A system for monitoring the energy performance of a secondary battery, and a method therefor, are disclosed. A micro-processor (32) is used to compute the energy capacity during the use of the battery by charging and discharging, thereby determining the decrease in the battery capacity. This data is provided to the user and is transmitted to a battery residue capacity measuring means, so that the battery may be charged if needed. The total discharged energy amount is stored in a ROM, and analog signals obtained from a power supply means are converted to digital signals, while an actually used total energy amount is stored in a non-volatile RAM (35). The value stored in the RAM (35) is compared with the value stored in the ROM 33, thereby computing the decrease of the battery capacity. This decrease in the battery capacity is transmitted through an output processing section (37) to a display means (40) for display so that the user and the battery residue capacity measuring means (60) know the decrease in battery capacity. Therefore, the monitoring of the energy performance of the battery can be determined even during the operation of the system. Based on the value of the decrease of the battery capacity, the replacement time of the battery can be determined, and therefore, system malfunctioning due to power failure can be prevented.
