The invention relates to a lead-acid battery performance test method comprising the steps as follows: loading a set experimental temperature to a lead-acid battery, and cyclically carrying out a charge-discharge experiment and a dismantling experiment of the lead-acid battery; acquiring the capacity data of the lead-acid battery after the charge-discharge experiment of the lead-acid battery is repeated multiple times; detecting whether the capacity data is within a set capacity range; and judging that the lead-acid battery passes performance test if the capacity data is within the set capacity range, or judging that lead-acid battery does not pass performance test. Only by acquiring the capacity data of the lead-acid battery in the process of experiment and analyzing the capacity data, the performance of the lead-acid battery can be tested. Less time is consumed, and the efficiency of lead-acid battery performance test is improved.
