** For reference only.  
Battery performance and cycle life are strongly affected by how they  
are used. In order to maximize battery safety, please consult Panasonic  
when determining charge / discharge specs, warning label contents  
and unit design.  
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
