Claim 0:
1. A battery assembly comprising:
a battery pack;
a battery pack seat for mounting the battery pack in a locking direction, the battery pack seat having a base for achieving an electrical connection with the battery pack; and
a sealing member having a thickness and an outer circumferential periphery disposed in a direction perpendicular to the thickness, the sealing member being disposed between the battery pack and the base for preventing water from entering the battery pack and the base, the base having a first terminal being arranged on an upper surface of the base matched with the battery pack, the battery pack having a second terminal matched with the first terminal, the second terminal being arranged on an under surface of the battery pack, one of the first terminal and the second terminal passing through the sealing member to create an electrical connection with the other one of the first terminal and the second terminal, a protrusion portion being arranged on one of the under surface and the upper surface, the protrusion portion including a wall extending in the locking direction and annularly arranged around the one of the first terminal and the second terminal, the wall being spaced radially inwardly from the outer circumferential periphery of the sealing member so that the protrusion portion, upon mounting of the battery pack to the battery pack seat, axially compresses the sealing member in the locking direction along the wall and around the one of the first terminal and the second terminal to thereby reduce an amount of force required in the locking direction between the battery pack to the battery pack seat to prevent water from entering the battery pack and the base.
