Quick release battery replacement

The Quick-release Battery Pack I purchased for my Generation 2 Video Doorbell has a single screw hole centered on the bottom. I removed my Generation 2 doorbell from the faceplate but it has 2 crew holes and a small speaker on the bottom. Every videao I bring up on the internet shows simply snapping the faceplate off the battery but mine unit has 4 small screws in the rear on each side holding the battery in place. Help!
