Battery end cap

A battery comprising:

• an electrical source;
• a casing;
• a cap terminal, the cap terminal comprising an external conductive surface and an internal conductive surface;
• and
• a pressure sensitive switch comprising an air gap between the internal conductive surface of the cap terminal and the electrical source, the pressure sensitive switch is configured to bias the internal conductive surface of the cap terminal from being in electrical communication with the electrical source,
• wherein the pressure sensitive switch is in a closed position when a sufficient external pressure is applied to the battery end cap and wherein the pressure sensitive switch is in an open position without the sufficient external pressure.

A battery end cap comprising:

• a first end and a second end, the second end for engaging a portion of a battery;
• a cap terminal, the cap terminal comprising an external conductive surface and an internal conductive surface;
• and
• a pressure sensitive switch comprising an air gap between the internal conductive surface of the cap terminal and an electrical source of the battery, wherein when the battery end cap is installed on the battery, the pressure sensitive switch is configured to bias the internal conductive surface of the cap terminal from being in electrical communication with the electrical source,
• wherein the pressure sensitive switch is in a closed position when a sufficient external pressure is applied to the battery end cap and wherein the pressure sensitive switch is in an open position without the sufficient external pressure.

A method for creating a battery having an end cap comprising:

• providing the battery;
• providing the battery end cap, the battery end cap comprising,
• a first end and a second end, the second end for engaging a portion of a battery;
• a cap terminal engaging the first end, the cap terminal comprising an external conductive surface and an internal conductive surface;
• and
• a pressure sensitive switch comprising an air gap between the internal conductive surface of the cap terminal and an electrical source of the battery, wherein the pressure sensitive switch is configured to bias the internal conductive surface of the cap terminal from being in electrical communication the electrical source,
• wherein the pressure sensitive switch is in a closed position when a sufficient external pressure is applied to the battery end cap and wherein the pressure sensitive switch is in an open position without the sufficient external pressure;
• and
• mounting at least a portion of the second end to the battery.
