    Abstract: A rechargeable battery assembly includes a rechargeable battery having a positive terminal and a negative terminal, and a rigid electrically conductive frame electrically connected to at least one of the positive terminal or the negative terminal of the rechargeable battery. The rigid electrically conductive frame is bent along multiple axes and includes a plurality of conductive frame members that are mechanically coupled together. The rigid electrically conductive frame surrounds the rechargeable battery on at least five sides, thereby providing structural stability to the rechargeable battery assembly during storage and use. 20465621_1 (GHMatters) P45880AU02
