A method for judging a service life of a primary battery is disclosed, in which, by using a battery pack having a built-in microcomputer, a primary lithium battery is discharged at a given time, a voltage of the primary lithium battery is measured at the time of discharge, and such measured voltage is compared with a specified reference voltage, so that when the measured voltage is less than the reference voltage, the primary lithium battery is judged to have reached the end of its service life. And, the given time is a periodic timing.
