How to Dispose of a Lipo Battery? Does Salt Bath Really Work?
ฝัง

- Ever since I first started in RC, I have heard various ways folks have suggested to dispose of used lipo batteries.
One of the most popular, and the one I have used, is to let the battery soak in a salt bath. The theory is that it helps discharge the battery down to zero voltage so it is safe to dispose of.
BUT - I recently saw something online that said that might not be true. Well - only one way to find out. Truly test the theory and see what happens!

"Supposed to be 48hrs...I forgot for a month" lol good stuff!
Stuff happens... :)
That’s what I do as well . I pull them out when the batteries stop fizzing or bubbling even when moving around while submerged. Awesome and important video Troy!🙌🏽🔥🔋💨
Thanks!
Great info Troy. Always wondered if Home Depot would take them. Thanks for sharing this info. 👍👍
Very cool, thanks for the demo. 👍 I was doing some reading, the batteries we use are a lipo\lithium ion hybrid.
Interesting! Thanks!
@@RoadsideRC you're welcome!
Great demonstration and video i did this a couple weeks ago with a rtr battery that dropped a cell
Thanks!
Cool !
Like any other rc people I also end up throwing batteries away and I usually do the following. Use my charger to discharge, then I also built a discharging rig with a buck down to light up a led, then like you said, salty water, then last final stage is any supermarket or bus stop in Europe have battery recycling containers.
They usually go to specialized companies which by law and principle, since they get raw materials for free, then give part of their profits to NGOs, mostly handicapped, but not only. So it's both good for the environment AND for the people!
As always nice content.
Peace may the torque be with you
That is really interesting!!!
We don't have any such laws here in the US.
other parts of europe also got a system where its posible to leave used batteries in a container in regular grocery stores.
Good stuff! Wanted to do the same video recently too. And I see that Ridgerock back there! 2:32 !!
Yes!
I was happy to pull this off!
My buddy who works at our local recycling center and specifically deals with electronics told me cut the leads, and just throw them away. He said they cut the leads then send em to the scrap yard.. I discharge them as much as possible and put em in the garbage
Very interesting!!!
HES WRONG TOO !
you should NEVVVEEER just throw these away.
MUNICIPAL RECYCLING SERVICES ARE NOT THE PLACE TO TAKE THEM EITHER,for the most part anyways.
Take them to a legit recycling place for batteries.
Thank you! I have two to do same thing
Glad it works!
I like this controversy 😁 Personally I still use this method to drain cells, I would also shoot the batt just to make sure no fire would happen. Nothing would happen🤟
Great vid!
Thanks!
would be nice to hear from the recykler if they whant us to soak the cells or not depending on if that destroy the reusable material?
I agree 100%!!!
I had a deeply discharged 3S lipo (there wasn't any cutoff mechanism in my DIY car) and tried to charge it (what a stupid idea) so I ended up with two working cells and a dead one giving 7mV. Can I safely just take it to a battery recycler and use the other two as a 2S?
Hmm. There is a lot involved in the answer here.
Basic answer: don't mess with compromised lipos. They do legitimately pose a fire risk.
A new battery is much cheaper than repairing any fire damage.
Great video 👍 Salt water trick absolutely works. I prefer using an automotive lightbulb to drain my batteries, then I drive a nail through them to make sure they are dead. Much cleaner and faster.
That would really be cleaner.
I hope they are all fully dead before you use the nail!!!!
Lol using the nail is pretty extreme, especially if it's not actually dead.
I just posted a video on this exact method. I've done it this way for a long time. But a viewer pointed out to me that this way may have some problems, that could cause even more problems. I read up on it, and was convinced enough that I took my video down, which hurt to do so because my channel is very new so I could use the views. But, I also want to be careful what I pass on. Your video seems to show it's a safe method as I always believed it to be, but the literature I read was just convincing enough that I took my video down until I learn more. But again, you seem to have effectively drained those batteries perfectly. So now I'm just confused lol.
Interesting!
I also had heard some conflicting info, after years of doing it this way. That is exactly why I did this video.
@@RoadsideRC yeah it's one of those odd things where I know it works, you obviously proved it here as well, but there just enough conflicting information to make me wonder otherwise. Maybe it's more of a case to case kind of thing. Maybe some batteries react badly while others discharge perfectly.
Wow, just did this and it’s super easy, I would much rather this than set it on fire as the fumes could be very bad to anyone that breaths them.
Great job 😮
Glad to help!
Great Video Troy kinda reminds me of the show Myth Busters 💯 Good information in the description too

Thanks Larry!
What do you do with the water at the end?
Just dump it in the grass.
Make Kool aid...🤪
In my case I use cheap esc for discharge, connect the lipo and put the esc and lipo safe place and put esc on monitor the lipo voltage, is really safe, I use a nail no fire once the reader voltage don't detect voltage is safe, this method is safe, I think the salt is great drainer of voltage, because is under the water if catch fire the water do the rest
Interesting - thanks!
I'm trying to find a way to get my used lipos to Tesla, upvoted!!!
Interesting idea!
I have old one outside till I figure where I can go
So the tab dissolved and that started at storage. So it's probable that a fully charged or higher capacity pack would have dissolved it before it was fully flat.
Maybe!
I usually soak it for a week then shoot it a few times with my pellet gun to make sure nothing explodes then i toss it.
That would do the trick!
I would be more convinced if you took it outside and put an axe through the side and nothing significant happened. Case rupture is usually the scary thing with lipos.
I put a nail through it...an axe would really be different?
Put a resistor across them for a couple days don't put them in fully charged
That should work also!
I really wanted to see some fire hahahaa
I thought we might see some!
Why would anyone presume discharging the battery makes the chemical composition safe ? AND if you ARE going to take them to the recycler, WHY discharge them in the first place ?
This is the method suggested by many of the top battery manufacturers.
Less energy = less energy - so discharging is logical.
My local recycler dumps all of the batteries in a huge bin. Less risk of anything happening with the battery discharged.
I Wanted Fire 🔥🚒🔥
...I kind of did as well... :)
Id rather make a fire! 🤣
Sure is more exciting that way!
But then, you can't recycle them.
It looks like a cheap multimeter good multimeters don't do that
It was rather cheap, and is very OLD.
As a trash man they will light up a trash truck even with ends cut off and discharged
Woah! Thanks for the info. Glad I drop mine at the recycling center.
When that happens - what do you do??
@RoadsideRC welll hahahahah if the fire is in the hopper we dump just the hopper on the street and if small enough put it out and find the batteries if inside the truck well whole truck gets dumped and the fire department gets called
@@johnsupplee9053 Oh man! That could get really exciting...in a bad way.
Does it happen often?
@RoadsideRC not often but it happens most of the times it's people throwing away kids toys or there old laptops that do it but rc battery's are a issue cause there small and hard to see
the idea of mixing lithium and water is not a good one. I really prefer the battery getting crushed by the dump truck
You might cause a fire! Be careful!
Thats a good way to make explosion
I've taken a few and dropped a rock on them to see what happens, they just fizz and smoke alot. I've also seen a lipo battery charged in nimh to try and fix it and he did it to long, produced a 3 ft wide flamed explosion.
I really hope I don't have one of those explosions in my garage some day.
