Claim 0:
1. A method of assembling a battery comprising:
positioning a feedthrough insulator cap on a feedthrough of the battery,
wherein the feedthrough insulator cap comprises:
a brim comprising an annular disk extending substantially within a plane, the brim having an interior edge and an exterior edge; and
a crown integrally formed with the interior edge of the brim, wherein the crown extends above the plane of the brim in a first direction; and

wherein the battery comprises:
an enclosure defining the interior of the battery and a feedthrough aperture open to an exterior of the battery, the feedthrough comprising:
a ferrule extending through the feedthrough aperture and coupled to the enclosure;
an insulator extending through the ferrule to the exterior of the battery; and
a pin extends through the insulator from the interior of the battery to the exterior of the battery, and wherein the insulator electrically insulates the pin from the ferrule;

a first electrode disposed within the enclosure and electrically coupled to the pin;
a second electrode disposed within the enclosure and separated a distance from the first electrode; and
an electrolyte disposed between the first electrode and the second electrode; and

heating the feedthrough insulator cap to reflow a material of the feedthrough insulator cap onto at least a portion of a ferrule, at least a portion of an insulator, and at least a portion of an interior segment of a pin.
