    Worth trying in the camper?
    The battery is fine and now just parallel it with your new one.

    Ranga, could you posting up the BM2 graphs?

    It would be interesting to see how the battery voltages varied, from while charging to when you disconnected the load.

    Left the load on all day, and tonight at 2100 it was at 12.33V. Looks like a linear discharge. Still good to use?

    Sounds good to use, to me.
    Keep agitating it with a multi-stage charger to keep it healthy.

    test it at its rated discharge capacity after youve float charged it, let it sit for 24 hours.

    most deep cycles will have a 5 10 or 20 hour rate.
