Abstract:
The present invention relates to on-cell battery tester structures, to improved and/or to more informative charge indicator arrangements, and to methods for making and/or producing same. In one embodiment, the on-cell battery testers of the present invention are thermochromic in nature and comprise an insulator layer that contains, among other items, glass microspheres, polypropylene beads or microspheres, or a combination of both. In still another embodiment, the on-cell battery tester of the present invention comprises a printed insulator layer that contains, among other items, glass microspheres, polypropylene beads or microspheres, silica or a combination of any two or more thereof. In still yet another embodiment, the present invention relates to an charge indicator arrangement that conveys to an individual among other things, an improved, or more accurate, indicator of charge level, and to a method of making same.
