A workpiece, such as a treatment workpiece, for use with a non-powered appliance is disclosed. The workpiece includes a rechargeable or non-rechargeable battery integrated into the workpiece housing. The workpiece in some examples can be configured such that the battery is neither removable nor replaceable. The capacity of the battery can either be selected so as to provide at least a single use of the workpiece or to correspond to the recommended replacement period (e.g., 90 days) of the workpiece.
