19、f the cell or battery in ampere hours (Ah). Objections have been raised that to divide or multiply C results in a fraction or multiple of Ah and it is therefore mathematically incorrect to express current (amperes (A) in this way.

21、s. It proposes a mathematically correct method of current designation which shall be used in future secondary cell and battery standards. 2 Method of designation The reference test current as specified in the various test methods detailed in a standard shall be expressed as: C,Ah lh /,A=- where i, i

22、s the reference test current, in amperes; C, is the rated capacity of the cell or battery as declared by the manufacturer, in ampere-hours; n is the time base (hours) for which the rated capacity is declared. All charge and discharge currents shall then be expressed as fractions or multiples of 1,.

23、The value of n used in the standard determines only the fraction or multiple of /, used fdr the various specified purposes in that standard. For example, if n = 5, then the discharge current used to verify the rated capacity shall be 0,2 /,A. If n = 1, the discharge current used to verify the rated

24、capacity shall be 1 ,O /,A. Note that the value of n used in the standard has no effect on the value of value of /, will always be equal to the numerical value of C, regardless of the value of n.
