Abstract

PROBLEM TO BE SOLVED: To accurately judge the deterioration while saving the labor by calculating the voltage difference between the no-load voltage measured value of a storage battery and the load voltage measured value at the time of connecting the battery to a predetermined load resistor, and comparing it with a reference value. SOLUTION: When a storage battery 3 to be judged for its deterioration is connected to a body 1 via connecting terminals 4, 5 and the power source of a general purpose personal computer 2 is turned on, a batter model selecting screen is displayed on a monitor screen 17. When a select signal for selecting a special model for the battery 3 is input from a keyboard 19 while observing the screen 17, the other screen for confirming the input model is displayed on the screen, and hence the displayed special model is confirmed and a confirmed signal is input. The no-load voltage and load-voltage of the battery 3 are calculated by a voltmeter 6, and whether the voltage difference exceeds a reference value or not is judged. If the difference exceeds the reference value, the effect that the replacement of the battery is required due to the deterioration is displayed on a display unit 18.
