Hypothetical question, if a loose battery in the pocket entered thermal runaway, could it cause one or more cells inside the mod, that is also in the same pocket, to enter thermal runaway?
Yes.

Easily.

And if the batteries are positioned right, possibly instantly.

We DO see loose cells. And vented cells.
Ray Charles could see this person had no idea how to use their gear safely.

The evidence is clear.

No imaginary scenario will change that.
How come Stevie Wonder never gets credit?

It's always Ray Charles that could see things.

It must be a conspiracy!

Gas permeates nearly everything.

Hot gas just does it faster.

Again, it's the heat that would trigger the secondary reaction in this case.

Or melting a wrap resulting in a short.

In the case of the wife's kanger subox mini kit for example, the battery door has vents cut into it in the shape of the kanger symbol in the negative image of the slits.

Or it could be knocked completely off in the pocket.

Either way, if the gases of a battery were venting into those slots, it would all but be a done deal for the battery in the mod.

Other mods obviously would have the same potential to varying degrees.

Okay, makes sense. I guess the reason I have trouble comprehending is because I've never witnessed something like this in person or video - the *instantaneous* venting from a short or trauma. Not saying I doubt it for a minute though.

Incorrect, sir.

Batteries aside from lead acid batteries can easily short within themselves.

Could be a manufacturers defect, <ETA>crystalization of old or abused electrolyte </ETA>, an impact or a weight or force that creates an internal disfigurement in the cell.

To add to that, the cell doesn't have to short to go into thermal runaway.

Thermal runaway is a thermo-chemical reaction that in a lithium battery is caused by either A) excessive heat or B) exposure of the electrolyte to oxygen.

So a welder for example could have some slag hit his pocket and not know it until his battery is venting.

Or any scenario that includes impact, puncture or force upon the cell could be a likely cause.

Yes, batteries do have a small failure rates. Mods have failure rates as well. This is true.
A couple of points.

First, this is one of the reasons why I don't go along with the assumption that virtually all venting accidents "must" be user error. (I'm not sure if you said that, but others have)

Second, do you really think that a little plastic box is going to do anything to protect you if a battery went into spontaneous thermal runaway or stop damage from heat, impact, puncture or force?

Well.

Since actually none of your post pertains to what you're quoting...

I'll go with something that does and hopefully find some middle ground.

I HAVE actually shattered a couple of those plastic cases.

And it IS possible that having them in my pocket might have saved my rear.

Let me know if you require a lengthy explanation.

It's not conclusive proof of cause, that's what I'm arguing. I'm not arguing that the loose batteries are safe practice.
Then say that so we can agree that keeping a pocket full of loose batteries, change and metal mods are indeed user error.

Then I can say that forensically that's not 100% undeniable proof of cause.

Ya......because it wouldnt be in my POCKET in the first place!!
I like to keep my boys away from them.

The fact that they are loose only multiplies the danger and risk.

Store batteries in a case and keep them away from your crotch.

Pockets are a really bad place for mods and high-discharge cells.

Right.
That post was in reference to someone assuming that keeping 1 battery in their pocket alone can't result in mishap.

When you quoted it, you didn't address that at all.

You inferred that I didn't know the limits of a plastic case.

And you made a poor case of it.

Your argument didn't allow for a shallow puncture, a near miss or a rough glancing blow that otherwise would peel back an insulator and short the cell at the + end.

Just to name a few.

I've seen what you said repeatedly... and I've seen you try to hammer me for saying that loose batteries in the pocket is a user error.

I'm just glad that's out of the way. :blink:

Agreed.

But I run out of hands sometimes.

Shrug... it's never for long, really.

You're probably right that pockets next to the family jewels are not the best place to keep high-drain batteries. That being said, the failure rates are so low, you have a better chance of getting hit my lightning.

Speaking of lightning and warnings, years ago they added a warning sign to the metal building on the top of Mount Whitney because a group of Boy Scots decided it would be a good idea to take shelter there during a lightning storm. The results were not good.

burnie, personally i think you're nuts... carrying a loose battery, even by itself in your pocket.

no one plans to have an accident, but a good impact(yes i know it's hypothetical)... say crossing a street and clipped by a car... if the battery is in a leg or shirt pocket and gets hit by the impact? yes it can be damaged enough to and such. we cannot say we need to educate and then have a member who seems well educated in proper vape use... saying "naw this is safe, been doing it forever!". it's a great example of do as i say not as i do. we need consistency and agreement on the safe way to do things, for education of new vapers and to stop things like the OP being used against us.

no matter how you look at it, there was some user error involved, he had at least 3 loose batteries in his pocket with the mod, even if we don't know %100 the chicken or the egg.

Dont get it wrong...
Im all for knowledgeable adults that are careless with tools to have the right to ignore all the information available, and shove high dischage cells in their pants if they so choose.
Nature's way of protecting the gene pool.

Just take responsibility for the action and stop blaming others for not holding your hand.

I don't assume that batteries can't fail on their own, but I do think a little plastic box would be little protection from a force that's capable of blowing a metal mod apart. I will coincide that a battery box might prevent "some" damage, but if you're really concerned about it and work/play in an environment where you're likely to damage a battery, some sort of case that has more impact resistance might be wise.

I've not hammered anyone for being against the practice keeping loose batteries in their pocket. I've only spoke out against jumping to conclusions about cause, without all the facts.

Who in their right mind would use one specifically for that reason?

They're supposed to AID IN preventing those forces, NOT stop them.
