I have a 18650 out on my drive that is bubbling, what should I do with it!???

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 ….

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.

hey how about you doing a video on how to safely open battery packs… i would like to see that before attempting to open the packs i have been collecting from recycling bins…

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.

Ever tried external snap ring pliers?

[comfychair]

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.

[comfychair]

These have angled serrated faces, not the round pins you get with internal/external c-clip or snap ring pliers. It's technically for 'external retaining rings' but everybody uses these names interchangeably so it can be tricky to find the right kind. Most common use is in transmission rebuilding.

Why not just fill a plastic coke bottle with water and put the cell inside?

i saw someone say that the battery contains acid …. acid and water do not mix well….
i think water mixed with the chemicals inside can cause an explosion and / or fire….
if the battery is not bubbling or compromised then salt water is safe for reducing voltage….

others know more than me… i saw this stuff on the forum somewhere

Water dilutes acid. ie makes it weaker.

No.

No.

i have heard about this…???
in a vent and flame event, are acidic fumes given off

and also , water added to acid does not dilute the acid…
i think it will explode….

you can add acid to water but not the other way around…

Well, you heard wrong.

You could get some fumes if the electrolyte burns… which is hard to do under water.

Problems mixing acid and water is a function of the strength and amount of the acid and the amount of water. Vinegar and lemon juice are acids. You can pour water in them just fine. Also, you can add water to a car battery, which has a rather strong acid in it.

Wrong. I have a degree in chemistry. I could have told you you’re wrong when I was still at high school.

Now if you add water to elemental lithium you’ll see something…

@cat eyes

ok so putting it in water is the correct thing to do it seems….

thank you for the help and info….

and are you saying that a burning battery can put out acidic fumes….???
what exactly does a burning vent and flame put out ???

Anything that burns can put out acidic fumes. Most lithium battery electrolytes contain fluorine which can make hydrofluoric acid fumes… not good to breathe.

Depends on the battery chemistry but it will be some gas like hydrogen fluoride (very bad) perhaps.

I dont know if putting it in water is the best thing to do, I just wanted to hear what happens when you do. But the vented gas should ionise in the water producing an acidic solution.
