Abstract
A pair of electrical terminals (72, 94) engage one or more cylindrical batteries (20, 22), each of which has a pair of circular opposite end surfaces (28, 30) defined by a pair of electrodes (26, 24), with one (28) of the end surfaces (28, 30) having a first radius (R1) and the other (30) having a second, greater radius (R2). The terminals (72, 94) define a pair of electrical contact surfaces (78, 96). The contact surfaces (78, 96) are spaced from each other along an axis (51) and face axially toward each other. A retaining structure (40) retains at least one battery (20) in an installed position centered on the axis (51) with the end surfaces (28, 30) engaged axially between the contact surfaces (78, 94). One (94) of the contact surfaces (78, 94) is spaced radially from the axis (51) a distance (D1) greater than the first radius (R1).
