Abstract
An electronic apparatus which detects when a battery having a different characteristic is mixed in a plurality of batteries accommodated therein. An average voltage Vper battery of plural batteries connected in series and an average voltage Vper battery at a connecting point halfway of those connected batteries are detected. A difference in voltage |V−V| between the average voltage Vand average voltage Vis compared with a tolerable voltage difference ΔV. If it is determined that a battery having a different characteristic is mixed, the operation of the apparatus is interrupted and an alarm is displayed or the supply of power is shut down.
