BU-402: What Is C-rate?

Losses at fast discharges reduce the discharge time and these losses also affect charge times. A C-rate of 1C is also known as a one-hour discharge; 0.5C or C/2 is a two-hour discharge and 0.2C or C/5 is a 5-hour discharge. Some high-performance batteries can be charged and discharged above 1C with moderate stress.
