Depending on exactly where your battery is glued, you will (or you won't) have enough room for the plastic opening tool. I didn't and had to leverage off the other side. Unlike the front cover which required surprisingly little force to remove it (almost ripped the flex cords joining the front and the back), the battery required superhuman strength to remove, destroying the two spodgers (parts yet to be found they flew off with such force) and deforming the battery (which personally I would have no use for reusing in any case).
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
