I had the same thing happen to me a Long Time ago with a Rev"2" CE2.
I tried all the things listed here and nothing worked. I was going to chuck it when I thought, "You Can't Break the Broken."
So I submerged the battery in 98% Isopropyl Alcohol and shook it 10 of 15 times. Blew it out and put it on the top of my Stero Reciever to dry for a couple of days.
When I remembered it, about a week later, I dialed 9-1 on my cell phone and then put my finger over the 1 as I took a hit. It worked fine. In fact, it outlasted another 510 Auto I had.
I'd ONLY recommend doing this if you are going to Chuck the Battery in the Trash Anyway.
