 2000 milliampere-hours.

The unit of ampere-hour is often abbreviated as "mAh" or simply "Ah", and it is commonly used to describe the battery capacity of portable electronic devices such as smartphones, tablets, and laptops.
