Abstract
A battery discriminating method discriminates between smart battery packs and dry battery cell packs with a simple structure. A dry battery cell pack is composed of a case for storing a plurality of dry batteries connected in series, plus and minus electrodes which are provided in the case and connected to the poles of the series-connected dry batteries, and a resistance element of which one end is connected to a predetermined connecting point of the series-connected dry batteries and the other end is connected to a terminal provided in the case. A predetermined voltage is supplied to a terminal for discriminating the battery of a battery pack via a resistor, and the voltage value of this terminal is detected to discriminate the type of the battery pack according to the detected voltage value.
