An equipment is designed to test the residual characteristic of a battery set of an electric device. The equipment comprises a microcomputer main unit, an analog/digital converter, a decoder, at least one set of voltage testing lines, at least one relay, an analog switch, and a display. The voltage testing lines are connected with each battery of the battery set for measuring the terminal voltage of each battery. The analog switch is used to measure the discharge current, which is transmitted along with the terminal voltage via the analog/digital converter to the microcomputer main unit. One of the relays is activated by the microcomputer main unit via the decoder to retrieve the terminal voltage datum of one of the batteries of the battery set for computing the value of a residual characteristic by the microcomputer main unit. The value of the residual characteristic of the battery is digitally exhibited by the display.
