A battery strength tester used on a battery which has indicating means to indicate the strength of the battery and switching means which can easily be employed to complete a circuit so as to place the indicator means across the terminals of the battery and display the charge of the battery and wherein said switch, after a predetermined interval or temperature is reached, automatically opens to break the electrical contact across the battery terminals. A light emitting material employed as the indicator material is another special feature of the battery strength tester. |

DETAILED DESCRIPTION The above and other objects and advantages, which will be apparent to those skilled in the art, are achieved in the present invention which is directed to, in a first aspect, an improved battery comprising a battery and a battery-strength tester having indicator means controlled by a switching means which switch when activated is adapted to be in the on position for a predetermined interval during which the indicator is electrically connected to the battery and provides an indication of the strength of the battery.
After the switch is turned on, for example by pushing and removing one's finger, it automatically turns off after a predetermined interval, during which interval the user is provided with a visual indication of the strength of the battery.
The switch means is normally in the off position and in an "on" position electrically connects and completes a circuit between the battery and the indicator means for a desired interval after which it reverts to its original off position.
An electronic switch which when activated stays on for a desired interval, e.
g.
, 3-10 seconds, then automatically shuts off may be employed.
Any other switching devices which can be controlled for a certain interval may suitably be used.
Likewise, any indicator means which can be activated by a flow of electric current may be employed.
In a preferred embodiment shown further herein, the improved battery having a battery strength tester comprises a dry cell battery having a first terminal and a second terminal; a battery indicator formed in a layer attached to a side of the battery which undergoes a visible change when a predetermined electric current flows through the indicator and a first conductor electrically connected between the indicator and the first battery terminal; and a battery switch comprising a resilient, nonconductive, deformable layer disposed over the side of the battery, a switch chamber formed beneath the resilient layer, and a second conductor extending from the chamber and connected to the indicator, the portion of the second conductive lead within the switch chamber comprising a switch contact, the battery switch being biased in an electrically open (off) position
