So this just happened about 15 minutes ago. I had just taken my Sony VTC 4 18650 battery (purchased from vapor DNA) out of my 2014 Nitecore intellicharger i2. It was reading a little over 3.7, like around 3.74 - 3.76 Volts on my multimeter. The battery charger light display showed that the battery was only half way charged when I took it out, which I thought was odd because I thought this batteries max voltage was 3.7 (I'm not the most educated on how battery voltage works) Anyway I continued to put the battery in my SMPL mechanical mod clone. Now when inserting the battery, my mech mod didn't have a tank on it, but it did have an ego to 510 converter inserted in without the tank on. So as I put the battery in and was screwing the bottom copper piece on my mech mod, I noticed that the copper piece didn't stop as it normally would when twisting it into the threading, so it went in further than normal and (i think) caused the battery to touch the end of the ego to 510 converter. So as I noticed the copper piece going in further than usual, I heard a hiss noise for about 2 seconds. This scared the ....ing hair off my balls because I didn't want my fingers blown off and my house possibly torched. So I removed the battery as fast as I could and inspected it quickly. I didn't notice anything unusual. Then I dropped the battery... and picked it up then inspected it again. Now I noticed 2 pin point sized holes on the negative side of the battery. I looked closely and noticed liquid coming out of these holes. That freaked the .... out of me because I assumed it was battery acid. So I took the battery and threw it out into the snow and haven't looked at it since. I'll be checking on the battery's status tomorrow morning and maybe post some pictures if the aftermath is interesting enough. SO... what do you think is the cause of my mishap. Oh and one more note, I noticed no unusual overheating of the battery while handling it.
Sony VTC 4 Leaking Battery Acid?

3.7v batteries charge to 4.2 usually. Were the two holes roughly where the corner of the charger contact would be? I've seen a charger short out and leave two burn marks on the negative side of a battery, but never seen one leave holes...
Jeez - a SMPL and a 510 to eGo adapter.??? 
If the battery and mod got really hot - you dead shorted the thing and caused the battery to vent.
If the battery and mod did not get really hot - you applied enough mechanical pressure to puncture it, causing the battery to vent.

The holes were about a 1/4 inch apart from each other. And in relation to the exact center of the negative side, they were positioned about 1/8th of an inch upward. well i say upward because from my viewing perspective it was in fact upward, but you get the point. Anyways i am 99.9% positive that i just shorted out the battery when the positive side came in contact with the ego to 510 converter. But who know... maybe dropping it did the trick!
Sorry to hear about the battery issue. Stay safe!
I am actually knee deep in the hunt for batteries, after receiving my first mech. mod. I have done quite a bit of research- Bassfiend316 has it right on volts. I have to ask the question, did you verify the battery authenticity? If so disreguard this next part, its a tangent.
My research notes are as follows:
If you are looking to authenticate your VTC batteries, there are some ways to determine this which include:
Each battery "should" weigh approximately 45 grams or 1.58733 ounces with only +-1g error
Each battery "should" have a unique QR code
Visually, you can pick out some key factors. The best site I have seen for this is:

This only my 2 cents, I'm not an expert. Infact I'm just an overeducated n00b. I want to purchase some of the VTC 4's or 5's for my first mech mod- however, amazon has no real reputable sources, imo. I am picking up some eFest purples from the local B&M for the time being.
I wish you luck, hopefully nothing serious happens!

I did weigh the battery and it read 45grams but i did notice the QR code print seemed to be in ink and looking like a fake... everything else on it was in relation to an authentic VTC 4 battery. Either way i need a new battery. Im going to call and notify VaporDNA of what happened and hopefully recieve a new authentic battery.
So if you don't know the story already its in my thread titled "Sony VTC 4 Leaking Battery Acid?". Anyways, I really don't feel like touching this battery because i don't want to risk having this thing go off in my hand. Any ideas on how to properly dispose and get rid of the battery?
Here are the photos
I do have videos of me poking around at the battery and hearing hissing noises but i am going to refrain from posting them because certain people negatively exploit things like this and that's how certain laws are made. Safety is always first. Yeah i know i sound like your dusty grandpa but hey ive seen acquaintances with missing hands and thumbs.
The picture quality is not as good as before i uploaded them. Any ideas on how i can upload photos without sacrificing quality for you guys to view?

well its definitely not battery acid because these batteries dont have acid in them. batteries that contain acid are ones like car batteries. In the car battery example it uses lead plates submerged in an electrolyte solution composed of H2O and H2SO4, or sulfuric acid. VTC4s are solid state batteries which mean they do not utilize an electrolyte solution. they can however vent other nasty chemicals. without further information about the setup you were using it on and the events leading up to this venting, no one is really going to be able to help you ascertain why exactly this happened.
The administrator just merged the old thread with this thread so you should be able to find the information you need
the full charge of an 18650 is actually 4.2 volts. i dont recall why they are listed as 3.7. im not familiar with the mod, but is there anything on the negative side that would correlate with the holes you observed in the negative side of the battery? did you inspect the battery prior to using it? i ask because im wondering if maybe those holes were already present before you tightened the bottom cap
lol id be super impressed if he managed to come up with a 0.01 ohm coil in an ego threaded device
Haha i know i shorted it. I find the two holes on the negative side of the battery to be odd because i didnt apply enough force to puncture it thats for sure but i did drop the battery, but it was dropped on a surface that couldnt really leave 2 pin point sized holes like that.
I did inspect the battery prior to using it and no there were not any holes of any sort or marks on the negative side. Nothing on the negative end of the mech mod correlates with the holes on the battery. But i just now notice 2 extremely small burn marks on the negative end of the mech mod which must have been caused from the liquid coming out of the battery. ill post a picture
