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).
Battery capacity calculator — other battery parameters FAQs If you want to convert between amp-hours and watt-hours or find the C-rate of a battery, give this battery capacity calculator a try. It is a handy tool that helps you understand how much energy is stored in the battery that your smartphone or a drone runs on.
Energy is equal to amp-hours multiplied by volts. Converting battery amp hours to watt-hours will give an idea of how much actual energy your battery can store or deliver. For example, A 36v 12.8ah battery can store or deliver more energy than a 12v 30ah battery.
Calculate the total voltage by adding the voltages of batteries in series. Calculate the total amp-hour capacity by summing amp-hours in parallel. Multiply total voltage and amp-hour capacity for total watt-hours. Example: A 200Wh battery running a 50W device has a run time of 4 hours (200 ÷ 50).
To measure a battery's capacity, use the following methods: Measure the time T it takes to discharge the battery to a certain voltage. Calculate the capacity in amp-hours: Q = I×T. Or: Calculate the capacity in watt-hours: Q = P×T. What is the C rating of a battery? The C rating determines the rate at which the battery discharges.
