Abstract: A warming apparatus in which a flexible battery is intimately associated with a heating element by thermo-coupling the heating element to the surface of the flexible battery. The flexible battery is formed in the shape of garments such as gloves or socks with a heating element attached thereto, which provides the advantage of increasing the electrochemical activity of the battery, permitting the battery to provide a heat sink for the heating element, as well as eliminating lengthy connections between the battery and the heating element, and eliminating bulky and often injury producing batteries.
