<p>The purpose of the present invention is to improve, using a simple configuration, mechanical and electrical connection precision so a battery pack is properly connected, both mechanically and electrically, to a battery-powered device. A battery pack detachably mounted in a battery-powered device for supplying power to the battery-powered device to operate the device includes at least one rechargeable secondary battery (1), a battery case (31) housing the secondary battery (1), a mounting mechanism for mechanically mounting the battery case (31) in the battery-powered device, an electrical connection connected electrically to the battery-powered device for supplying power to the battery-powered device, and a pack circuit board (74) securing the electrical connection. The battery case (31) is divided into a first casing and a second casing, the pack circuit board (74) is secured to the inside surface of the first casing, and the mounting mechanism is installed so the mounting mechanism is at least partially exposed on the surface of the first casing.</p> |
