<p>A device for estimating the remaining life of a battery which supplies stored electricity to an electric device is provided with a storage section where the relation between the reference cumulative sum of discharge voltage drops from the start of the battery discharge and the reference remaining life value, a discharge voltage drop cumulating section which cumulates the discharge voltage drops from the start of the battery discharge, and a remaining life estimating section which estimates the remaining life of the battery from the actual cumulative sum of the discharge voltage drops and the reference cumulative sum in the storage means.</p> |
