Abstract : It is an object of the present invention to provide an electrochemical reserve battery in which the electrolyte is separately and safely stored in a shock and vibration resistant container. Another object is to provide a reserve battery having a compact configuration particularly suitable for use in air-launched buoys and the like. Still other objects are to provide electrolyte storage and transfer suitable for safe use with lithium batteries, to provide an auxiliary supply of high pressure gas for the positive transfer of electrolyte into the cell compartments of the battery, and to provide a reserve battery which is relatively simple to manufacture, maintain and operate. Briefly, these and other objects of the invention are accomplished with a chamber completely filled with electrolyte which is separated from adjacent cell compartments by a rupturable disk. A fully compressed bellows within the chamber maintains a low pressure in the electrolyte. A rigid spiral tube within the bellows contains high pressure gas releasable by a frangible cap connected through a short lanyard to the bellows.
