Abstract

A wet cell battery, where a first cell in a wet-cell battery includes a set of anode electrodes and a set of cathode electrodes, and where electrically conductive debris accumulates on a surface inside the first cell to an expected height. An anode electrode in the set of anode electrodes has an anode end closest to the surface, and a cathode electrode in the set of cathode electrodes has a cathode end closest to the surface. A first gap distance between the anode end and the surface is different from a second gap distance between the cathode end and the surface. When the electrically conductive debris accumulates up to the expected height, the debris fails to make simultaneous electrical contact with the anode electrode and the cathode electrode due to the different gap distances.
