Abstract
A button-type battery unit comprising an upper housing, a battery coupled to the upper housing, a printed circuit board and a lower housing. A positive battery terminal and a negative battery terminal are reflow soldered to the printed circuit board. The upper housing is coupled to the lower housing to enclose printed circuit board. The positive battery terminal and the negative battery terminal are positioned on the printed circuit board such that the upper housing moves along a single axis of translational movement when being coupled to the lower housing.
