  "textContent": "A method for estimating lifespan of a battery in accordance with the present invention, comprising steps of: fully discharging the battery; partially charging the fully discharged battery under a predetermined charging condition; acquiring pieces of voltage information at multiple specific points of measurement time while partially charging the battery; and calculating remaining capacity of the battery by using the acquired pieces of voltage information. An apparatus for estimating lifespan of a battery in accordance with the present invention, comprising: a reference data-storing unit for storing reference data that become a basis of estimating the lifespan of the battery; a charge/discharge-controlling unit for fully discharging the battery to estimate the lifespan of and partially charging the battery under a predetermined charging condition; a voltage information-acquiring unit for acquiring pieces of voltage information of the battery at multiple specific points of measurement time while partially discharging the battery; and a remaining capacity-calculating unit for calculating remaining capacity of the battery by using the acquired voltage information and the reference data.",
