For example, a battery with a higher Ah rating will be able to power a device for a longer duration compared to a battery with a lower Ah rating. To calculate the total energy capacity of a battery in Ah, you need to multiply the current (in amperes) by the time (in hours) the battery can sustain that current.
Therefore, the battery of capacity should include the charging/discharging rate. A common way of specifying battery capacity is to provide the battery capacity as a function of the time in which it takes to fully discharge the battery (note that in practice the battery often cannot be fully discharged). Temperature. The temperature of a battery ...
