Watt Hours To Amp Hours Conversion (Wh To Ah)
If you have a 0.5A load, multiplying 9V by 0.5A gives you 4.5 watts. If you have a 1A load, multiplying 9V by 1A gives you 9 watts. Technically speaking, you cannot identify the watts unless you know the amperage. To calculate the watts, you have to multiply the voltage by the amps. 9V batteries do not have the wattage rating on their label.
