Abstract: In an electrical storage battery composed of a plurality of electrochemical cells, a keyed linkage system provides for the series connection of the cells in a prescribed order. The system includes the cell terminals, which may be in a stud or tab form, a tooth projecting outwardly in each cell between the terminals, and connecting links which are secured to the terminals of adjacent cells.

The sieve carrier is conveniently associated with the cell by being provided in a layer, e.g. in a holder, around the cell.

Abstract: If one of a series string of battery cells fails on open circuit, the circuit through all of the cells is broken. An automatic means for by-passing the failed cell maintains the circuit and allows operation of the string to continue (at a lower no-lead voltage). The potential difference across the failed cell is utilized to heat a body of a conductive liquid so that it expands, ruptures the ampoule containing it and fills the gap between two conductors, thereby completing a shunt circuit.
