METHOD FOR RECYCLING SECONDARY BATTERY

A method featuring the steps of determining a secondary battery collected from a user as to whether it is reusable when being handed over again to the user after recharged, by performing a simple inspection on a site where the battery is received and returned to the user, and transferring the battery 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 it has a reusable quality to the specified capacity, while the battery can be given back quickly.
