Allen's Battery
a.k.a. Professor Allen's Miniature Galvanic Battery
Medical Claims Healing via galvanic electricity

The Allen's Battery (or Professor Allen's Miniature Galvanic Battery) is an electro-therapeutic medical medallion, advertised as a generator of healing electric current in the wearer, produced by the reaction of the varying metals constituting the battery with the wearer's skin (as a galvanic response). It is identical in design to Boyd's Battery and the Sagendorph Battery, with "Allen" stamped on it in place of "Boyd" or "Sagendorph", and was sold primarily in Australia and New Zealand by Allen (and local agents).
