  • Pico scope battery test

    The Picoscope has a diagnostic function that will quickly test battery.

    But interesting points are the current draw needed to initiate cranking and how low it pulls battery voltage down.

    thats some big initial current draw , and yet they only fit 490CCA batteries at the factory??

    even more reason to bulk charge at a higher voltage for longer , gives the battery time to recover

      It’s only for a fraction of a second though.
      The 490cca battery would have to be complete minimum rating they could get away with. So once battery starts failing you can really see the need for up grading knowing it wants to pull 1000 amps initially. Without taking any consideration of freezing winter mornings down here on the other side of the wall.
