Abstract

A method features the steps of determining whether a secondary battery collected from a user is reusable when being handed over again to the user after being recharged, by performing a simple inspection on a site where the battery is received and returned to the user. The battery is transferred to another site for additional detailed inspection to further examine whether the battery is reusable when the determination is such that quality up to the specified capacity is not assured if the battery is given back for further usage to the user only after recharging it. The processes described in the above method can ensure the user that the battery has a reusable quality to the specified capacity, while the battery can be given back quickly.
