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 NICKEL METAL HYDRIDE HANDBOOK AUGUST 2005 This information is generally descriptive only and is not intended to make or imply any representation, guarantee or warranty with respect to any cells and batteries.
