The formula for determining the energy capacity of a lithium battery is: Energy Capacity (Wh) = Voltage (V) x Amp-Hours (Ah) For example, if a lithium battery has a voltage of 11.1V and an amp-hour rating of 3,500mAh, its energy capacity would be: Energy Capacity (Wh) = 11.1V x 3.5Ah = 38.85Wh.
In many previous studies, only battery energy capacity is considered to determine the battery size, especially for lead-acid batteries, where the power capacity and energy capacity are highly coupled [42].
Q = amount of charge stored when the whole battery voltage appears across the capacitor. V= voltage on the capacitor proportional to the charge. Then, energy stored in the battery = QV. Half of that energy is dissipated in heat in the resistance of the charging pathway, and only QV/2 is finally stored on the capacitor.

Practical Examples: Illuminating the Battery Capacity Formula. Example 1: If a 12V battery discharges at 5A over a period of 2 hours, its capacity is calculated as follows: Capacity = 12V x 5A x 2h = 120Ah. Example 2: For a 6V battery delivering a 3A current for 4 hours, the capacity would be: Capacity = 6V x 3A x 4h = 72Ah.
