Discharge Time (minutes)

Note: [It] was previously expressed as [C]. [It] is an IEC standard expression for the amount of charge or discharge current and is expressed as: It(A) = Cn (Ah)/1h.

•[It] is the reference test current in ampres•[Cn] is the rated capacity of the cell or battery in Ampere-hours.n = the time base [hours] for which the rated capacity is declared
