Abstract
A rechargeable battery pack for a hand-held power tool, including a housing having at least first and second housing components, the pack including at least one cell holder, accommodating at least two battery cells in a parallel/series circuit, the battery cells each including two end faces extending perpendicularly to a longitudinal axis; and a pack electronics system including contact elements for establishing electrical connection between the pack and a power tool. The cell holder includes sleeve-like insulating walls, corresponding to the battery cells at least in some areas, to prevent electrical contact between the battery cells. A method for manufacturing a pack for a hand-held power tool, the cell holder including sleeve-like insulating walls, having cylindrical cell openings for accommodating the battery cells, the battery cells being pressed into the cell openings so that a form-locked and force-fit connection is established between the cell holder and the battery cells.
