i was replacing the screen and during the procedure i scratched the battery and you can see a little silver is it safe to proceed or did i just &&^& it up? and must replace the battery too?

if you did not puncture the “Silver” foil, you’d be safe. Just patch it with a small piece of electrical tape over the scratch. But if it went deeper than a scratch, I’d replace it as there would be a danger of it causing a fire.
