Patent Images
1. A battery tester for testing a battery under test installed in a device without requiring direct access to or removal of the battery under test, comprising:
- a stereo plug configured for insertion into a stereo jack on the device to thereby complete a circuit including the battery under test and a load circuit in the device to which the battery under test supplies power;
first circuitry configured to measure a battery voltage corresponding to the battery under test;
second circuitry configured to measure a load current corresponding to the load circuit to which the battery under test supplies power;
control circuitry configured to generate one or more signals representative of remaining battery life for the battery under test with reference to the battery voltage and the load current; and
a display configured to generate a representation of the remaining battery life using the one or more signals.

19. A stereo plug for insertion into a stereo jack, comprising a tip conductor, a ring conductor, and a sleeve conductor, wherein the stereo plug has a profile such that the tip conductor is narrower than a maximum width of the widest portion of the stereo plug, and wherein the ring conductor is also narrower than the maximum width of the stereo plug, and wherein the stereo plug further comprises a first dielectric insulator insulating the tip conductor from the ring conductor, and a second dielectric insulator insulating the ring conductor from the sleeve conductor, a portion of the first dielectric insulator increasing in width from the tip conductor to the maximum width and then decreasing in width from the maximum width to the ring conductor, a portion of the second dielectric insulator increasing in width from the ring conductor to the maximum width.
