Storage battery electrolyte temperature measuring apparatus

摘要

There are described apparatus for measuring the temperature of the electrolyte material in a lead-acid storage battery without physical access to that material. 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 temperature of a brass connector placed in thermal contact with the battery negative post at a time immediately prior to connecting the analyzing apparatus to the battery and at a predetermined time thereafter and produces an output signal indicative of the electrolyte temperature in response to those measurements.
