The battery capacity is the current capacity of the battery and is expressed in Ampere-hours, abbreviated Ah. Chemical Capacity – full storage capacity of the chemistry when measured from full to empty or empty to full. This is normally defined at a given C-rate and maximum and minimum voltages.
The battery capacity corresponds to the quantity of the electric charge which can be accumulated during the charge, stored during the open circuit stay, and released during the discharge in a reversible manner.

Under well defined conditions this is often referred to as the Rated Capacity as the battery capacity is likely to be different under different temperature, discharge rates and prior use. An alternative unit of electrical charge. Product of the current strength (measured in amperes) and the duration (in hours) of the current.
In summary, the specific capacity related to the mass of the active material is a suitable indicator in the context of pure material characterization, e.g., rate capability testing. However, excellent performance at the material level does not automatically lead to favorable battery performance.
The energy stored in a battery, called the battery capacity, is measured in either watt-hours (Wh), kilowatt-hours (kWh), or ampere-hours (Ahr). The most common measure of battery capacity is Ah, defined as the number of hours for which a battery can provide a current equal to the discharge rate at the nominal voltage of the battery.
The ‘theoretical capacity’ of a battery is often calculated using Faraday's law of electrolysis; but the ‘practical capacity’ is always less. The practical capacity is influenced by many factors, including the discharge rate, the cutoff voltage, the temperature, and the sample history.
