Abstract

A dual voltage battery tester for testing both 1.5 volt and 9 volt batteries is printed on a thin substrate with a reversible thermo-chromatic material in thermal contact with carbon heating elements. The heating elements use the same carbon resistive ink for bolt voltage ranges and is printed as a single pass.

Claims

1. A 1½

volt and 9 volt battery tester printed on a thin substrate with a reversible thermo-chromatic material in thermal contact with carbon heating elements where s the heating elements use the same carbon resistive ink, and where the carbon resistive ink for both voltage ranges is printed as a single pass.

2. A battery tester as in 1) where the 1½

and 9 volt printed circuits share a common silver buss bar.

3. A battery tester as in 1) where the heating elements and thermo-chromatic indications change in the same visual manner to indicate status of battery charge.

4. A battery tester as in 3) where a reticule or scale is the same for the 1½

volt and 9 volt indications

5. A battery tester as in 1) where a grid pattern carbon resistor is printed to increase the resistance or sheet resistivity to reduce the dimensional ratios required to handle the 1½

volt and 9 volt distances between the printed silver buss bars.

6. A battery tester as in 1) using a folded series of shorter carbon segments with silver connections printed normal to the main buss bars to construct the longer electrical path length carbon heating elements in a shorter tester footprint.

7. A standoff space between the 9 volt and 1.5 volt heating elements to provide thermal isolation between the two circuits and prevent thermal crosstalk from causing miss-indications.

8. A dual voltage battery tester as in 5) with continuous taper heating elements with silver conductive buss bars running along both sides of the tapered heating elements, and a shared silver conductive buss bar between the heating elements, providing a percent analog indication of battery charge status.
