There is provided a low-battery detection reference voltage table for memorizing the correspondence between current values and low-battery detection reference voltage values, which is obtained from battery voltage characteristic curves corresponding to different current values. Further, there is provided a low-battery reference voltage correction table for correcting the low-battery detection reference voltage in accordance with a voltage variation. Referring to the low-battery detection reference voltage table on the basis of the value of current output from the battery, the low-battery detection reference voltage corresponding to the current value is obtained. The voltage variation is found from the currently measured battery voltage and the previously measured battery voltage which is memorized. On the basis of the voltage variation, the correction voltage is found with reference to the low-battery reference voltage correction table. The found correction voltage is added to the low-battery reference voltage, thereby correcting the low-battery reference voltage. When the measured battery voltage is lower than the corrected low-battery detection reference voltage, the low-battery stated is determined.

A low-battery detection warning method comprising the steps of: a) generating a discharge current signal related to a discharge current value outputted from a battery; b) generating a low-battery detection reference voltage from the discharge current signal; c) generating a first and a second voltage signal related to a first and a second voltage value of the battery determined at sequential times; d) employing electronic processing means to determine a difference between the first and second voltage signals; e) employing said electronic processing means to modify the low-battery detection reference voltage in accordance with the determined difference and battery voltage characteristic curves corresponding to different charge time periods, so as to make constant a time period from the time a low-battery stage was determined to the time when a device driven by the battery fails to operate normally, irrespective of a charge time for the battery; f) employing said electronic processing means to compare the modified low-battery detection reference voltage with the first voltage signal, and determining the low-battery state when the first voltage signal is lower than the modified low-battery detection reference voltage; and g) generating a detection warning signal when the low-battery state has been determined to exist.
