The cap has a first section with a raised contact receiving section. The raised contact receiving section has a side aperture into an area between the positive terminal and the raised contact receiving section. The aperture is generally perpendicular to the first section. The cap has a second section that snap-lock mounts onto the first end of the battery. ## Claims ### Claim 1 A battery cap comprising: a first section having a top surface disposed generally parallel to a top end of a battery and having a rim for contacting the top end of the battery and a raised contact receiving section with a single aperture through the first section into an area beneath the raised contact receiving section, the aperture being generally perpendicular to the top surface of the first section; and a second section integral with the first section, the second section extending generally perpendicular to the top surface of the first section for fixedly mounting the first and second sections to a battery. ### Claim 2 (depends on 1) A battery cap as in claim 1 wherein the cap is comprised of a molded dielectric polymer material. ### Claim 3 (depends on 1) A battery cap as in claim 1 wherein a section of the aperture has a general rectangular shape. ### Claim 4 (depends on 1) A battery cap as in claim 1 wherein the raised contact receiving section has a top with a ledge extending in front of the aperture. ### Claim 5 (depends on 4) A battery cap as in claim 4 wherein the raised contact receiving section has sloped side walls extending down from the top towards the rim. ### Claim 6 (depends on 4) A battery cap as in claim 4 wherein the ledge has a tapered leading edge for guiding a contact into the area beneath the raised contact receiving section. ### Claim 7 (depends on 1) A battery cap as in claim 1 wherein the aperture has a general "L" shape. ### Claim 8 (depends on 1) A battery cap as in claim 1 wherein the second section has a general ring shape. ### Claim 9 (depends on 1) A battery cap as in claim 1 wherein the second section has an inwardly raised ridge for snap-lock mounting in a recess along a side of the battery. ### Claim 10 (depends on 1) A battery cap as in claim 1 wherein the second section has a tapered leading edge and an interior raised area behind the leading edge for receiving a protective cover surrounding a majority of the battery. ### Claim 11 A battery assembly comprising: a battery having a positive terminal at a first end and a negative terminal at an opposite second end; a one-piece battery cap fixedly connected to the first end of the battery, the cap having a rim section over a rim portion of the first end of the battery and a raised center section over the positive terminal forming a contact receiving area between the cap and the positive terminal, the raised center section having a single side aperture substantially perpendicular to a center axis of the battery, the cap substantially enclosing the positive terminal except for the single side aperture through the raised center section. ### Claim 12 (depends on 11) An assembly as in claim 11 wherein the aperture has a general "L" shape. ### Claim 13 (depends on 11) An assembly as in claim 11 wherein the cap extends along the entire length of the battery. ### Claim 14 (depends on 11) An assembly as in claim 11 further comprising a protective cover attached to the battery that covers portions of the second end and a side of the battery. ### Claim 15 (depends on 14) An assembly as in claim 14 wherein the cap has a ring shaped section that is connected to the side of the battery. ### Claim 16 (depends on 15) An assembly as in claim 15 wherein the ring shaped section covers a portion of the protective cover. ### Claim 17 (depends on 11) An assembly as in claim 11 wherein the battery has a ring shaped recess on a side of the first end and the cap has a ring shaped protrusion that is located in the recess to fixedly mount the cap to the battery. ### Claim 18 (depends on 11) An assembly as in claim 11 wherein the raised center section has a top with a ledge that extends out over the side aperture. ### Claim 19 (depends on 18) An assembly as in claim 18 wherein a leading edge of the ledge is tapered. ### Claim 20 (depends on 18) An assembly as in claim 18 wherein the raised center section has side walls that taper out and away from the top.
