Urgent help with disposal of LiPo cells that are swollen

[jo90]

Hiya

Hope someone can shed light on this for me. I have 2 IP LiPos that are now both very swollen, one case cracked open. I had discharged them to as lower voltage as they will go, and now seem to have swollen up like mad.

Firstly I guess I need to how to neutralise the cells so they wont blow and secondly where i can actually take them to dispose of them ?

If anyone has the right info I really would be gratefull for your help

Cheers

Drop them in a bucket of very salty water,when they stop fizzing in a couple of days,you can pop them in the landfill bin.

Lipos in water.... I don't know if thats a good idea

Not sure if salt water would make any difference.

Id take them to your local recycling centre. They will take them off you.

Never over discharge your LIPOS that the main reason the swell.

1/2 cup of salt per gallon of water.

You Must Discharge as per Thunderpower!!!!
I think 2 weeks is excessive though if they are low voltage already just leave for a night or 2 in a bucket of salt water!
Never take to landfill unless fully discharged as they could start a fire!!!!!

Literally the worst advice about Lipos I've ever seen...

Salty water - 1 month - Council dump box.

Dont pierce it, even when its fully discharged, Lithium and air dont mix too well...

They are in a very salty bath right now anyway. Discharged them to remove as much voltage as possible before doing so monitoring for any further swelling. They where old lipo cells, so it wont hurt they are gone

Normally i never discharge the cells, unless they are charged full and dont get used, then its only a half discharge.

These ones just had had enough, only about 2 years old. My older Demon cells (about 5 years now) are still going strong.

I did say, "Not Sure"... jEEEZE!

I saw a LIPO get wet in a boat once, Flames the lot... Lithium & water is not normally a good idea...
