Question

What Is Discharge Rate Of Battery?

Answer 1

1. A common way of specifying the battery capacity is to mention the battery capacity as a function of the time taken to fully discharge the battery.
2. By this method, the battery capacity is notated as $Cx=Z$ where $x$ is the time taken (in hours) to fully discharge the battery and $Z$ is the battery capacity when the battery is discharged in $x$ hours. For example, $C10=Z$ means that the battery capacity is $Z$ when the battery is discharged in 10 hours.
3. The discharge rate is obtained by dividing the battery capacity by the time taken to discharge the battery. For example, a battery of 500 Ah capacity that is fully discharged in 20 hours has a discharge rate of $\frac{500Ah}{20h}=25A$.
4. Thus, the discharge rate of a battery is the battery capacity divided by the time it takes to completely discharge the battery.
