More Information
Summary:A battery pack for an electric power tool has at least one cell arrangement with a plurality of individual battery cells that are arranged such in a predetermined total number of battery cells upright adjacent to one another for forming a cell container that cell axes of the battery cells are approximately perpendicular to a common reference plane. Cell connectors electrically conductingly connect cell ends of the battery cells. The battery cells of the cell container include a core cell and neighboring cells surrounding the core cell. Points of intersection of the cell axes of all of the neighboring cells with the reference plane are positioned on a closed, approximately elliptical curve. A number of neighboring cells is greater than one third of the total number of the battery cells of cell container.
