Explanation
The amount of electricity that a battery can release under certain discharge conditions, that is, the integral value of the discharge current over time when the battery is discharged to the rated termination voltage, usually measured in amperes per hour (A/h) or milliamperes per hour (mA/h). According to conditions, cell capacity can be divided into theoretical capacity, actual capacity and rated capacity. The theoretical capacity of the battery can be calculated according to the electrochemical equivalent of the electrode active substance and its content in the battery. The actual capacity of the battery refers to the capacity actually released under certain conditions during the test or application process. The actual capacity is always less than the theoretical capacity. The rated capacity, also known as the nominal capacity, refers to the minimum capacity provided by the battery when it is discharged to the termination voltage under a specific condition specified during the design and production of the battery. The rated capacity is an important performance index in the battery product specifications.
