I’m betting you haven’t opened a battery pack in your entire life. Why not go watch a couple of videos on laptop battery packs, what’s in them, and how to fix em? Maybe you’ll learn something instead of foulmouthing and fudding.
Me? I work with 18650s every day, protected and unprotected cells; I charge em, I fix em, and I know it’s pretty hard to puncture em; that being said, if op is anything like you he’s probably much better off leaving it to a qualified repairman or just buying new.
But thanks for the heads-up, I’ll add a safety warning to my advice; that better? 🙂️
