A label for an electrochemical cell with a condition tester for the cell integrated with the label to form a label/tester composite is disclosed. The label/tester composite has a thermochromic material in thermal contact with an electrically conductive material. A substructure containing a cured conductive material and preferably also a thermochromic material is formed on a releasable web and transferred from the releasable web to the inside surface of the heat shrinkable base film. A partition coating may be applied over the transferred conductive material. Preferably, a sheet of paper or plastic film having a large window opening therein for entrapping air is applied over the partition coating and aligned over the heat generating portion of the conductive material. The label/tester composite is applied to the cell housing with the insulating paper or plastic film with window opening against the cell housing. The tester may be activated by depressing one or two regions on its surface thereby connecting the conductive material to the terminals of the cell, whereupon the conductive material becomes heated causing a change in appearance of the thermochromic material to indicate the condition of the cell. |

DETAILED DESCRIPTION What is claimed is: 1.
In combination, an electrochemical cell and a label/tester composite; said cell comprising positive and negative terminals and a metal housing, a portion of said metal housing forming one of said terminals; said metal housing having a cylindrical wall with first and second shoulders at respective ends thereof; said label/tester composite being attached to the cell housing; said composite including a film around said housing, said film having a thermochromic material disposed on the side of the film facing said housing, an electrically conductive material in thermal contact with the thermochromic material, said conductive material being between said thermochromic material and said housing, and means for thermally insulating said conductive material from the cell housing, wherein said insulating means comprises a substantially electrically nonconductive material, and wherein said label/tester composite comprises means for enabling at least one end of the composite to be heat shrunk evenly over one of said cell shoulders, said means for at least one end of the composite to be heat shrunk evenly over one of said shoulders comprises at least two conductive fingers protruding from said conductive material, said composite further comprising a partition coating between said conductive material and said electrically nonconductive material, wherein a portion of said partition coating forms a plurality of protruding ribs, wherein said conductive fingers rest on said ribs, wherein said ribs define therebetween a plurality of cavities through which said conductive fingers may be manually pushed in order to electrically contact said conductive fingers with one of said terminals.
2.
The combination of claim 1 wherein said electrically nonconductive material has an opening therethrough through which a portion of the conductive material may be manually pushed to electrically contact said portion of the conductive material with the cell housing.
3.
The combination of claim 2 wherein the tester is activatable by exerting manual pressure over both said conductive fingers resting on said ribs and said portion of the conductive material over said opening and wherein said tester is deactivated when said manual pressure is removed
