Battery discriminating method, and electronic device

A battery discriminating method discriminates between smart battery packs (30) and dry battery cell packs (10) with a simple structure. A dry battery cell pack (10) is composed of a case for storing a plurality of dry batteries connected in series, plus (11) and minus (12) 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 (13) provided in the case. A predetermined voltage is supplied the terminal (13) for discriminating the battery of a battery pack via the resistor, and the voltage value of this terminal is detected to discriminate the type of the battery pack according to the detected voltage value.
