Enhanced battery edge detection devices, systems, and techniques are described herein. During an inspection process, an inspection system controls one or more non-visible light sources to illuminate a battery installed in an electronic device. The illumination activates a reflective pigment applied to at least a portion of an edge of the battery. The inspection system controls one or more cameras to capture at least one image of the illuminated battery installed in the electronic device. The at least one image is processed to detect the edge of the battery and to measure a gap size between the edge of the battery and a region of the electronic device proximate the edge of the battery. The electronic device and battery are flagged for further inspection if the measured gap size is below a threshold indicative of a zero gap event.
