This invention relates to high energy density batteries, of a reserve type, capable of long storage lifetime. An object of this invention is to provide a reserve battery more appropriate to a projectile fuze application. In such application, the battery must be activated only when the fuze is fired. Reserve batteries, as lithium one for example, are convenient but the firing of the fuze does not ignite the activating system. So, battery false ignition could happen. This invention solves the above-mentioned drawback by using the fuze firing to trigger off the battery ignition. For this purpose, this invention proposes a reserve battery comprising a cell-stack of electrodes with an annular shape, a liquid reserve ampoule containing the electrolyte at the centre of said cell-stack, an activating system which breaks the said ampoule at a predetermined acceleration level, and housing in which this said cell-stack, this said ampoule and this said activating system are placed.
