How did Peukert determine the capacity of a lead-acid battery?

In 1897 a German physicist, W. Peukert, determined that the capacity of a lead–acid battery depends on the discharge rate of the battery, saying that high discharge rates decrease the storage capacity by a predictable factor. \ [ { {C}_ {P}}= { {I}^ {k}}t\] Where: C is the capacity in Ah @ 1 amp discharge. I is the actual discharge current in amps.
