Zusammenfassung:	There is provided a battery life diagnosis device includes: a storage unit configured to store a usage time of a battery measured at each time point and a measured value of a deterioration index indicating deterioration of the battery measured at each time; and a processing unit configured to diagnose a life of the battery. The processing unit obtains a time change amount of the deterioration index based on the usage time of the battery and the measured value of the deterioration index, obtains a prediction function of the deterioration index for each battery based on the time change amount of the deterioration index, obtains a predicted value of the deterioration index based on the prediction function of the deterioration index, and diagnoses the life of the battery based on the predicted value of the deterioration index.
