There are described apparatus for detecting the presence of a defective cell in a lead-acid storage battery. The apparatus is included as a part of a larger apparatus for analyzing the condition of the battery and its suitability for further use in automobile lighting, starting, and ignition applications. The apparatus measures the terminal potential of the battery when it is subject to a constant resistance load. If that potential is found to increase more than a predetermined amount during a time interval following the application of the load, the battery is known to have at least one defective cell.
