Abstract: In order to enable easy determination of whether a battery pack possessed by a user is one to be guaranteed or not and clearly differentiate an old battery pack from a new battery pack not to allow the old battery pack to be used in the field, when a battery diagnosis device determines that the battery pack is one to be guaranteed, information held by the diagnosed battery pack is written into a second battery pack different from the diagnosed battery pack.
