At 2.5V itâs already dead.
Thereâs only a tiny bit of energy left in the cells at that voltage. You can just tape the connections or tabs well, to prevent a short circuit, and recycle the pack.
If you really wanted to you can discharge each cell individually to zero volts but itâs not needed.
DO NOT TRY TO DISCHARGE A LIPO PACK TO ZERO VOLTS!
If the cells are not balanced at those low voltages (theyâre not) then you can easily drive one cell to below zero volts. If you continue to discharge the pack then that cell is now essentially being charged in reverse and that can lead to a fire and or bursting of the cell.
There is a stunning amount of bad and even dangerous info out there about LiPoâs.
What did they say the puncturing did to help? I canât imaging how they could think that releasing toxic organic solvents and lithium salts would be helpful or how possibly short circuiting cells that might not have been completely discharged would help.
Even if the cells werenât shorted and no electrolyte leaked out, how can they say puncturing helps versus just discharging and taping the pack up? I am definitely confused.
All I did was use a bulb for about 30 seconds (only amount of time it stayed lit) checked it with the mulitmeter, (still 7v) and then threw it in salt water with the leads cut offâŠ
I donât even remember, I have never done this to a cell but I thought it was on some recycling thing. Forget it anyway lol your way sounds less dangerous in the first place
How did this salt water thing ever get started?
Never, ever use this method.
We donât need to discharge the packs in the first place. Just tape them up.
Salt water discharging is incredibly slow and causes electrolysis destruction of the tabs, exposing the inside of the cells and creating toxic sludge water if you let it go far enough, and never fully discharges the cells anyway. If the tabs are gone we have no way of confirming that the cells are discharged either.
Itâs just not needed.
I accept that itâs a very popular bit of advice for many web sites but theyâre all just repeating something they have heard about from somewhere else. Here are my tests for round cells, where the metal is a lot thicker than what LiPoâs use:
I think thatâs what Samsung, Murata, and LG recommends. Shotguns work well too.

ummâŠjust kidding folks (because thereâs always someone who believes me when I say stuff like this).
This is so weird. I just asked Molicel what I should do with my old cells and they said âjuggling practice.â Its crazy how different products need such different disposal methods!
Fogstar hasnât got 30 and 50mmâŠ
I sent a request to nkon, they will stock wide nickel soon
(okay not so soon, they told me 12 weeks before you can order it xD)
Also nkon is a tad cheaper for me (especially cells) because no import tax from GB
