RECHARGEABLE BATTERY PACK Abstract of the Invention A rechargeable battery pack that is easily installed and removed without the use of tools and with assurance that the correct polarity of the batteries will be established. A plurality of rechargeable batteries (54) are contained by a top cover (50) and a bottom cover (52). The bottom cover includes a pair of locating holes (65, 67) and a pair of recessed female connectors (66, 68) that are connected to the batteries to provide terminals of opposite polarity. The female connectors (66, 68) and the locating holes (65, 67) are arranged for complementary mating engagement with a pair of male connectors (42) and a pair of locating pins (20, 22), included in an electrical coupling (12) of a device to be powered. The top cover (50) includes a locating hole (55) that iscooperatively aligned with one of the locating holes (65) in the bottom cover sothat one of the locating pins (20) of the electrical coupling may be received thereby. To prevent improper insertion of the battery pack, the locating pins (20, 22) are configured differently from one another and the locating holes (55,65, 67) are configured complementary thereto. To avoid inadvertent damage to the sides of the batteries during installation, the top and bottom covers include tubular skirts (57, 69, 70) that guide the locating pins. The longer of the two locating pins (20) has a threaded end (40) that receives a retaining nut assembly (14) to firmly secure the battery pack in place. To minimize mechanical stress on the electrical connections, the male connectors (42) are mounted on a circuitboard (46) that floats relative to the locating pins (20, 22).
