Abstract
A method for producing a battery tester label is disclosed. The method includes forming an inserted tester device and a base layer, which are combined together to form the battery tester label. The resulting tester label can be applied to a battery. Also disclosed are methods for producing a plurality of battery tester labels disposed on a common releasable liner. The resulting array can be stored for subsequent application to batteries, cut into relatively long strips for rolling and storage, or immediately applied to batteries.
Claims7
A battery tester label for an electrochemical cell having a housing, said battery tester label comprising:
- a label substrate;
- a conductive circuit attached on said label substrate, said conductive circuit including first and second switch segments, said first switch segment adapted to be placed in electrical contact with a negative terminal and said second switch segment adapted to be placed in electrical contact with a positive terminal to generate an amount of heat related to the remaining capacity of the electrochemical cell;
- a thermochromic material applied over said conductive circuit and responsive to the heat generated by said conductive circuit for changing visual states to provide an indication of the remaining capacity of the electrochemical cell;
- and
- an insulating layer disposed between said conductive circuit and the housing of the electrochemical cell, said insulating layer defining a plurality of cavities extending through the thickness thereof to form thermally insulating air pockets between said conductive circuit and the housing of the electrochemical cell.
