摘要： Described are a lead-acid battery system and life estimation method that can improve reliability by more accurately estimating degradation of a lead-acid battery regardless of its cause. A transition determination unit determines switching of charging/discharging process of the battery, and a current value determination unit detects a change in a discharge current value during a discharge period, When a change is detected, a calculation unit calculates a capacitance turn-over (CT) value on the basis of a discharge current value acquired for each section divided by the change, and a degradation determination unit determines a degradation degree of the battery using the CT value.
