Battery pack for a hand-guided power tool

摘要

An exchangeable battery pack for an electric device has a housing with a first end face and a second end face opposite the first end face, wherein the first end is open. A housing cover closes off the first end face. Battery cells are disposed in the housing. Cell connectors electrically connect the cells with one another. An external electrical connector is disposed on the second end face. All of the battery cells are connected to the external electrical connector. The battery cells are charged and discharged through the external electrical connector. A cell holder secures several of the battery cells. An inner positional securing element is provided on an inner side of a sidewall of the housing and the cell holder interacts with the positional securing element.
