Abstract
Provided is a simple secondary battery tester that obtains, without applying an AC signal for determination based on capacitance, the capacitance of a secondary battery from time characteristics of a current flowing to the secondary battery and a terminal voltage and determines whether the secondary battery is degraded based on the capacitance thus obtained.
