Abstract

The present application is directed toward a method and system for conserving battery power in low power systems. According to one aspect of the invention a battery (88) with a low power processor (110) is used to shut off the monitor circuit (120) that determines the charge remaining on a battery (88). Periodically the low power processor (110) will wake up and power on the monitor circuit (120) to determine the remaining charge of the battery (88). According to another aspect of the invention there is a safety override circuit. The safety override circuit is a fail safe that allows charge to flow from the battery (88) when there is a fault with the low power processor (110) for example if the low power processor (110) fails to wake up.
