Question: How many CCA is required to Start a Exp in U.P of Mich in Late December. I currently have 675 CCA. Is this sufficient?
Thanks.

Yes. I was thinking of installing a Interstate w/ at least 850. I wasn't sure if was necessary because my Auto-Silver is just over a year old. But, I believe its better to be safe than sorry w/ temps in the low teens to 0 in Dec.
I understand Wal-Mart has a line of Batterys called Evermaxx.
I may look into one if $$ becomes an issue.
