Abstract: The invention relates to a cell holder for holding cylindrical battery cells, where the cell holder comprises: a plurality of holding portions each of which has a bottom and sidewalls and thus forms a portion that is designed to receive and fix, around a base surface and, at least in part, a lateral surface, one battery cell in each case, where the sidewalls enclose the holding portions in each case; at least one contact surface, which is arranged in a contact region for the battery cell substantially perpendicularly to the bottom and is designed to be in planar or linear contact with a portion of a lateral surface of the battery cell when the battery cell is inserted; and at least one deformable contact portion, which is designed to deform when the battery cell is inserted into the corresponding holding portion.
