Abstract:
A battery pack for use with a battery-driven power tool includes three battery cells in which two out of three are arranged horizontally in parallel to and in alignment with each other in a lower case and the remaining one battery cell is vertically arranged in an upper case. The upper case of the battery pack is inserted, in use, into a battery pack receiving space formed in the grip portion of a power tool. Therefore, the grip portion can be made thin and usability of the power tool is enhanced.
