Battery removal on mid-2010 macbook pro

Macbook pro 15" Mid-2010:

I was curious about what would happen If I were to remove or replace the battery myself. I don't intend on doing this any time soon but when I was having a charging issue with my old power adapter, I took the back off and checked to make sure there were no loose connections that would be causing the problem. Turned out it was a bad power adapter. I noticed the battery said not to remove it and I know from the charts that this is one of the non-user replaceble batteries. Is there some kind of damage that would occure if I were to remove the battery myself. Just from the little glance that I saw when I was looking at it, it did not seem like it would be that difficult to remove. I have no intentions of removing it or replacing it at this time but was just curios as to what issues could occur If I did try to remove it myself. I can tell by looking at the battery that a replacement battery would have to come from apple but other than that I could not see any reason why I could not remove the battery myself.
