Abstract: In a system and method for detecting venting of a sealed storage cell, the sealed storage cell comprises a container with a sealing cap adapted to be detached from the container and move in the presence of gas overpressure inside the container to allow venting of the storage cell. The detection system comprises a printed circuit board with a central portion designed to be situated opposite the sealing cap, a peripheral portion surrounding the central portion and connected to the central portion by a hinge adapted to flex during movement of the sealing cap, and at least one frangible portion adapted to break upon movement of the sealing cap. An electrical printed track connects the peripheral portion to the central portion through the hinge and frangible portion(s), and is designed to be broken upon breaking of the frangible portion(s) following movement of the sealing cap.
