The basic unit of battery capacity. One ampere-hour indicates that one ampere of electrical current can be drawn from a battery for one hour before depletion. Pulse generator batteries generally hold between 0.8 to 2.5 ampere-hours. Abbreviated A-h.
When the current is one ampere, the quantity of electricity that flows in one hour. Multiplying current in amperes by time of flow in hours equals ampere hours. In this case, batteries are often rated over an eight-hour period.
A measure of energy quantity, equal to amperes times hours. Also used to measure battery capacity.
