I got my battery from Ebay this morning and installed it. It's charging now. It seems to be working just fine.
I first watched the Youtube video from Newpower99 for my Paperwhite 2. Turns out mine was nothing like theirs once I got the case off. And I really had to fight to get that case off. I ended up using a flat screwdriver since the plastic tool they provided just didn't get it done.
Once I got it apart it got pretty scary because I really had to figure out what to do. The video helped a lot but I had to figure out all the differences. Anyway I got it done. It took about 20 minutes and as far as I can tell it's all just fine.
During most of the process I was pretty sure my Paperwhite was a goner. I considered stopping and throwing it away. I really doubted I could get it back together properly. But I kept going just because I'm not going to be beaten by a bunch of plastic and it all fell into place at the end.
I'm pretty happy now. Overjoyed. I'll be bragging about what a genius I am for the next week or two.
