1. A battery having a battery strength indicating means to indicate the strength of the battery comprising a battery having a first terminal and a second terminal;

  • a battery indicator and switch means comprising a non-conductive base layer, a non-conductive top layer disposed over the base layer, a first chamber formed between the top layer and the base layer, and a second chamber spaced from the first chamber and formed between the top layer and the base layer;

    indicating means disposed in the first chamber;

    first conductive means electrically connected to one terminal of the battery and to one end of the indicating means;

    second conductive means connected to the opposite end of the indicating means and extending into the second chamber;

    third conductive means extending from within the second chamber and extending to contact the other terminal of the battery; and

    whereby the second conductive means and the third conductive means in the second chamber are spaced apart and said second chamber being deformable so that upon pressing of the second chamber the second conductive means will electrically contact the third conductive means thereby placing the indicating means in electrical contact across the terminals of the battery to indicate the strength of the battery.
