Ok I have read one other post where a non-protected li-ion battery exploded. Luckily the user was in no way hurt. Today I got to see for myself what kind of force is created by these tiny cells when they explode. First the basics:
The batteries were almost new. Only recharged maybe 4 times
They were 2 CR2 3v in a magnum mod that was set to run at 5volts
The batteries were charged the night before on a charger with built in protection.
The mod was used maybe for 4 or 5 drags during the morning before the explosion.
So basically this was definitely not a case of over-charging. It was a case of the batteries allowing a serious over-discharge. I DO NOT vape on 5v all day. This is an occasional (maybe once an hour) hit just for a boost. This was also on a relatively new mod. Only a few weeks old. Nothing showed any kind of wear or any other sign of trouble to come. I have learned that the 801 atty's last a lot longer on high volts if you keep your drags to a 3 second draw. So, this is what I have been doing. No power draws lasting 5 or more seconds here. Leaving my atty connected all night must have sucked some of the juice from my batteries while not is use. I do not usually have to charge these batteries more than every couple of days due to my light usage.
So I go to take my next drag and 2 seconds in BOOM!!!! Holy cow! Ok, I am definitely awake now. If I did not know better I would have sworn someone just fired a shotgun in my living room. It was that loud. On top of that there are pieces of debris everywhere. And lets not forget the smell.
Time to assess the damage.
Ok, as unbelievable as it may seen, the atty is perfectly fine and still produces great vapor and flavor. The batteries did not come out so well. One battery appears perfectly fine (threw it away anyway) the other battery is in several pieces from one end to the other of my living room. So now I collect all pieces and make sure there is no fire anywhere. So far so good. The magnum mod didn't fare well either. The end cap bent in the middle and blew off. The body has a bit of a bulge. Suprising in this is that the top where the atty connects looks just like new.
Now for myself. Well I didn't come out clean either. I have black soot from the massive flash all over my face and the hand that I was holding the mod with. So I clean my face to find that I have the fattest purple lip I have ever had. Well now I can just say I ran into Tyson in the alley. I have also singed my hair, eyebrows, and eyelashes. No wonder it stinks so bad. While showering and washing my hair for the 3rd time I realize that my tongue hurts. Sure enough I look in the mirror and I have a "V" shaped cut in the middle of my tongue. I have no clue how that happened. It is not possible for me to have bitten my tongue in that spot. I think the force of the explosion pushed the end of the atty into my tongue and the shock just kept me from realizing it at the time.
All said and done, I was very lucky. Nothing that won't wash or heal itself in a few days. What have I learned????? No more unprotected batteries. I will be using protected 3.7 volt batteries until they start making protected CR2's. I can wait to use 5v until then. I still have my backup 5v mod to use at that time. For now it's 3.7v for me. Since I own several other mods that currently use 10440 batteries that are also unprotected, I will put them away for a few days until my new protected 3.7 10440's batteries come in.
Many of the veteran members have warned of the hazards of unprotected batteries. I wrongly assumed that the issues would be from charging. So, I never leave charging batteries unattended., Never charge longer than needed. And, I only use protected charges that have 2 separate charge adapters so that one battery never gets over charged while a weaker one is filling up. This is obviously not enough! For those of you who have not experienced one of these tiny batteries blowing up, take my word for it. The explosion will be far larger than you think!!!

Do yourselves a favor, spend the extra few dollars and replace any unprotected batteries with protected ones. If your mods don't have protection in them put them away until you can get protected batteries that fit them. I was home alone today. That was a good thing. I usually have an infant here that I babysit. Imagine if that had happened while I was holding her???????? And do not blame other when/if this happens to you. There are warnings all over the modders section of the dangers of using unprotected batteries. I saw the warnings and though the danger was minimal. I only found one post where a battery had exploded. This is why I am posting this. This is NOT an isolated event. I am sure there are others that simply don't want to look like idiots for not listening to those who know. I for one don't care if I look like an idiot if it saves someone else from what cold be a very serious injury. Please take my advice and go get those protected batteries!!!
Sorry for posting this twice. After posting in "Technical issues" I realized it belonged here.
For those who asked for pictures: The first pic shows the inside of the pvc spacer tube with the faulty battery fused inside. The second pic shows the end cap, the good battery, the other side of the spacer tube and a piece that I am pretty sure used to be part of the battery. The third pic shows all of that plus the totally charred inside of the mod itself (not that yo can actually see anything in there. There were also about a dozen tiny pieces that I cannot find in the trash can at the moment, but you get the idea. NOT COOL!
For those who are interested:
I did take apart the mod once I was sure there was no more issues with the battery. There was no short. All of the wires were perfectly fine. Not even charred. The only issue in this case was the battery itself. After inspecting the mod and putting it all back together, I put a protected 3.7v 18500 in it along with the same atty that was on it when the explosion happened. As unbelievable as it is, it is working perfectly. It appears the only damage was to the batteries, And some soot inside the battery compartment. On the bright side it looks like I get to put this mod back in my daily rotation. Just not with 2 batteries. I will only use 3.7v from here on out.
