Current is expressed in Amps (A). It quantifies how many electrons are flowing per second. The capacity of a battery defines how much total energy is stored in each battery. The power output of a battery is how much energy a battery can give at a given time. This is a very important factor as it defines what you should use the battery for.
How is battery capacity measured?
Battery capacity is measured in ampere-hours (Ah) or milliampere-hours (mAh). Battery capacity indicates the amount of electric charge a battery can store. Ampere-hours represent the flow of current over time. For example, a battery rated at 1 Ah can deliver 1 ampere of current for one hour.
What is the difference between battery capacity and discharge time?
Battery capacity (C)= Constant Current of Discharge Battery (I) X Discharge Time (T) The capacity of a battery is the amount of electricity it can store and it is measured in Ampere-hours (Ah) and Watt-hours (Wh). The Amperes (A) indicate a steady current of a battery that stays constant over time.
What is a battery's capacity?
A battery's capacity is the amount of electric charge it can deliver at a voltage that does not drop below the specified terminal voltage. The more electrode material contained in the cell the greater its capacity. A small cell has less capacity than a larger cell with the same chemistry, although they develop the same open-circuit voltage.
