Abstract
A tester label for electrochemical cells employing two spaced apart electrically conductive electrochromic electrodes in which an ionically conductive electrolyte is disposed on the electrodes and in the space between the electrodes to produce a two-layer tester for batteries so that when the electrodes are applied to a power source, the electrochromic electrodes will undergo a chemical reaction and exhibit a change of color thereby producing a color contrast between them.
