Now, to calculate battery watt hours, we will need only 2 key metrics: Amp hours (Ah). This is your 100Ah battery, for example. Voltage (V). Most batteries have a 12V voltage. Some bigger batteries can have 24V or even 48V voltage. Fortunately, all batteries will have both Ah capacity and voltage prescribed on the battery itself (or the label).
Quick example of why knowing watt-hours (Wh) is useful: A 100Ah 12V lithium battery has a 1,200 Wh capacity. That means that it can run: A 1,200 watt appliance for 1 hour. A 1 watt appliance for 1,200 hours. A 100 watt appliance for 12 hours, and so on. You get the point. Inner structure of a 100Ah lithium battery.
Formula to Calculate Lithium Battery Watt-hour Rating If your lithium battery does not have the Watt-hour rating clearly marked on it and the Wh rating is not included on a product documentation you can do some quick math to determine the Watt-hour rating yourself, using some other information commonly found on the battery. You will need to know:
To calculate battery watt hours, you simply multiply the battery''s voltage by its ampere-hour rating. For example, if a battery has a voltage of 12 volts and an ampere-hour rating of 10 Ah, the calculation would be 12 volts multiplied by 10 Ah, resulting in 120 watt-hours.
