PROBLEM TO BE SOLVED: To provide a secondary battery inspection method configured to improve accuracy of quality determination, and an inspection apparatus.SOLUTION: A secondary battery inspection method for determining quality of a secondary battery on the basis of the amount of voltage drop in an aging step includes: setting a threshold of the amount of voltage drop, on the basis of aging time and temporal changes of battery voltage due to self discharge of a non-defective secondary battery; and determining quality of the secondary battery on the basis of a result of comparing the amount of voltage drop in the aging step with the threshold. |
