A tip for you and anyone else doing this: do yourself a favor and get a heat gun or other tools required to at remove and recycle the battery, before your house burns down.

I've had various old phones, laptops speakers etc. that became bloated in storage because an internal lithium ion cell was halfway ruptured.

And once you do that it's usually trivial to pop out and destroy the motherboard or storage device, especially as you don't care about doing so destructively. Then you can recycle the rest.
