There is provided a battery remaining-life estimation apparatus that includes a memory, and a circuit. The memory is configured to store information about a polarization-voltage curve of a secondary battery, the information being stored with a correlation with a current value and a temperature of the secondary battery. The circuit is configured to estimate a remaining power of the secondary battery, the remaining power being estimated based on a discharge curve of the secondary battery. The circuit obtains the polarization-voltage curve based on the information in the memory, the polarization-voltage curve being correlated with the current value and the temperature of the secondary battery. The circuit also estimates the discharge curve by subtracting the obtained polarization-voltage curve from an open-circuit voltage curve obtained for the secondary battery.
