A high-energy power source with low internal self discharge for implantable use includes a multiplicity of rechargeable energy storage battery cells, a primary power source adapted to charge the energy storage cells, a switching system adapted to switch the energy storage cells between a parallel connection configuration for charging and a series connection configuration for discharging, and circuitry adapted to initiate charging of the energy storage cells only in response to an input signifying a need to discharge energy and to refrain from charging the energy storage cells until the input is received. In this way, the energy storage cells are maintained in a low charge state until discharge energy is required, the low charge state being at a level that promotes low internal self-discharge of the energy storage cells.
