In the proposed method, two battery cells are periodically connected in turn to a mobile device and only one cell supply power while the other rests. Battery operation time of the connecting cell decreases due to ratecapacity effect, while that of the resting cell increases due to recovery effect. These two effects conflict each other, but recovery effect is generally larger than ratecapacity effect and battery lifetime is extended. It was found from the result that battery operation time increase about 7 by using alternating battery cell discharge. </abstract> <index>Open Science Index 82, 2013</index> </article>
