Abstract
A battery pack has a housing with a plug portion mateably receivable in a socket of a battery-powered power hand tool on which the battery back is designed to be mounted. The battery pack also has a connector cable with a connector plug at its distal end mateably receivable in the tool socket so that the battery pack can be disposed remotely from the tool. The battery pack can be mounted on tools with which it does not mate by use of an adapter having a plug portion mateably receivable in the tool socket, and an adapter socket mateably receiving the battery pack plug portion. Multiple battery packs may be interconnected on a wearable carrier and connected to the tool by a cable with a plug connector.
