PROBLEM TO BE SOLVED: To provide a device and method of degradation determination capable of precisely grasping the remaining capacity and the remaining life of battery of the measuring objective group battery and portable terminal battery. SOLUTION: The power source 107 of the degradation determination device 100 supplies working power to it self while receiving AC power from the AC power source 109 and converting it into DC power. The connection part 108 connects the group battery 600 of the measuring objective battery. The setting part 102 receives information of discharge condition of the objective battery from a user. The discharge part 103 controls the discharge of the objective battery based on the information of the discharge condition, and measures the terminal voltage of the objective battery after the discharge. The operation part 105 calculates the remaining capacity based on the information of discharge characteristics in the battery data memory 104, information of discharge condition, and the terminal voltage of the objective battery, The display 106 displays the remaining capacity.
