Abstract
A circuit for detecting the discharge level of a long life battery, such as a lithium battery, in which the battery is periodically subjected to an increased load for short durations of time. The periodic increases in load allows the end of battery life to be predicted and detected prior to the time the battery is fully depleted. Forecasting the end of battery life ensures that the battery will have sufficient energy to reliably operate the discharge level detection circuitry before the battery is fully depleted.
