A portable therapeutic heating device is provided that may be readily worn and transported by a user. A flexible heating unit is attached to a body part and is capable of raising the skin temperature of that body part to about 102°-108°F. The flexible heating unit includes a plurality of distinct sets of electric resistance heating elements. The flexible heating unit is connected by a flexible tape to a battery pack which is mounted to the approximate center of gravity of the user\s body. A switch is mounted on the battery pack, and provides for selection of which sets of electric resistance heating elements will be energized by a battery received by the battery pack, to thereby vary the amount of heat applied by the heating unit to a body part. The switch is mounted in a cutout formed in a casing defining the battery pack. A pair of rechargeable lead-acid “D”batteries are desirably received by the battery pack, and circuitry is provided for indicating when the voltage of a rechargeable battery received by the battery pack reaches a predetermined value below the rated value of the battery. A printed circuit board is mounted completely covering the batteries in the battery pack casing, between the batteries and the casing top, with all of the necessary electrical components operatively connected to the printed circuit board.
