BATTERIES WITH NON-RECTANGULAR SHAPES FOR AUGMENTED REALITY DEVICES, AND SYSTEMS AND METHODS OF USE THEREOF

An example augmented-reality headset comprises a frame portion, a temple arm portion coupled with the frame portion, and a metal-encased battery cell having an exterior surface that defines a non-rectangular shape. The metal-encased battery cell is configured to be housed within the temple arm portion, and the non-rectangular shape of the exterior surface follows an interior shape of an internal surface of the temple arm portion. The augmented-reality headset also comprises one or more artificial-reality processing or presentation devices, wherein at least one of the one or more artificial-reality processing or presentation devices is configured to receive power from the metal-encased battery cell.
