<p>Very few details...What does it mean "he opened it up" I would
even know how to do that with the L-ions I've been around, seems
like its something a manufacturer should be doing. Temperature?
charge rate? recent usage history? Age? Was it disconnected? Did
contacts touch a conductor?........</p>
<p> You can probably get water to explode if you abuse it
just right.<br>

The battery wasn\u2019t working, 5v.
He opened it up and it exploded when he opened it. The lid hit the roof.
Fortunately no one was injured.
Anyone know what to do with this? IE recycling?
And just another example of non explosive lithium batteries exploding
