Abstract
A battery diagnostic method for monitoring the status of a battery in an electrical system and continuously providing a relatively accurate prediction of battery condition and performance, more particularly, a self-adjusting method for providing the best possible prediction of a battery's reserve time before, during, and after a battery discharge. The method of the present invention utilizes different prediction methods depending on what state the electrical system is in; that is, before, during or after a battery discharge. By determining what state the system is in, the most effective prediction method can be utilized to provide an accurate battery reserve time. By providing a relatively accurate continuous reserve time prediction, the method helps prevent a complete loss of power in an electrical system relying on a battery to supply the system's electrical power.
