Is it safe to discharge a punctured battery?

Hi

Consider this a extension of the great answer that @fpfp has provided

As @fpfp has said lithium battery’s or just battery’s in general are very very dangerous so here’s what I would do

I recommend leaving it in a safe place where nothing can catch fire for 24-48hours to let the battery somewhat stabilise as once something like this happens anything can happen from here going on

I would take it to a authorised repair shop to have the battery removed safely and replace it with a high quality one that way you can better protect your device from damage:-)

If you have any questions please ask

Hopefully this helps

Thanks:-)
