  • Battery test module
    Patent number: 7058525
    Abstract: A storage battery includes a battery housing and a plurality of electrochemical cells in the battery housing electrically connected in series to a positive terminal of the battery and a negative terminal of the battery. A first connection is coupled to the positive terminal of the battery and a second connection is coupled to the negative terminal of the battery. A battery test module is mounted to the battery housing and electrically coupled to the positive and negative terminals through the respective first and second Kelvin connection. A display or other output is configured to output battery condition information from the battery test module.
    Type: Grant
