Abstract
An electronic battery tester for testing a storage battery is provided. The tester includes a pair of Kelvin connectors that can electrically couple to terminals of the battery. Also included, is a source that can apply a time varying forcing function to the battery through the Kelvin connectors. A sensor that electrically couples to the Kelvin connectors can sense a response of the storage battery to the applied forcing function and provide a response signal. An analog to digital converter digitizes the response signal. Processing circuitry converts the digitized response signal into multiple Fourier components and determines noise in the response signal from a subset of the multiple Fourier components.
