One cannot advise others enough, to be very very careful when using unprotected batteries. These are not toys and are effectively hazardous to safety.
And no matter how experienced you might be, in handling them, an accident can still quickly happen.
Which was the case with me today.
I woke up exceptionally early in the morning today, and as usual, took up my best PV and started vaping.
As usual, it was my beloved GG Grant, and inside it, were 2x 3V unprotected Cr2 batteries.
Only 2 puffs later, the batteries started heating. It was a little premature and unusual, but since the temperature was not alarming at this point, I thought I'd keep on vaping.
I couldn't finish my draw when all of the sudden, a battery exploded inside the Grant.
It was not a big explosion, but enough to scare the hell out of me on this lovely morning, especially that heavy fumes started instantly getting out of the holes located in the bottom cap of the Grant.
At this moment, the Grant's temperature had really become very high, and I had already put it on the table in front of me.
I kept contemplating it for few seconds, while the fumes kept getting out of it, and increasing more and more, with a high fizzling sound.
After about 15 seconds, I realized that the worst was still to come. There was a second battery inside it, that might explode at any moment! I had to get that Grant from the table and put it on the ground as quick as possible.
But I was not sure of its temperature at this point. So I reached it out with one finger, in a slight quick touch just to test it, yet managed to get a slight burn. Time was running out. So I grabbed the Grant by the mouthpiece of the atomizer, and quickly put it slowly on the floor.
Then I kept looking at the fumes getting out of it, hoping it will be over soon enough. Yet it didn't stop. The room was already covered with a heavy smog...Then it happened!
A big explosion! That was the second battery. It exploded in a spectacular way, and the blast woke everybody in the house like if a bomb exploded.
The Grant turned instantly with the blast into a flying rocket, where a huge fire was getting out of the three holes in the bottom cap, and the rocket then flied away till it hit a couch, where it landed and a big fire then caught the hole bottom of the Grant and everything around it.
When I say rocket, I mean really a rocket, with fire getting out of the 3 holes simultaneously at a very high pressure, flames reaching at least 30 centimeters in length! It really looked like a spaceship!
At this moment, I instantly jumped on it and started putting out the fire, which was done rather quickly.
I then waited for 5 minutes till I could grab the Grant with a piece of towel and put it on the balcony to cool it down. It was so hot that took more than 15 minutes for the temperature to start dropping.
At a time when it was still too hot to touch, I took few pictures of it while it was still sitting on the floor of the balcony.
In conclusion:
You can see from the pictures that the Grant is almost intact, and only needs its plastic parts and the button's spring changed, although it was subjected to 2 battery explosions and a very very high temperature for many minutes. Any other PV would have surely exploded in my face, causing me serious injuries.
The holes in the bottom cap are the keys for its survival and for my own safety. This was the ultimate test. Those holes diverted the blast and the fumes and the fire, and directed them away from the user's end.
So the safety on the GG is not a matter of theory anymore. It is now more than ever, an undeniable fact, tested and proved in the most extreme of conditions.
Thank you again Imeo, not only because you had already anticipated such risk, but also because you had already built to it, a serious and effective protection measure.
Let that be a lesson and a testimony, for everyone to benefit from it.
Regards.
