PASSIVE COOLING DEVICE FOR EXTENDING BATTERY LIFE Abstract of the Disclosure An electrical-energy-supplying device having an ex- tended storage life includes a finned heat sink; a battery for supplying electrical energy is thermally connected to the finned heat sink by a copper or aluminum bar for transferring heat from the battery to the heat sink. The heat sink is enclosed in a chimney structure which has an air inlet in a lower portion and an outlet in an upper portion thereof. The chimney lower portion has a heat and light absorbing coating which causes air to flow in a path between the air inlet and outlet by convection. The heat sink is positioned in the air flow path the facilitate heat dissipation from the sink to the atmosphere. The storage life of the battery may be extended by maintaining the battery temperature below a selected temperature level.
