Should You Store a Wii Balance Board on Its Side? No — Store Flat

Not recommended. Storing the Wii Balance Board vertically (on its side) long-term risks:

• Sensor damage: Four corner pressure sensors are calibrated for even, flat load. Side storage applies uneven shear force, potentially drifting calibration or cracking the sensor membrane.
• Warping: The polycarbonate top shell can bow under its own weight over months/years, affecting accuracy.
• Internal stress: Ribbon cables and PCB mounts aren't designed for lateral gravity load.

Best Storage Practice

1. Flat, on a stable surface (floor, shelf, original box insert).
2. Protect the surface: Use the original cardboard sleeve or a microfiber cloth to prevent scratches.
3. Cool, dry, out of direct sunlight: UV degrades plastic; heat warps; humidity corrodes contacts.
4. Remove batteries if storing >1 month (prevents leakage).

Short-term vertical lean (e.g., against a wall for a day) is fine. Weeks/months? Lay it flat.
