It takes a significant amount of pressure (in my opinion) to get the ifixit wii u gamepad battery to snap into place. When I successfully installed this battery, I laid the wii u gamepad screen down with the top of the gamepad facing me. Then I took the flat end of my ifixit spudger, and while pressing down on the battery connector at a 45 degree angle, I pushed the battery connector into the port. You'll be able to tell when the battery is connected all the way. However, this battery does NOT make a snap or click sound to let you know it's connected all the way.
