Note: 40 Typical Discharge Characteristics [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 Charge: 70mA(0.1It)x 15hrs., 20C.
