1. A cell tester device for an electrochemical cell having a first terminal and a second terminal of opposite polarity;

  • a substrate;

    a first electrically conductive electrochromic electrode disposed on said substrate;

    a second electrically conductive electrochromic electrode disposed on said substrate and spaced from said first electrochromic electrode;

    an ionically conductive electrolyte extended in contrast with at least a portion of each electrode;

    said first electrochromic electrode adapted to electrically contact the first terminal of the cell; and

    said second electrochromic electrode adapted to electrically contact the second terminal of the cell so that when the first electrode makes electrical contact with the first terminal and the second electrode makes electrical contact with the second terminal, both electrodes will undergo a chemical reaction to exhibit a visible contrasting color change.
