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.

Abstract
A battery strength indicating and switch means on a battery which is coupled across the terminals of the battery and which is provided with an indicating means to indicate the strength of the battery and in addition, the battery strength indicating means is also provided with an in-line switch which can easily be depressed to complete the circuit so as to place the indicator means across the terminals of the cell and display the charge of the battery.

12. A battery having a battery strength indicator comprising:
-
a nonrechargeable dry cell battery having a first terminal and a second terminal;
a battery strength indicator in a first chamber formed between an upper, nonconductive layer and a lower, nonconductive layer attached to the battery, the indicator comprising a conductive layer and a heat sensitive color indicating material adapted to undergo a visible color change when the temperature of the conductive layer rises to a pre-determined temperature in response to a predetermined voltage output of the battery, and a first conductor adapted to be electrically connected between one end of the indicator and the first battery terminal; and
a battery switch comprising an upper resilient, nonconductive, deformable layer and a lower nonconductive layer on the battery, a switch chamber disposed between the upper, resilient layer and the lower, nonconductive layer of the battery switch, and a second conductor extending from the switch chamber and connected to the other end of the indicator, a portion of the second conductor within the switch chamber comprising a switch contact, the battery switch being biased in an electrically open position, whereby upon pressing of the resilient layer over the switch chamber, the switch contact will be placed in electrical contact with a conductive layer in electrical contact with the second battery terminal, thereby placing the indicator in electrical contact across the terminals of the battery to indicate to the user the strength of the battery. - View Dependent Claims (13, 14, 15)
