Abstract
A portable information handling system includes a battery having a pattern that aids in detection of battery swell, such as by capture of a visual image of the battery and pattern with a camera for comparison against a threshold of the pattern distortion that indicates excessive battery swell. For instance, the pattern is parallel lines of a strain gauge that detects strain introduced by battery swell. Distortion of the parallel lines by expansion of the battery due to swelling is detected by changes in distance between the parallel lines and confirmed with distances measured between the camera and the pattern by an infrared depth camera.
