    How many VDC does a 12v battery drop for every 1 degree farenheight below the optimum ambient temperature of 77 degrees farenheight?

    I haven't hear about any temperature coefficient of the resting voltage, I only know the charging voltage should rise with around 1V for every 30ºC drop in temperature.
    The loaded voltage would drop with the temperature however, due to the internal resistance increasing.

    This told me all I needed to know. It may tell you most of what you need to know too. :)
