Abstract
An electrolyte dispensing ampule for deferred action batteries comprises a spring having means at both ends thereof for forming a closed, generally cylindrical space inside the spring and a metal layer covering the spring to hermetically seal the space. An electrolyte solution is contained in the spring and is dispersed to activate the battery when set-back forces extend the spring and break the sealing layer.
