Abstract
Impedance measurements on 23 Ah Ni-Cd cells at various residual capacity levels are described. These have been made using non-inductive connections coupled directly to a potentiostat and a frequency response analyser.
The capacitive reactance at 0.39 Hz provided the best residual capacity indicator.
