In accordance with one aspect of the invention, a thin profile battery apparatus comprises at least two thin profile batteries conductively bonded to one another, with one of the batteries including portion which overhangs the other. In one implementation, the batteries comprise button type batteries. In one implementation, the two thin profile batteries are the same size and shape. In accordance with another aspect, a radio frequency communication device comprises a substrate having conductive paths including an antenna. At least one integrated circuit chip is mounted to the substrate and in electrical connection with a first portion of the substrate conductive paths. At least two thin profile batteries conductively bonded in series with and over one another and a second portion of the substrate conductive paths are included. One of the batteries has a portion which overhangs the other and is in electrical connection with a third portion of the substrate conductive paths. In but another aspect, a method of forming a battery powerable apparatus includes providing at least two thin profile batteries over one another. One of the batteries is conductively connected to a first node location formed on a surface of a substrate. The other of the batteries is provided to overhang the one battery and be electrically connected therewith. The overhang of the other battery is conductively connected with a second node location formed on the surface of the substrate.
