Claim:
A reserve battery, comprising: a battery case having an electrolyte compartment and an electrode compartment; wherein said electrolyte compartment is adjacent a first end and said electrode compartment is adjacent a second end; a first battery terminal connected to said battery case at said first end, wherein said first battery terminal comprises an external button; a second battery terminal connected to said battery case at said second end; an ampoule movably positioned within said electrolyte compartment; an electrolyte contained within said ampoule; a first bias member internally located within said battery case between said external button of said first terminal and said electrolyte compartment opposite said electrode compartment; electrodes positioned within said electrode compartment; a porous cutter supported within said battery case between said electrodes of said electrode compartment and said ampoule of said electrolyte compartment; wherein an external force applied to said external button of said first terminal causes said first bias member to transfer an internal force to said ampoule to cause said ampoule to rupture via engagement with said cutter thus allowing said electrolyte to release and contact said electrodes thus activating said battery.
