ABSTRACT:
In a battery-powered electronic apparatus having a microprocessor therein, any task is stopped running on the microprocessor in response to a check timing signal and, after the task is stopped running on the microprocessor, an output voltage of the battery is detected. Subsequently, after resuming the task running on the microprocessor, the remaining quantity of the battery is estimated based on the detected output voltage using a discharge characteristic of the battery.
