Abstract: A battery pack for selective attachment to a receptacle includes a housing enclosing a battery, a handle extending from the housing and defining an aperture between the housing and the handle, and a latching arrangement coupled to the housing and engageable with the receptacle for inhibiting the battery pack from being removed from the receptacle. The latching arrangement includes a latch member and an actuator movable relative to the housing from a first position to a second position to move the latch member from a latched position to and an unlatched position. The actuator is at least partially located within the aperture when the actuator is in the first position.

Abstract: A backpack vacuum cleaner configured to be carried on a user's back includes a housing enclosing a suction source, a dirt separator in fluid communication with the suction source, a shoulder strap coupled to the housing, and a battery receptacle located on the housing. A battery is removably coupled to the battery receptacle to provide power to the suction source, and the battery includes a battery housing and a handle extending from the battery housing. The battery can be decoupled and removed from the battery receptacle with one hand while the backpack vacuum cleaner is positioned on the user's back.
