Battery capacity calculator — other battery parameters FAQs If you want to convert between amp-hours and watt-hours or find the C-rate of a battery, give this battery capacity calculator a try. It is a handy tool that helps you understand how much energy is stored in the battery that your smartphone or a drone runs on.
The rated capacity of a battery often expressed as the product of 20 hours multiplied by the current that a fresh battery can supply for20 hours at room temperature. The real (not rated) capacity or any battery depends on the load, that is, on the current, it supplies to the load or its discharge rate.
Suppose a battery has an internal resistance of 0.3 ohms, and the battery voltage is 0.9V. Calculate the current flowing through the battery. Given: V b (V) = 0.9V, R b (Ω) = 0.3 Ω. Battery voltage, V b (V) = I b (A) * R b (Ω)
Enter the values of current, I b (A) and internal resistance, R b (Ω) to determine the value of battery voltage, V b (V). Battery Voltage is a fundamental parameter in electrical engineering and electronics, indicating the potential difference across a battery’s terminals.
Battery Capacity in mAh = (Battery life in hours x Load Current in Amp) / 0.7 Battery Capacity = (Hours x Amp) / Run Time % Where; Note: In an ideal case, the battery capacity formula would be; Battery Capacity = Battery Life in Hours x Battery Amp Related Posts: Enter value, And click on calculate.
Therefore, the charge in the battery is defined from Q = I · t from the known capacity in Ah, which is the current a battery can provide for 3600 seconds: Cbat is the rated capacity of the battery in amperes-hours. Ns is the number of batteries in one or several series sets.
