What Screwdriver Do You Need to Open a Nintendo DSi for Battery Replacement? None.
You do not need a screwdriver. The Nintendo DSi's back cover is secured by plastic clips, not screws.
How to Open the DSi Battery Compartment
Locate the Notch: Find the small indentation along the top edge of the back casing (near the shoulder buttons).
Use a Safe Pry Tool: Insert a plastic opening tool, a guitar pick, an old credit card, or a thin plastic spudger into the notch. Do not use metal knives or screwdrivers—they will scratch the casing and risk damaging internal components.
Gently Release Clips: Twist or slide the tool to pop the first clip. Work your way around the perimeter (top → sides → bottom), releasing each clip until the back panel lifts free.
Access Battery: The battery sits in a clearly marked compartment. It pulls out easily—note the orientation for the replacement.
Important Tips
Power off the DSi completely before starting.
Work on a clean, flat surface to avoid losing the tiny shoulder button springs (L/R) which can pop out when the back is removed.
Use a genuine Nintendo battery or a high-quality third-party replacement (e.g., Cameron Sino) for safety and longevity.
