Charging dead battery ( 12 v or 6 v)
So my car's battery died, I blame me for not driving it for a week and the weather dropping to the mid 30's at night , i went to crank it and there wasn't a Volt of charge, usually, when the battery is low on power it will sputter out and give a half-assed crank , what i do is turn the charger to 12 V "CRANK" and she fires right up , I quickly disconnect the charger and the cables because I'm scared of frying anything. Today It was dead dead, as in 0 volts so I Tried the 12v CRANK setting and all I got was a click, no crank, immediately disconnected the system. Should charge it at 6v or 12 v , the CRANK setting just adds extra amperage.

You should charge it with the "12V" setting (which is really 14.4 or should be).
Unfortunately, when a lead acid cell is deeply discharged, lead phosphate forms, blocks surface reactivity at that site and diminishes the capacity of the battery.

I charged it for half an hour, the car started right up, sadly I think Toruki is right, my dad gifted the battery to me three years ago, it was new but the battery has never been used until 4 months ago . The two times it had died i left the AC/ Radio on and it drained it within a day .

The cold really stresses batteries. And showing 0V is a bad sign . Face palm, I wrote phosphate where I should have said sulfate.
