The battery energy calculator allows you to calculate the battery energy of a single cell or a battery pack. You need to enter the battery cell capacity, voltage, number of cells and choose the desired unit of measurement. The default unit of measurement for energy is Joule.
In the ideal/theoretical case, the time would be t = capacity/current. If the capacity is given in amp-hours and current in amps, time will be in hours (charging or discharging). For example, 100 Ah battery delivering 1A, would last 100 hours. Or if delivering 100A, it would last 1 hour.
