Abstract: The invention relates to a storage battery unit (1) with a battery cell (2), having a terminal (3), with edges (6) and an outside insulation (5) also enclosing the edges (6). According to the invention it is provided that a non-conducting, elastic element (4) is positioned on the terminal side between the battery cell (2) and the insulation (5), so that the terminal (3) is set back with respect to a level (7) of the elastic element (4), wherein the insulation (5) fixes the elastic element (4). A stable hold of the storage battery unit (1) in a housing is thus achieved with simultaneous mechanical protection of electrical contacts.

Abstract: The invention relates to an insert (1), which can be inserted into a storage battery part (2) of an electrically operated tool, in particular a hand-guided tool with at least one handle for holding the tool, wherein the insert (1) comprises several battery cells (3), which are connected to one another in a current-conducting manner. According to the invention it is provided that the insert (1) has an openable housing (4) in which the battery cells (3) are inserted, wherein the battery cells (3) are connected in a current-conducting manner to conductor bars (5) attached to the inside of the housing (4). Furthermore, the invention relates to a storage battery part (2) with an insert (1) of this type as well as an electrically operated tool, comprising the storage battery part (2).
