In an embodiment of the techniques presented herein, a method includes applying an excitation signal to an inductive sensor spaced apart from a conductive surface of a battery, determining a battery swelling metric based on a response, in the conductive surface, to the excitation signal, and controlling a device comprising the battery based on the battery swelling metric.",
