1. A method of evaluating performance of a CEW energy cell comprising:
inserting a CEW energy cell into an input port of a portable test device; performing a two-tier DC load test on the CEW energy cell by sequentially applying at least two different loads to the CEW energy cell, including a low constant current load and a high constant current load; evaluating a voltage signature under the two-tier load test; determining at least one internal resistance value based on said voltage signature; and outputting at least one indicator relating to CEW energy cell status based on said determining.
