Wait, so "THIS" is the second time you've had CR2s blow up in your face?
Or are there two Eskimos that like using unprotected batteries and explosions?

you can get protected cr2's at dealextreme i thought
Thankfully the "boom" failure mode is the most common these days. Back in the late 90s, when I worked full time for a company called "Battery Works" (no longer in business) we did everything from tiny 3 gram silver oxide watch batteries up to multi-ton forklift and floor scrubber batteries. Those were the days when lithium batteries had 2 modes of failure. I called them "firecracker and road flare" Road flare was more common. Basically it was just elemental lithium reacting with atmospheric water in a very bright and hot manner. Firecracker is what this thread is about. But always remember: It could be worse!
Personally whenever I get around to building/modifying things, I'm actually going to stick to Ni-CAD and Ni-MH cells. They can put out nearly inifnite current when needed, and love to be drained fully. Also cheaper. I could probably vape for a month on a stack of 3 8500mAh SAFT D-Cells. 3.6v@8500mAh
And don't get me wrong. Li-Ion and Li-Poly are great systems. I just prefer that they are designed and implemented in a controlled system by a team of paid engineers who know exactly how they're going to be used and charged.
People comment on how The Copper looks like a pipe bomb.Exactly how dangerous is the copper? How dangerous are my CR2's in a pipe with a potential projectile on the end (the atomizer)?
I'm starting to vape sideways out of fear. In the hopes it will just explode out the side of my mouth rather than through the back of my head.
How about charging your batteries exceedingly before they need to be charged?Originally Posted by balldope
You will have an extra margin of safety and the batteries will last longer as a result.
Exploding Batteries? WTH? KR808 affected?
Okay fairly new to all of this, but after a month of scouring this forum this is the first I've heard of exploding batteries! WTH?
I have no idea about the difference between a protected and unprotected battery? I vape a KR808 portable batteries (as well as the usb passthrough) ~ do those of us using this model need to be concerned about this issue?
And BTW Very glad that OP was not injured ~ very, very frightening indeed!
The copper was my first mod bought and it came with green CR2's (unprotected) ad I noticed the design of the copper dents in the - side of the batt.
I also usually drain them completely before charging. Granted it is a stout unit of brass and screw on caps but does that make it worse? Are the batts explosive enough to make shrapnel out of the brass?
Should I drill the vent hole larger? I have p-CR2's on the way though.
Mary--All Commercal e-cigs that I have encountered have protected batteries and come with the "CE Seal" of Apporval. You only find this issue with Mods.

I bought several of these 10440p from Janty USA - STICK which they claim to be protected because there is a "P" at the end of the number, but I do not see any kind of PCB on them, just what appears to be vent holes on either side of the + button top. Are these protected? If not, how can they claim them, and sell to be protected batteries? I have a laser mod that the regular 10440 PCB batteries just don't want to fit inside, they are too long. The ones from Janty fit perfect. I did drill 2 vent holes on the end cap that the + side of the battery is facing, just in case, but I don't feel very comfortable using these. Do the 10440 explode as often as some of the larger ones I have seen mentioned on the forum?
Wait.. why is this stick-eed?
