Discharge Current vs Battery Capacity
Formula
## 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.
Esempio Risolto
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
Domande Frequenti
What is C-rate?
C-rate expresses current relative to capacity. 1C means a current equal to the capacity rating, discharging in 1 hour.
Does C-rate affect battery life?
Yes. Higher C-rates cause more heat and stress, reducing cycle life. Most Li-ion cells prefer 0.5C or less.
What about depth of discharge?
Discharging only to 80% DOD significantly extends cycle life compared to full 100% DOD.
