Hi!

Im working on a project to disassemble this crappy cheap bt speaker and mount it i side an old phone. But ive encountered a problem. Many parts are glued stuck. The battery for example. I dont want to use violence to remove it because it could be damage leading to a nuclear explosion. Any advise in how to proceed?

Heat gun, careful slow movements with a dremmel, or soldering iron to melt the plastic away. That motherboard can probably handle a flathead screwdriver as a wedge to unglue without snapping apart, though I appreciate your carefulness in avoiding a nuclear Holocaust.

The battery won't explode from a heat gun? Ah, found one that goes from 50-600 degrees celsius, so at the lowest setting maybe?
Also, i forgot to mention, the battery is glued on on the back as well. ๐Ÿ˜ซ
But I could probably get a better angle if I like cut of a piece of the plastic that it's stuck to.

If you have access to a heat gun, I'd give it a shot, especially because the battery needs to be removed too. My other suggestions are not the best for removing a battery, though you might be able to get a good angle to wedge the battery off without stretching the components in the battery.

Consider draining the speaker battery first. I wouldn't bother, but if you are really worried about breaking the thing it's worth a shot.

I've taken apart many consumer electronics in my day, and (anecdotally) batteries have not been an issue. I'd say that you are more likely to snap a wire off one of the components or something quite mundane.

Thank you, good sir, ill get a heat gun today. I have a feeling ill need ut for more future projects :)

A lithium ion battery can safely take up to 60C or 140F. https://www.eblofficial.com/blogs/battery-101/lithium-ion-battery-temperature-range
I'm sure that'll melt most glue.

If you're not planning on ever using it again, I'm sure it can take a bit more heat for a little while, but my quick search could not find the specifics
