The battery no longer works but I’ve kept it plugged in and used it for streaming music at work the last few years. Today it’s in an infinite loop of rebooting and I noticed the glass popped out!

Unplug that and very carefully dispose of it according to whatever laws apply where you live. That’s an insane fire hazard.
Yep. That thing needs to be outside far from any flammable structure and material NOW.
The closest place to me that accepts hazardous batteries without being paid is over an hour away from me.
So the spicy pillows I have are contained in a metal waterproof container that’s buried under bricks in an unused section of my driveway. At least if they go, they go without taking out my house or anyone else.
That’s better. Ideally move them into a bucket or more of sand. I don’t know how it would work for batteries, but explosives get more dangerous when put in a container. Sand is better because it can absorb a lot of thermal energy without catching fire. Any non conductive non flammable material like that should work.
Also I’m not an expert on this stuff. Go find and listen to one.
Dry sand is important. Wet sand turns a metal fire into a metal fire fountain.
Well, it’s not sand exactly but I had a lot of spent casting silica on hand.
It’s basically a dirt filled metal ammo box under a pile of bricks. Even if it was unable to relieve pressure through the seals (no idea, but waterproof rarely is also airtight especially for internal pressure) I’m not concerned with an explosion. Although to be clear, the gasses produced by lithium can absolutely cause a sealed container to rupture.
The bricks are quite insulatory by themselves, the dirt was just so it could absorb moisture a bit better just in case, and if it all does explode, the weight of the bricks will keep it from hurting the garage door 30ft away. I don’t believe there is any danger of hitting the road with anything should the worst happen.
I keep wondering if there’s some specific condition that needs to happen for them to be dangerous. Once had an old phone that got all puffy and decided to test it by shooting it with a bb gun but got no reaction 🤔
Bulging and then charging is a fuck no as far as lithium batteries are concerned that’s the specific condition. Like many of the others said, it’s a huge fire hazard in that state.
The bulging battery on its own isn’t (much) more dangerous than a normal one. The problem is once the device splits open, the battery is no longer protected and much more likely to get accidentally punctured. A regular battery combusts when punctured, and the bulging battery would vent that gaseous content (which IIRC is Hydrogen) and then combusts, which makes for a larger initial fireball.
I used to deal with puffed batteries a lot and went through some basic training on safety and how to ship devices with them for repair. We only ever had one battery fire, it was a from a normal battery, and it happened when someone shoved a t-pin through the headphone jack of an iPod touch because they thought it was a reset pinhole.
