A button type metal/air cell with a height increasing cap thereon to provide for multiple-cell batteries of varying heights. The cap is placed adjacent the cathode inlet of the cell and is accordingly apertured and preferably also contains a porous absorbent material for leakage prevention but which does not significantly affect air inflow rate. Cells, with protective height adjusting caps, are assembled into multi-cell batteries of varying heights with reduced incidence of leakage.
