Nintendo Switch 2 Battery Installation

Apply high-concentration (90% or higher) isopropyl alcohol to a cotton swab and wipe any adhesive residue from the battery well.

Use an opening pick or your fingernail to lift the foam strip off the top edge of the battery by its adhesive, not the foam itself.

Peel the entire sticker, including the foam, from the front of the battery.

Install the foam stickers in their original positions onto the new battery.

If your battery doesn't come with pre-installed adhesive, apply 5 mm‑wide strips of thin, double-sided tape to the flat area on the bottom of the battery. Don't install adhesive along the angled parts of the edges.

Remove all adhesive backings.

Align the battery with its well, ensuring the cable aligns with its cutout.

Carefully lower the battery into the frame.

Gently press down on the battery for around 20 seconds to adhere it to the frame.

Use your finger or the flat end of a spudger to press the flat-topped battery connector onto its socket until it's fully seated.
