For example, if a battery has a capacity of 3000 mAh, then its Ah rating would be 3 Ah. Finally, to calculate the capacity of a battery in amp hours, you can use the current flowing in the battery and the amount of time that the battery can provide power at that current and multiply both values: amp hours = current × time.
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.
Other units include milliamp-hours (mAh) and watt-hours (Wh), which are used for smaller or larger capacity batteries, respectively. Calculating the capacity of a battery is an essential step in determining its performance and suitability for specific applications.
The requirement is to compute the capacity of the battery in order to calculate the capacity degradation. The input which can be acquired are current, voltage, relative time, battery level (in terms of percentage). Capacity = Integral of Current over time. (of discharge cycle)
The capacity of a battery is the amount of energy that it can store. A battery's capacity is expressed in amp hours (Ah), which is a measure of electrical current over time. One amp hour equals one amp of current flowing for one hour. The higher the Ah, the longer the battery will last.
So to establish the required capacitance for a given battery use. In this case, discharge to 0.54V would increase capacitance needed only by about 5%. For an endpoint voltage of 1V you have remaining energy of 1V^2 / 2.7V^2 =~ 14% energy remaining.
