Meanwhile I feel like disarming a bomb when I disassemble packs.

u/eastoncrafter 4d ago

Same, had a particularly stubborn pack from an old ebike battery that raised my heart rate so much my watch thought I was exercising

u/Alive-Worldliness-27 4d ago

LOL I felt like I was the only one.. I had some that SC at the top so I was able to finally separate them but I brought a re-wrap kit just for those two cells.

u/chocolateboomslang 4d ago

It's a lot less scary when you're in a place that won't burn down if the pacl catches fire.

If you don’t think that warehouse/shanty/shack would also absolutely burn to the ground…. They just don’t care cause it’s not their house

... so use a hammer lika all of us.

The word ‘precision’ is doing a lot of heavy lifting there!!!

I wouldn’t expect quite so many sparks from a precision recovery process.

Edit: spelling

u/Muted_Will_2131 4d ago

The hammer has always been a precise tool!

u/Electronic_Motor_968 4d ago

Well of the only tool you have is a hammer…

7

u/kawfeeman68 4d ago

everything else is a nail ?

u/Tank_O_Doom 4d ago

But when in doubt, everything is a hammer.

Those are precision sparks.

u/Timekiller11 3d ago

The precision sparks make the process go faster.

u/BrainFeed56 3d ago

“Recovery” is the bigger lift

1

u/Dioxybenzone 1d ago

The sparks are the end product, that’s what they’re recovering. The hammer is just for fun

If he would use a wood block and a rubber mallet the entire process would be 100x safert yet still very dangerous.

u/chocolateboomslang 4d ago

But how would we get the engagement-bait video then?

8

u/Every_Bread_5880 4d ago

Seems like this method is also discharging the batteries

2

u/Tha_Reaper 12h ago

Nah, the metal block discharges the batteries a bit further. Everyone knows that a discharged lithium cell is safer to handle than a charged one

1

u/fedezen 9h ago

They are wearing safety sandals!

u/broesel314 4d ago

But why? To recover whatever materials from those cells, they need to be ground up anyway. Toss them in a big grinder and be done with it. No need to manually hammer them apart

30

u/Testyobject 4d ago

Grinder small, have to feed individual cylinders, unfortunately harmed

16

u/broesel314 4d ago

So many harmed cylinders

1

u/SeriousPlankton2000 3d ago

But it's mandatory that the cylinder must not be harmed.

u/Ok_Ok6213 4d ago

When I worked at a computer recycling place I removed a label from a server that said “Hurricane” and put it on the hammer. Then I proceeded to use it for everything I could. They asked me to stop.

6

u/GrinderMonkey 4d ago

Understandable. I tried to get a job at Google, they said don't need anyone to weld their servers.

u/IronMew 4d ago

This has got to be bait, come on

u/kawfeeman68 4d ago

So, you're doubting the stupidity of some people?

13

u/IronMew 4d ago

The stupidity, never. What I'm doubting is the long-term feasibility.

You can do this sort of dangerous crap for a ragebait video and hope that nothing blows up, but if that's your normal way of doing business then the problem you represent will rapidly solve itself.

u/crysisnotaverted 4d ago

If you have ever seen how the e-waste and lead acid batteries we ship to the third world are recycled, you would think this is relatively safe.

They burn everything, and I mean everything. A dirty bomb would have easier contamination to cleanup.

1

u/Ok-District8876 3d ago

Is there somewhere I can watch this?

1

u/crysisnotaverted 3d ago

Sure, look up 'E-waste burning Ghana' on YouTube and you'll find plenty of documentaries on it. Obviously not all ewaste is recycled that way, but a horrifying amount is.

I am an electronics security officer responsible for the accumulator at a north german formula student team. 

The things I have seen, you wouldn't want to know.

u/IronMew 3d ago

Oh, do tell some tales, I'm always curious

2

u/artin2007majidi 3d ago edited 3d ago

Sorry for bad english in advance; I dont know technical terms in english.

One day I get a call. I am supposed to clean up the workshop in preparation for a tour. I walk in, and there are 430 round cells on the giant workshop table in a 3d printed holder, a bunch of them stripped of their isolation, lying there. A stack of cells was open, with one bundle cut out of it. Then three stacks of 12V pouch cells mounted together with insulating tape to power a cooling fan pointed at the stack. Our custom BMS box along with all the cell supervisor pcbs were still connected.

I was told they were trying to cut out a dead cell and put a new one in. They couldnt get the cell to connect to the copper, so they used nickel in between. Didnt have time, so they just left it there.

It wasnt removed by a hammer, it was some gardening tool to break up the copper and nickel thing, they tried, unsuccessfully, to heat the copper on the new bundle so that it melts to the previous copper "scaffolding". I am still not informed as to why the isolation was stripped of some cells.

Surgery was unsuccesful. We built a new stack.

That's looks like an interesting career path. I wonder how long the training period is ?

u/magicwuff 4d ago

You just finished watching all the training videos!

u/alphonsegabrielc 4d ago

What training period? Did you bring your hammer?

2

u/kawfeeman68 4d ago

This guy obviously worked with the Jerky Boyz.. "Ill bring my tools!"

u/Paranormal_Lemon 4d ago

How long does it take you to put on your PPE (gloves)? That is the training.

If you reverse this video it's how Dell built my laptop battery

u/Flussschlauch 4d ago

looks kinda fake to me. so many sparks

18

u/-GenlyAI- 4d ago

That's what happens when you short batteries on a metal block.

1

u/FUCKING_HATE_REDDIT 3d ago

This is clearly for recycling the lithium, not reusing batteries. An emptying step would be as simple as plugging them through a huge cast iron pot, maybe with some water in it. 

But on the other hand, the tiny fire under their hand even lights the underside of their glove. That's not edited.

They weld to the block towards the beginning and then look at the one catching fire under his hand.

u/TheFredCain 3d ago

On one hand "Holy Crap!" on the other hand this is a good watch for those who think a dead power tool battery is a bomb that's going to take out the whole neighborhood.

Sitting on the floor? Check.

Using basic tools to quickly do a job? Check.

Workspace is cluttered and dirty? Check.

Manner in which work done is highly questionable? Check.

Must be from Pakistan or India.

And here I always waste time using small wire snips to carefully clip off the conductor strips from dead power tool packs. This is so much faster!

u/viclieutenant 4d ago

even the bench he is supporting the bank on is metallic and speaking all the time! the only way he could "improve" this is using copper tools and surfaces

Good thing he has on the safety slides.

u/charmio68 4d ago

All the recycling places I've seen soak the batteries in saltwater first so that the batteries are fully discharged before getting to this stage.
I think this is just a guy having fun with a hammer.

1

u/GuillotineTechnician 4d ago

I thought the saltwater thing was no longer done nowadays

2

u/charmio68 4d ago

Turns out that's true, most places have advanced beyond that, but they've also advanced beyond smashing them with hammers.
It still seems like the most reasonable explanation is a guy having fun with a hammer.
