The battery discharge rate is the amount of current that a battery can provide in a given time. It is usually expressed in amperes (A) or milliamperes (mA). The higher the discharge rate, the more power the battery can provide. To calculate the battery discharge rate, you need to know the capacity of the battery and the voltage.
The faster a battery can discharge, the higher its discharge rate. To calculate a battery’s discharge rate, simply divide the battery’s capacity (measured in amp-hours) by its discharge time (measured in hours). For example, if a battery has a capacity of 3 amp-hours and can be discharged in 1 hour, its discharge rate would be 3 amps.
There is no generic answer to this. You read the battery datasheet. Either it will tell you the max discharge current, or it will tell you the capacity at a particular discharge rate, probably in the form C/20 where C means the capacity. You know the current you need : 4.61A.
From the above equation, the variation of discharge time is dependent on the discharge current. The battery capacity also greatly depends on the discharge current. This means that the capacity for the one hour rate is 60% less of the 20 hour rate. Evidently, increasing discharge current causes a decrease in the apparent Ah capacity.
1 - Enter the battery capacity and select the unit type. For example, If you have a 50 amp hour battery, enter 50 and select Ah. 2 - Enter the battery c-rating number (mentioned by the manufacturer on the specs sheet of your battery). Enter "Calculate" button to find out the results. where to find battery c rate?
To calculate the C-rate of a battery, divide the current (in amps) by the capacity (in amp-hours). For example, if a battery has a capacity of 1000 mAh and can deliver a current of 2000 mA, then its C-rate would be 2C.
