Abstract : Using an improved bridge circuit, the equivalent circuit components of a nickel-cadmium cell were measured at frequencies of 10, 20, and 200 cps at various states of charge. The measurements were made on a group of vented cells. It was found that the equivalent circuit components, especially R sub c at 10 and 20 cps changed with time. A correlation of R sub c with residual capacity was found after cells were stored for more than four hours after discharge. (Author)
