Abstract

A method for testing battery connectivity in a battery-backed up system, the method includes inducing a step increase in a battery bus voltage, and monitoring a magnitude of a corresponding current pulse of a battery charge due to the step increase in the battery bus voltage, where the magnitude of the current pulse provides an indicator of battery connectivity.
