Abstract: A battery pack provides ease of assembly and disassembly from a portable transceiver yet retains its new-like latching properties for an extended period of time. The battery pack is generally rectangular in shape and includes alignment slots and a projecting rib section on one edge surface for aligning both with counterpart projecting ribs and an alignment slot located on the housing of the portable transceiver. The battery pack also includes a latch mechanism attached to a generally planar surface on the battery housing for securing the battery housing to the housing of the portable transceiver. The latch mechanism includes both an outwardly projecting guide member for guiding the battery pack into a cradle on the portable transceiver and a latch member within the perimeter of the outwardly projecting guide member for securing the battery pack to the portable transceiver.
