The battery discharge rate is the amount of current that a battery can provide in a given time. It is usually expressed in amperes (A) or milliamperes (mA). The higher the discharge rate, the more power the battery can provide. To calculate the battery discharge rate, you need to know the capacity of the battery and the voltage.
