Storage battery for vehicles, has battery test module that is coupled to two post extensions to form Kelvin connections between module and extensions, respectively, and display for outputting battery condition information

摘要

The battery has an electrochemical cell in a housing (18) connected electrically between a positive (12) and a negative (14) post. Two post extensions are coupled to the respective posts. A battery test module (16) is coupled to the extensions to form Kelvin connections (38,40) between the battery test module and the post extensions, respectively. A display outputs battery condition information from the module.
