Is it safe to discharge a punctured battery?

I accidentally punctured my battery while opening ny macbook. It flamed for a fraction of a second but no heat. I took an appointment at Apple to replace the battery but I am tempted to try and turn on the machine. Is it safe to try and turn it on?

Is this a good question?

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

I really don't recommend powering on the machine as battery are nothing to mess with, if you power on the MacBook it will probably do nothing or catch on fire. Lithium fire are dangerous and extremely hard to put out.
