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.
