Moisture barrier for battery with electrochemical tester

The combination of an electrochemical cell and a cell condition indicator, said indicator having at least one moisture sensitive component;

• wherein said electrochemical cell comprises a casing, a negative terminal, and a positive terminal;
• wherein said condition indicator comprises an indicator cell including a film-laminate comprising an anode layer, a cathode layer and an electrolyte layer in operative association with each other;
• and wherein said condition indicator is located proximally adjacent the outside surface of said casing;
• the combination further comprising a moisture barrier protecting said indicator cell;
• and wherein at least one of the anode and cathode of said indicator cell provides a visual indication of the condition of said electrochemical cell.
