Remove six 6mm and two 2mm screws using a Phillips #0 screwdriver.
The screws on the battery can be hard to remove as they need to be unscrewed, stood up, then unscrewed fully. You can use the tweezers to pull up the screw in place. You'll know it's in the proper place when you go to unscrew it and it comes out smoothly.
