Understanding Charge-Discharge Curves of Li-ion Cells

C-Rate of discharge is a measure of the rate at which the battery is being discharged when compared to its rated capacity. A C/2 or 0.5C rate means that this particular discharge current will discharge the battery in 2 hours. For example, a 50Ah battery will discharge at 25A for 2 hours. A similar analogy applies to the C-rate of charge.
