The present invention provides a method (100), an apparatus (400), and a communication device (700) for automatically maintaining a state of full charge in a charge storage device, such as a secondary battery (414), to which a fixed load (412) is momentarily connected. Since the load is fixed, a predetermined amount of charge is removed from the charge storage device each time the load is connected. A counter (404) is incremented while the load (412) is connected. From the count, the amount of charge that must be replaced can be determined. As the charge is replaced the count is decremented. |
