Claim:
1. A self-dischargeable rechargeable high-voltage battery pack, comprising: a plurality of series-coupled energy storage elements; a housing enclosing and sealing said plurality of series-coupled energy storage elements with a plurality of exterior walls; an operational port coupled to a portion of a first particular one exterior wall of said plurality of exterior walls, said operational port providing an energy transfer with respect to said plurality of series-coupled energy storage elements; a self-discharger, responsive to a self-discharge signal, initiating an internal dissipation of energy at an intentional self-discharge rate of at least 5 W from said plurality of series-coupled energy storage elements while said self-discharge signal is asserted without said energy transfer through said operational port, wherein said internal dissipation of energy is disabled when said self-discharge signal is not asserted; and a battery precharger mechanism coupled to said plurality of series-coupled energy storage elements selectively limiting a current flow from said plurality of series-coupled energy storage elements in a first mode wherein said self-discharger includes said battery precharger mechanism in a second mode that constantly dissipates energy from all said series-coupled energy storage elements at once.
