The present disclosure relates to a method for estimating a state of health (SOH) of a battery and a battery system providing the same. According to the present disclosure, the battery system includes: a battery; and a battery management system (BMS) configured to obtain degradation conditions related to degradation of the battery at each predetermined monitoring cycle, determine a relational expression representing a relationship between a total energy amount of the battery and a state of health (SOH) of the battery according to the degradation conditions at the each monitoring cycle, and estimate an SOH of the battery according to the relational expression, wherein the total energy amount of the battery is the sum of charge energy and discharge energy of the battery.
