safety - How dangerous are disconnected bulging batteries?


It is well understood that if you have a device that uses a Lithium-Ion battery, and if the battery starts to bulge, then something is wrong with the battery and you should properly dispose of it by taking it to a battery disposal/recycling center. Improper handling could result in a fire being started by the faulty battery, so it's best to dispose of the device and have it replaced.



However, I am curious when the battery begins to deteriorate and starts to bulge, is it still dangerous when it's removed from the device and set aside? To be clear, none of the metal leads are coming in contact with any metallic, or conductive material, so the circuit is not complete on the battery. It's just sitting on a non-conductive, safe surface.


Context


I bought a piece of hardware yesterday at its only problem is that the battery is bulging. I've taken out the battery and I want to keep it until I can find an OEM replacement, which could take a few weeks to arrive from the distributor.


I want to keep the old battery so that I can compare it against the replacement which, I'm afraid, might be a KIRFy piece of hardware. I'd want to return it and get a refund if that were the case. Keeping the old battery around for a while does have it's purpose.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
