Some of you might remember that my battery blanket was chewed by a mouse in the beginning of the winter. I am wondering if it is a big deal if I just get rid of it. I am assuming it is for protection from the cold but I wanted to make sure it is not there to protect the battery from engine heat. My car is only driven in the summertime so I am hoping I can just toss it. I am afraid to know how much Ford charges for the thing.
