Abstract

A battery having a complete discharge mechanism includes a spring-biased switch with an element spring-biased from the switch and acts to close the switch when in a fully extended position. A block is position above the element with a passageway aligned with the element. A flexible positioned between the element and the passage prevents the element from extending into the passage. The tab extends through the battery casing. When pulled the tab allows the element to extend into the passage thereby closing the spring-biased switch and completing the discharge circuit.

Claims

1. A battery having a complete discharge mechanism;

said mechanism including a switch having a spring-biased element wherein said element acts to close said switch when said element is fully extended;

said battery having two spaced electrical components creating a passage;

said passage aligned with said element and adapted to receive said element;

a tab extended between said blocks, positioned between said element and said passage, said tab preventing said element from extending into said passage; and

said tab extending through a casing of said battery;

whereby pulling said tab allows said element to enter said passage and close said switch thereby activating said complete discharge mechanism.
