Explanation
The ability to output energy per unit time. It is numerically equal to the product of output current and output voltage V; The smaller the internal resistance of the unit internal resistance of the battery, the higher the output power. Generally, the internal resistance of the internal resistance of the battery should be less than that of the electrical appliance, otherwise the power consumed by the battery itself will be greater than that consumed by the electrical appliance, which is uneconomical and may damage the battery. Under rated voltage, the output power of the battery increases with the increase of electrode surface area and operating temperature, and vice versa.
