So I took the battery out today and had it tested. It failed even for a paper weight. Because it was chinsy Wal-Mart brand I took it back and capitalized on the 3 year replacement. Took my money back (after two and a half years of service fo' FREE!!!) and will go get a decent battery tomorrow.
After its fired up I'll post back on the rough idle.
