The battery that we have has a minimum C rate of 0.2C. So, a battery with a lower C rate is needed in this application. You can easily calculate the maximum charge/discharge current of a battery from its C rating. Just multiply the battery capacity with the C-rating mentioned on the battery back.
The discharge current represents the rate at which the battery is discharged. To calculate it, use the formula: Discharge Current (I) = Rated Capacity (C) / Discharge Time (t) For example, if a battery has a rated capacity of 100 Ah and will be discharged over 10 hours, the discharge current would be: I = 100 Ah / 10 hours = 10 A
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.
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.
Maximum Continuous Discharge Current – The maximum current at which the battery can be discharged continuously. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
C rate (max) = Charging or Discharging Current(max) / Nominal Capacity Example 1: The device draws a steady current of 1A. The capacity and maximum C rate of the battery are 2500 mAH and 2C, respectively. Let’s calculate the discharge C rate for this application: This is within permissible limits.
