You might have an interesting theory.
You must remember the importance of specific gravity. A discharged battery will have a specific gravity near that of water witch will freeze at 32* F. Once I went skiing in Idaho when the temp went to 36* below. Of course at this temp the battery couldn't power a flashlight.I took the battery to the condo and put it in a sink full of hot water twice. With the battery at a temp of about 80*,I fired up my 1980 Celica. In my opinion Toyota makes the best of the rice burners. In this temperature you always leave a stick in neutral. You always run the engine a short time and shut it off several times til the oil flows. By the way I depend on Interstate Bateries. Now I'll shut and wait for the cold country experts to tell me better. This is just my way.
