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
