Discharge Current vs Battery Capacity
Battery Discharge Rate
Formulas
I_discharge = Capacity / Time
C-rate = 1 / Time(hours)
Energy = Capacity x Voltage
A 1C rate discharges the battery in 1 hour. 0.5C takes 2 hours. 2C takes 30 minutes.
Example Calculation
5000 mAh battery to be discharged in 10 hours.
- 01Current = 5000 / 10 = 500 mA
- 02C-rate = 1 / 10 = 0.1C
- 03Energy = 5000 x 3.7 / 1000 = 18.5 Wh
