    yes 14.4 at the battery and on the Trigger-Metric controller.

    The 21% also registered on the controller, although after checking the fuse at the battery, the display is
    now - - - -.

    Talked to tech support, he said I must have a loose connection. did have slightly loose nut on one of the batteries but it didnt change the - - - display on the controller.

    The -212 amp hours is also off the controller.
    Put the rig outdoors and plugged in the power cable, out of town for a few days, so will see where I stand when I return.
    Then I'll take out at least one battery and have it load tested.
    Some people I talk to say 20% SOC on the AGM isn't deadly, others say it's probably toast.
    I'll find out and let you know.

    Many thanks for all your help,
    John

    If the batteries are true deep cycle AGM (with no mention of Marine or cold cranking amps in the spec since these are dual purpose batteries and not true deep cycle) and SOC is at 20% after a short period of use (not storage) and then fully charged back soon after discharge the batteries do well. Not meeting these requirements eats into battery life and capacity.

    A good deep cycle battery test measures actual Ahr delivered at C20 discharge rate and I do not know where to take battery to run this type of test. Quick battery testers may provide some information but they are not designed for a deep cycle test.

    Hit the reset button on the Tri-Metric Controller, batteries went to 100%.
    Tested the system by opening and closing the slides, SOC went to 93%, little while later returned to 100%.

    Figure I'm ok, will see how quickly they drain next time we're boondocking.
