Abstract
Abstract A kit for indicating the polarities of terminals of a battery including a pair of markers formed of wafers made of a hard durable plastic and having plus or minus signs formed on one of the sides thereof, and a double-sided foam adhesive tape attached to the other sides thereof. The markers are readily secured to the surface of a battery near appropriate terminals by simply peeling off a laminate attached to the adhering side of the adhesive tape and sticking the marker on a clean spot on the surface of a battery.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
72 words
A device for indicating the polarity of a battery terminal, comprising: a durable hard plastic disc having an indicating side and an adhering side; a heat resistant adhesive layer on the adhering side of the disc adapted to affix the marker to the surface of a battery; and a raised portion on said indicating side of said wafer including a raised indicium of one of a plus sign or a minus sign.
Claim 2
Independent Claim
72 words
A device for indicating the polarity of a battery terminal, comprising: a durable hard plastic disc having an indicating side and an adhering side; a heat resistant adhesive layer on the adhering side of the disc adapted to affix the marker to the surface of a battery; and a raised portion on said indicating side of said wafer including a raised indicium of one of a plus sign or a minus sign.
Claim 3
Dependent Claim
47 words
A device as set forth in claim 1, wherein said adhesive layer comprises a double-sided foam adhesive tape permanently affixed on one side to the adhering side of the marker, the other side of the tape adapted to affix the marker to the surface of a battery.
Claim 4
Dependent Claim
13 words
A device as set forth in claim 1, wherein said disc is circular.
Claim 5
Dependent Claim
40 words
A device as set forth in claim 3, further including a laminate layer on said other side of the tape to preserve tackiness of the tape until such time as the marker is affixed to the surface of a battery.
Claim 6
Dependent Claim
87 words
A retrofit kit for indicating the polarity of positive and negative terminals of a battery, comprising: a pair of markers, each marker including a disc formed of a hard durable plastic material and having an indicating side and an adhering side; a raised indicium on each marker on the indicating sides thereof, one marker having a raised plus sign, the other marker having a raised minus sign; and an adhesive layer on the adhering side of each marker adapted to affix the marker to a battery surface.
Claim 7
Dependent Claim
87 words
A retrofit kit for indicating the polarity of positive and negative terminals of a battery, comprising: a pair of markers, each marker including a disc formed of a hard durable plastic material and having an indicating side and an adhering side; a raised indicium on each marker on the indicating sides thereof, one marker having a raised plus sign, the other marker having a raised minus sign; and an adhesive layer on the adhering side of each marker adapted to affix the marker to a battery surface.
Claim 8
Dependent Claim
23 words
A kit for indicating the polarity of positive and negative terminals of a battery according to claim 5, wherein said disc is circular.
Claim 9
Dependent Claim
49 words
A kit for indicating the polarity of positive and negative terminals indicating the polarity of positive and negative terminals of a battery according to claim 6, wherein the markers are of different colors, the marker having the plus sign being red, the marker having the minus sign being black.
Claim 10
Dependent Claim
51 words
A kit for indicating the polarity of positive and negative terminals of a battery according to claim 7, wherein the indicia on the markers are colored white and wherein the disc is approximately 1 inch in diameter and the indicia are raised from the indicating surface by at least 0.06 inches.
Claim 11
Dependent Claim
32 words
A kit for indicating the polarity of positive and negative terminals of a battery according to claim 8, further comprising a display card upon which the markers are temporarily secured and displayed.
Claim 12
Dependent Claim
47 words
A device as set forth in claim 5, wherein said adhesive layer comprises a double-sided foam adhesive tape permanently affixed on one side to the adhering side of the marker, the other side of the tape adapted to affix the marker to the surface of a battery.
