Off to the snickers wrapper they go then 
You could send it to the guy who posted on here yesterday about how to disassemble a li ion cell, he already cut the top off one, he is a graduate student or something.
+1 Very well Said.
Send it to me :P
I think if you tested it at zero voltage it's a door stop why does anyone freak out about a dead cell .unless he went back and edited his post .
It says he tested it at zero volts ..That doesn't scare me ..Should it ? check voltage and if it's dead or very dang dead ..Wrap them separately in little plastic tape them up and recycle them . killer gases comes from the batteries on fire not sitting there doa with no voltage . i ain't scared
If i saw a battery bubbling ... it might get my attention
if I'm wrong ....i'd like to know
Tell me Cat eyes, you use “LSD” Cells to keep you going, don’t you. Just curious, do you insert them Nasally, Intravenously or Rectally. 
just because theres no voltage doesn’t mean everything inside is in its lowest energy state, it just means the chemical reaction isn’t producing electricity, i don’t know much about lithium battery construction, but if there are chemicals that are reactive then you could have a problem, say acids, hydrogen, pure oxygen, materials incompatible with water, air, calcium, magnesium etc.
Hydrofluoric acid is a good example, i’m not getting into the debate of if its in batteries or not, but its an example of something that may not produce electricity, but is still harmful no matter if its sourced from batteries or aluminium etching solutions.
Plutonium is also a good example, I’m not getting into the debate of if it’s in batteries or not, but it’s an example of something that may not produce electricity, but is still harmful ….
CPF meh, they’re drama queens any way…
Awww, now where’s the fun in doing it safely… just boldly go! J)
It’s prolly a bit hard to do that as every pack is slightly different, plus I wouldn’t really call my method ‘safe’ as essentially I’m using a large blunt flathead screwdriver to pry the cases open using excessive force combined with a light careful touch if that makes sense…
DON’T use a knife to try and run around the seam!!! I have seen several packs where people have tried this and they have actually ended up almost cutting through the actual cells (can show you pics of this if you like as I had some in this batch)
One thing I would suggest though is starting in the area the battery connector is, it’s the weakest point to get it started, plus there’s less risk you’ll accidently go through the casing initially and stab a cell :~ Once you have a leverage opening then slowly (and carefully) work your way around the pack until you can pull the two halves apart. I work around cracking the case open by twisting the screwdriver head, bit by bit.
Once you have it open the cells are normally stuck to the bottom half with double sided tape, I use a plastic ipod opening tool that has no sharp edges to gently work under the cells to lift them, once unstuck the cells and circuit board lift right out.
Then cut away the circuit board (one wire/connection at a time) while being careful not to short the pliers against anything else on the board/battery contacts.
I would suggest you wear eye protection and do this outside given my recent experience lol……
If it’s an HP pack, some of these seem to be plastic welded, with a strip that runs around the side the connector is on, these are really hard to open.
How do you dispose of damaged cells?
My local council has a battery recycle bin at their offices, put there by batteryworld.
battery recycle bin ?? Whee !!!
Then that's where i'd be pulling laptop packs from and donating all the old really junk cells ..if they start to give you any flack about it just ask them what the definition of recycling really means ..is it just finding a different landfill for something or is reusing a battery that still has value the smarter thing to be doing .......gets them everytime because you're right .
Better yet get the guy who works there to save you 4 or 5 packs a week . after about 15 packs you're pretty set for life and will be tossing batteries most people here would be saving . It's nice to have a little cache of lithium ion charged and ready to go .
When people are discussing not fully charging up cells to lengthen their life time you'll smile and shake your head thinking.." having 50 fully charged 18650's that you paid nothing for isn't such a bad idea ...
"I see a bright future in store for you"
Lithium Ion cells are not classed as hazardous waste - they are permitted in landfill, but can (and should) be recycled.
It has been rewarding to check…
Kick it into the grass and forget about it.
Until the first mowing.
I have an ex-wife that falls into that category. Something to do with chemistry, or hormones or something……never produced a damn thing but harmful as all get out.
I hear ya, did you get the right to remain silent to
It will chemically neutralize it.
Ever tried external snap ring pliers?
Get an opening started big enough to wedge the tips in, then squeeze. It pops open. Move the pliers a little further along and squeeze again, more pops open. No cutting/sawing/poking.
