A method of testing characteristics of battery set includes a multicircuit voltage tester having a plurality of voltage testing line sets, which are coupled respectively with a positive terminal and a negative terminal of a battery unit of the battery set, which is subsequently permitted to discharge to a load for a predetermined period of time and which is subsequently recharged. During such times when the discharging and the recharging of the battery set are under way, the multicircuit voltage tester is capable of scanning, reading and writing repeatedly the voltage data of each battery unit. Such data are stored in a memory and are plotted equidistantly to form a chart comparing the voltage characteristics of the battery set. The characteristics of each battery unit can be determined by observing the change in space between the characteristic curves in the chart.
