A battery assembly for use in an electronic device is provided. The battery assembly may include a battery cell (e.g., a rechargeable battery cell), a battery connector for providing power from the battery cell to the electronic device, and a flex circuit electrically coupling the battery cell to the electronic device. The battery connector may be located adjacent the battery cell, and may include one or more alignment mechanisms for ensuring that conductive pads of the battery connector align properly with corresponding conductive elements of the electronic device. The battery cell may be fixed to the electronic device using an adhesive layer (e.g., double sided tape) placed between the cell and the electronic device. A tab may extend beyond the periphery of the battery cell to allow a user to pull or peal the battery cell from the electronic device for replacement or repair. In some embodiments, a tool may be used to grasp the tab.
