WebWhere the current is measured in A, the voltage is measured in V, and time in hours. So, energy = A * V * hr = Ahr *V Wh gives a more accurate capacity of batteries because it includes the voltage and the ampere-hour. In as much as amp-hour determines how much charge is in a battery, you can’t compare batteries by just using it. Web28 mei 2024 · To get the capacity as a percentage, you can simply measure the voltage and subtract one point one. Then, multiply by 200 to get the capacity percentage. For example, if a cell has a voltage of 1.58 volts, you would subtract 1.1 volts to get 0.48 volts. Then, you would multiply by 200 to get 96% capacity.
