An electrical-energy-supplying device having an extended storage life includes a thermoelectric (TE) working module which has a hot junction and a cold junction. A storage battery for supplying electrical energy is thermally connected to the cold junction to transfer heat from the battery to the hot junction of the TE module when a voltage of proper polarity and magnitude is applied to the TE module. A thermal sensor is thermally connected to the battery and electrically connected to a cooling control circuit to cause application of the voltage to the TE module when the battery temperature exceeds a selected temperature level. The storage life of the battery may be extended by maintaining the battery temperature below the selected temperature level.
