IMR 18650 just went hot, ouch that burns!

[Bullwinkle]

Was just playing around with my new P+ and surge tank with 18650 AW IMR. The button stuck and things got hot, real fast!

Fortunately I was able to unscrew the lid and break contact, but I think I'm going to be holding an icepack for a while.


Think the battery is toast? Never had a thermal event with one of these before.

Glad this didn't get any worse for you. As for the battery I'm clueless on how safe or unsafe to use again.

The battery may be fine, but the conventional wisdom is to toss it right now.

Please do not use the battery again, it is just not worth it. The odds are that it will be fine, no issue ever. The cost for a new one? what $10 from or so from orbtronic? The cost if it goes thermal and you cant get the connection broke fast enough? potentially much much higher. Personally I would view it as the battery warning you, and I recommend you listen to it. All just my opinion, but truly it is what I would do in the same situation.

If the battery overheated, I would definitely toss that one. That's too big a battery to be playing around with if something goes wrong. If it was only the tank that got hot, the battery is probably OK. If that battery did get hot, it was surely more than just a stuck button; that coil should not be drawing so much current that it causes your battery to overheat. Overheated batteries is probably due to a short somewhere. I would fix a short before I stuck another battery in.

I wouldn't re-use a battery that had gone thermal.

 

[Bullwinkle]

It wasn't the stuck switch that caused it. The switch stuck when it started going thermal.

I know what happened, it was an adapter I had on so the center post on the surge tank wouldn't scratch the hell out of my P+'s atomizer contact. Must have caused a short.

I will toss it for sure. Unbelievable how hot it got in a fraction of a second.

Had a shorted atty on my VMod.

Searingly hot instantly. The Hot Spring did it's job and collapsed but it left me with a huge amount of respect for these battery's we use every day.

Was quite blase about battery's until then, now I treat them with kid gloves.

When in doubt always toss the battery. " Thought it would be ok" wont help any if that battery has been damaged and you arent lucky enough to stop a major venting from happening.

Keep an eye on epipemods.com in the next couple of weeks. They are coming out with a drop in fuse for 18mm tube mods. A short like a stuck button would have tripped the fuse before letting the battery get hot.

Nope!
The fuse will protect against the short that he caused with the extension, but it will not protect against a stuck button. With a stuck button there is still the resistance of the atty/carto allowing it to continue to fire until the atty/carto fries.

Like that bug, is it a 62?

So would a hot spring solve all of the issues?
And if not, why not?

In other words, I don't know squat about how all this works, and why sometimes it doesn't work.
I had to Google "battery short" just to know what that was.

I would think that a hot spring would solve all problems, but if it was that easy then I'm sure that would be the simple fix.
Clearly, since I have not seen anybody recommend it as the simple fix, there must be a lot I am missing.

I have no problem admitting that I don't know anything about anything when it comes to this stuff.
And yes, I minored in physics a long, long time ago.

Yes. You are right. It wouldn't act as a cut off, just a fuse for a short. I was thinking about Andy Thatchers post while typing about Bullwinkles post, I guess.

It's a '65. That's the 'before' picture. In the next 45-70 days, I hope to replace it with an 'after' picture. Paint is done, interior is almost done, mechanical is almost done, -- just a few trim details left and waiting on a part or two.

Hot spring is about like a fuse. So, in this case, it might not have have helped. If the event would have gone on a little longer, a hotspring might have collapsed... but maybe not. If there had been a short, it would have overheated a hotspring really fast and it would have collapsed.
