The secondary cell (24) or an article, suchas a portable transceiver (10), containing a secondary cell is protected from harmful effects of microwave energy using a Faraday cage (12) and an antenna (16) disposed outside the Faraday cage picks up the energy which is rectified using s Schottky barrier diode (26). Optionally, the secondary cell may be disposed outside the oven (18) and the rectified current is supplied from the interior of the oven by way of conductors and/or a suitable connector.
