Electrical power source battery tester

摘要

An electrical charge detection device for measuring the electrical charge of a dry cell battery comprises electrically conductive arms joined with a rivet pin at their proximal ends with curved tips at their distal ends. The junction formed by the proximal ends has a light source mounted on the planar top surface and is in electrical contact with the pin. The curved tips at the distal ends of the arms are angled to form inward curved prongs that connect with the polar ends of a power source such as a battery. When the arms are squeezed together, one tip contacts the cathode of the battery and the other touches the anode so that any charge in the battery will travel up the arms thereby lighting the bulb. The degree of brightness illuminated by the bulb is indicative of the electrical strength or power remaining therein.

主权项

1. An electrical charge detection device comprising:
a) at least two pivotally-movable, electrically conductive arms joined with a rivet pin at their proximal ends with curved tips at their distal ends; b) a light source mounted on the planar top surface of the proximal end of a first upper arm that is in contact with said pin; c) at least one rubber washer disposed between the proximal ends of said arms with a hole in middle for passage of said pin; d) at least one metal clip or contact disposed between the washer and the interior planar surface of the first upper arm and a second lower arm that is contiguous with said pin and has a second hole for passage of said pin; c) wherein the curved tips at the distal ends of the arms are equivalently angled to form inward curved prongs that will connect with each polar end of a power source.
