The battery cover uses a snap-fit design plus pre-drilled screw holes. The snap allows quick, tool-free access for everyday battery changes, while the reserved holes let you add your own screws later if the tab ever becomes loose from long-term use. This is intentional, better engineering—not a missing screw.
