Abstract
An electric power tool includes a drive source, a rechargeable battery that supplies power to the drive source, a voltage meter that measures voltage of the rechargeable battery, a temperature meter that measures temperature of the rechargeable battery, and a drive control unit that regulates the power supplied to the drive source from the rechargeable battery to drive the drive source. If the battery temperature measured by the temperature meter is lower than or equal to a predetermined temperature when the battery voltage measured by the voltage meter is lower than or equal to a predetermined voltage, the drive control unit drives the drive source differently from normal driving that is performed if the battery temperature is higher than the predetermined temperature when the battery voltage is higher than the predetermined voltage.
