Gauge effect battery tester
First Claim
1. A battery tester, comprises:
- a first voltage divider; and
a plurality of parallel battery tester elements, comprising;
a voltage controlled display having a first terminal coupled to the first voltage divider; and
a second voltage divider coupled in parallel with the first voltage divider and coupled to a second terminal of the voltage controlled display, with the second voltage divider comprising;
a second voltage divider coupled in parallel with the first voltage divider and coupled to a second terminal of the voltage controlled display, with the second voltage divider comprising;
a non-linear device that switches state based on a voltage across the second voltage divider to electrically control switching of the voltage controlled display for the element of the parallel battery tester, with the non-linear devices having different switching voltage characteristics to switch the voltage controlled display of each parallel tester element at different voltages.

Abstract
A battery includes a cell having an outer circumference and a battery tester. The batter tester can be of different types. One type a segmented display tester includes a first voltage divider and a plurality of parallel battery tester elements including a voltage controlled display having a first terminal coupled to the first voltage divider and a second voltage divider coupled in parallel with the first voltage divider and coupled to a second terminal of the voltage controlled display. The second voltage divider also includes a non-linear device. A second type of battery tester is also disclosed. This type is a variable type and has a first voltage divider including a non-linear device coupled to a plurality of resistance elements and a voltage controlled display having a first terminal coupled to the first voltage divider and a plurality of second terminals coupled to the plurality of resistance elements.
