How to calculate the power of the total potential of the battery
To calculate the run time of a 12V battery, you need to divide the watt-hour rating of the battery by the power consumption of the load. For example, if a 12V battery has a watt-hour rating of 100 Wh, and the load consumes 10 watts of power, the run time of the battery is around 10 hours. - Download [PDF]
