A battery output monitoring device (100) includes: a battery characteristics estimating unit (101) which estimates an internal resistance value and a current-less voltage of the battery (200); a guard power calculating unit (103) which calculates, based on at least the internal resistance value, a guard power to be greater than a required power to correspond to at least a decrease in a state of charge and progress of polarization of the battery (200) during a predetermined period, the guard power being a power required to be a currently available output power of the battery (200) so as to output the required power at a predetermined minimum voltage during the predetermined period; and a determination unit (104) which instructs an external alarm device to perform an alarm operation when a difference between the current power and the guard power is less than a predetermined value.
