Yep, it looks like it made contact with the change, which happily became a low resistance path for electricity. Which, as you noticed, causes a LOT of heat.

It's good you caught it quickly. That could have started a fire. Er, more of one than it did.

The battery that was involved is toast at this point, of course. And I'd definitely get a battery case for your batteries. Your purse is as bad as my pockets, where a 9 volt decided to short with my keys. The keys were fine. The 9 volt was fine. I was not...

Purse, batteries, case a must.
I get these, cheap insurance. When carrying your PV in your purse , make sure there are no metal parts in near it also. If the zipper, or anything else contacts your PV with the battery inside this also can start a meltdown.

There's getting to be more and more of we ecig users, and more and more little powerfully explosive batteries in peoples care.

And around children.

And its not just us ecig users that are at risk.Most of the general public is completely oblivious to the fact that Li ion batteries in our cell phones, I pads, laptops etc. are potentially dangerous.
I never gave much thought about battery safety,myself until I educated myself about the dangers before i purchased my first apv.

I've posted this before in the main forums before, but because this is such an important safety issue, it deserves to be repeated when these topics appear.

I had been stealth vaping a mechanical BB mod at work. I would typically keep it in a pants pocket in my locker between vapes, between breaks. The BB has a protruding fire button, and when I put the mod into the pants pocket I was unaware that the fire button got compressed.

When I returned to my locker to have a vape, I felt the BB in the pocket and it was too hot to touch. I grabbed a wash cloth and pulled the mod from the pants pocket. The stench of vented gas was of melted plastic and electrical components. What I saw was melted plastic of the battery's body and both ends popped off.

Obviously, in hindsight what had happened was the battery became discharged too quickly because of the compressed power switch in the pants pocket. The battery went into thermal runaway.

There is no protective electronic cut off in a mechanical mod. The protection built into protected batteries might as well not even be built into them (IMHO). The only safety features the BB has are a hot spring and the fire button allowing gases to vent through it; the mod worked as it was designed to do. It was my error to not remove the battery between use, or detach the connection to the delivery device, or to not make the mistake of leaving the mod unattended where the fire button could be activated.

I would like to point out that the above battery was a so-called "protected" 14500. Since this incident, I no longer put my mods into a pants pocket unattended and practice more common sense with batteries. I no longer use protected batteries, preferring the safer chemistry IMR batteries.

This happen to me about a week ago. In a rush I drop my batts in my bag and about 40 minutes later my bag was smoking. At my granddaughters birthday party bunch of kids around me, I freaked. But I was near a door, ran our and
started pulling everything out until I got to those hot batts. Pulled them out, let them cool for about an hour, wrapped them up and took them home and tossed them. They were new to, I had drop them into my change purse in my bag. I should know better, I always have my batts in a case. I was rushing and not thinking, will never do that again. Glad everyone is ok!!!!!
