First of all, DON't USE All CAPS.
Second, don't you dare turn it on.
Third, dispose of the battery through a recycling facility or any place that accepts old batteries.

Make sure you place the battery pack (make sure to isolate it) on surfaces you don't care about burning, like a metal box maybe (lipo bags may not be available). Do not place the battery on your valuables or your person, as there's a chance of fire and the burns are nasty from lion batteries.

Ok ill wrap it aluminum and isolate it

You're probably going to die… Nah just kidding, just don't touch it
