A battery deterioration degree prediction apparatus comprising an obtaining unit and a controller. The obtaining unit obtains one or more histories of types of operation parameters for a target battery and reference batteries and a degree of deterioration of the reference batteries. The controller predicts a degree of deterioration of the target battery. Using map data where groups into which the reference batteries are classified and coefficients representing rates of change in the degrees of deterioration of the reference batteries are associated with each other. The groups in the map data are classified by a trend of histories of a first group parameter included in the types of operation parameters. The coefficients in the map data are derived based on the histories for the reference batteries and the degrees of deterioration of the reference batteries belonging to one of the groups that is associated with the coefficients.
