Abstract
A battery retention latch (50, 140) comprises an annular ring member (52, 142), a release button (54, 172, 174) and a spring arm (156, 190, 192, 194, 196). The annular ring (52, 142) retains a battery pack (26) in a cordless device (20, 120) regardless of the annular orientation of the battery pack (26) about a casing axis. The spring arm (56, 190, 192, 194, 196) maintains the ring (52, 142) in a normally engaged position and upon depressing the push button (54, 172, 174), the battery (26) may be removed from the device (20, 120).
