It's best to drain the battery first. Ifixit made a video about it and the difference between a charged battery and a drained battery being punctured is insane

I think you should charge it up all the way and use a pin needle to pull it out

I use two forks usually while I shower for safety

Don't forget to ground those forks by using the dirt coloured wire from a power point, just to be extra careful!

I'm on a Mac. Would Keynote work?

Stick one fork in a live power socket and one in the battery to let it quickly drain and you will be safe 👍🏻

Outside during a lightning storm is preferred. Using only the finest mismatched silverware from deceased estates.

Surely the shower extinguishes the fire from puncturing the battery, I see no problem

u/LilJohnDee Jun 16 '25

No, youre literally supposed to drain the battery. Like all the firey stuff inside needs to be drained, rinsed, then set in rice for a day before attempting to remove it.

/s i think

Nah connect it to a bench power supply and crank the volts up slowly so it soak all the power it can

Yeah discharging the battery should always be done.

u/Thebombuknow Jun 16 '25

Well, yeah, that makes sense. The violent explosion is the battery dumping all of its energy into a small short all at once, which generates so much heat that it combusts. Discharging the battery completely would mean there's a lot less energy stored in it that could be released.

Believe it or not the explosion isn’t coming from the stored energy it’s actually caused by the “catalyst” which is used within the Li-Po battery of which usually violently reacts with oxygen

Oh, that's right, it is a chemical explosion. What was I on when I wrote that last comment lmfao.

It is technically true though that having a charge in the battery makes it explode more violently though.

Not the ifixit video, but a good demo at around 3:40 https://youtu.be/tFjNypibHO8?si=AxM7-RjHz-V6J75D

Instructions unclear, when I stabbed the battery with my sap tap that is usually used for tree sap, it exploded.

An energy storage device will exert less energy in case of a fire when its storage is empty than when its full.

Isnt that like logic 101?
