A soldering jig comprises a shaped hole that fits a corresponding battery terminal, such as a square battery terminal, and provides a cavity for insertion of a solder wire. An opposite side from the cavity for insertion of the solder wire provides a blind hole for insertion of one end of the solder wire and a template for bending and cutting the solder wire to a correct length. Once cut, the solder wire is inserted into the cavity and is resiliently retained until the solder wire and jig are inverted and placed onto a hot battery terminal. Under pressure and residual heat the hot battery terminal, the solder wire melts, soldering an interface.

1. A post soldering jig for soldering a joint between a battery post and a battery terminal comprises: a durable, heat-resistant material forming a jig body;a shaped hole capable of accommodating the battery post, such that the jig body fits over the battery post when the battery post is inserted into the shaped hole;a first end of the jig body having a recessed portion, the recessed portion being disposed around the shaped hole and having a depth and perimeter length capable of receiving a wire having a wire diameter and a wire length, such that the wire makes good contact with the joint between the battery post and the battery terminal;a second end, opposite of the first end, the second end having a blind hole and a guide disposed at a distance from the blind hole, the blind hole having a depth and a diameter capable of accommodating the wire, wherein the depth of the blind hole and the distance from the blind hole to the guide provides the wire length, the wire length being selected such that the wire fits around the perimeter length, and the wire forms a continuous bead around the battery post at the joint between the battery post and the battery terminal, when the jig is used for soldering the joint between the battery post and the battery terminal. 2. The jig of claim 1, wherein the guide comprises a first channel having channel sides and a channel bottom formed in a first side of the second end and the blind hole extends downwardly into the jig body from a portion of the channel bottom. 3. The jig of claim 2, wherein the guide further comprises a second channel formed in a second side of the second end of the jig body, opposite of the first side of the second end. 4. The jig of claim 3, wherein an outer perimeter of the second end comprises a quadrilateral. 5. The jig of claim 4, wherein the first side is disposed at one vertex of the quadrilateral and the second side is disposed at an opposite vertex of the quadrilateral from the first side. 6. The jig of claim 5, wherein the quadrilateral is a square. 7. The jig of claim 1, wherein a portion of the shaped hole comprises a square cross section. 8. The jig of claim 7, wherein a round hole extends from the portion of the shaped hole that comprises a square cross section through the remainder of the jig body, such that the shaped hole is a through hole. 9. The jig of claim 1, wherein the jig body is comprised of a phenolic. 10. A method for using the jig of claim 1, the method comprising: inserting one end of a wire for soldering into the blind hole to the depth of the blind hole;bending the wire such that a bend is formed where the wire exits the blind hole;extending the wire from the blind hole to a guide, measuring a wire length;cutting the wire at the guide such that the wire has the wire length;reversing the jig body;inserting the wire into the recessed portion of the first end around the shaped hole, such that the wire diameter extends a distance above the surface of the first end and around the perimeter length;positioning the first end of the jig body over the battery post;inserting the battery post into the shaped hole, such that the wire makes contact with the joint between the battery post and the battery terminal; andforming solder around the joint between the battery post and the battery terminal. 11. The method of claim 10, wherein the solder provides a fillet at the joint. 12. The method of claim 10, further comprising preheating the battery post and the battery terminal. 13. The method of claim 10, further comprising shaping the wire, after the step of cutting the wire, into a square by removing the wire from the blind hole and using the jig to bend the wire into a square shape.
