<p>A battery and a chamber holding the battery are provided.The battery has a case with the same size of a cylindrical case or a flat column case of general alkaline battery.An annular groove positive electrode is provided on the top of the case, and a project flat negative electrode same as the negative electrode of a general alkaline battery is provided on the bottom of the case.The battery has the positive electrode being different from the positive electrode of a general alkaline battery, so that the battery will not be easily misused.The chamber includes derivate cells of positive and negative electrodes, a column positive electrode derivate units and an annular positive electrode derivate element electrically isolated each other are provided on the positive electrode derivate element. The battery of the invention and a general alkaline battery all can be installed in the chamber to supply power, so the chamber has excellent compatibility.</p> |
