Battery residual value display device

The battery residual value display device includes: a battery information receiving module; an attenuation function determining module; a second residual value determining module; a graph output module configured to output a graph of which one axis indicates residual values of a battery and another axis indicates information on an elapsed time from a time of manufacture of the battery; and a display unit. The graph output module is configured to output: in the graph, a display indicating a first residual value; a display indicating boundaries between a plurality of residual value ranks obtained by dividing the residual values in accordance with a level of a second residual value; and a display indicating boundaries between a plurality of groups, indicating types of applications in which the battery can be used, obtained by dividing the plurality of residual value ranks in accordance with the level of the second residual value.
