This gives the power in terms of only the current and the resistance. Thus, by combining Ohm''s law with the equation P = I V P = I V for electric power, we obtain two more expressions for power: one in terms of voltage and resistance and one in terms of current and resistance. Note that only resistance (not capacitance or anything else), current, and voltage enter into the …

Learn the formula for electrical power. Power in an electrical circuit depends on two quantities: current and voltage. A higher current (faster electrical charge) transfers electrical energy more quickly, increasing power. A higher voltage means each unit of charge transfers more energy as it moves, also increasing power.

Lower the discharge rate higher the capacity. As the discharge rate ( Load) increases the battery capacity decereases. This is to say if you dischage in low current the battery will give you more capacity or longer discharge . For charging calculate the Ah discharged plus 20% of the Ah discharged if its a gel battery.
To calculate the Watt-hours (Wh) of a battery, follow these steps: Find the battery''s voltage (V) and amp-hours (Ah) from its specifications. For example, a 12V50 battery has 12 V voltage and 50 amp-hours capacity. Multiply the battery''s voltage by its amp-hours to get the battery''s capacity in Watt-hours: capacity (in Wh) = voltage × amp-hours
Example: In our example, the calculation would be as follows: Amp Hours = 2.5 A x 5 h = 12.5 Ah Therefore, the battery should have a capacity of at least 12.5 amp hours to power the device for 5 hours.
