Heating Blanket for the C-Max battery.

By Pam M.

Since the weather has turned colder and I don't have a garage, my C-Max miles per gallon has dropped almost five miles to the gallon. I know a cold battery drains faster and does not work effeiciently, why not wrap the battery in a blanket that has a thermastat that never lets the battery casing go below 50 or 55 degrees.? With all the technology out there it seems like this would be an easy thing to do.
