batteries. A C-rate is a measure of the rate at which a battery is discharged relative to its maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps.
Battery capacity measurement typically involves discharging a fully charged battery at a constant current until it reaches a specific cutoff voltage. The current and time are recorded during the discharge process. The product of these two values gives the capacity in ampere-hours (Ah) or milliampere-hours (mAh). For instance, if a battery is discharged at 500 milliamps and it lasts
Battery capacity is a fundamental concept in the world of portable electronics and energy storage.
