What Is the Output Power of Battery?

The output power of a battery refers to the ability to output energy per unit time. It is calculated based on the discharge current I and the discharge voltage, P=U*I, the unit is watts.

The smaller the internal resistance of the battery, the higher the output power. The internal resistance of the battery should be smaller than the internal resistance of the electrical appliance. Otherwise, the battery itself consumes more power than the electrical appliance, which is uneconomical and may damage the battery.
