For a given capacity, C-rate is a measure that indicate at what current a battery is charged and discharged to reach its defined capacity. A 1C (or C/1) charge loads a battery that is rated at, say, 1000 Ah at 1000 A during one hour, so at the end of the hour the battery reach a capacity of 1000 Ah; a 1C (or C/1) discharge drains the battery at that same rate.
