How long is 1 mAH?

1 mAh (milliampere-hour) is a unit of electric charge that represents the amount of current a battery can provide over one hour. Specifically, it indicates that a battery can deliver a current of one milliampere (0.001 amperes) for one hour before being depleted. This measure is commonly used to describe the capacity of small batteries, such as those in watches or hearing aids.
