My 18350 aw battery just exploded

[trpxcst]

Another reason that I feel the vaping community is more concerned about battery failure than the rest of users of rechargeable batteries is the political aspect.

I don't see too many proposed bans on flashlights, r/c toys, camera flashes, laptops, mobiles, etc... but it seems more and more, there are people out to make vaping look bad (*cough* big pharma/ANTZ *cough*).

Publicizing stories where batteries/pvs have failed causing injury to people or damage to property is just one more way they can try to skew the general public into thinking that vaping should not be allowed.

Come on OP! Is there a chance it shorted in the case? (zipper or no zipper? Metal {not in wrapper} stuff in there or no?)

What bothers me is the concept of an internal short. I've mostly counted on protection PCBs to do their job with Li-Ion. I know there are none in an IMR though (well, most). Now... an internal short would bypass the PCB, right? So can that happen with Li-Ion too? So now I'm thinking I should bite the bullet anyway and just use all IMR........but I can't tell if A) this is really an internal short and B) if that's more common with IMR and not Li-Ion.

Anyway, would depend on if there was a snowball's chance in hades of an external short in whatever bag (color is not the factor here... it's conductivity) it was in. Inquiring minds want to know!

Protection PCBs are designed to prevent the conditions that typically cause internal problems. Overvoltage, under voltage, and over current are the main causes that send a battery into thermal runaway. The other is manufacturer defect, which no PCB or "safe" chemistry can prevent.

(Bolding added)

Yeah, but the safer chemistry doesn't react as fast... hence safer.

What I want to know from the OP is .... IS there a chance that it shorted? Zipper on bag? Type of container? (not what it came with)

Let's keep this in prospective.. it was a battery, not a PV that this happened to. Even though it was a battery that was MEANT to go in a PV..It really has nothing to do with vaping. People buy and use rechargeable batteries for many other things than vaping devices. At work, we use various devices (I work in a hospital OR) that uses AA batts, ..............

AA battery size come in many flavors:

AA Carbon - 1.5v old tech, leaks if left in equipment
AA Alkaline - 1.5v newer tech - NOT rechargable
AA NiCD - 1.5v rechargable, low power draw ability
AA NiMh - 1.2v rechargable, higher power draw, can vent flames if greatly abused (charged in a Li-ion charger) but generally safe if maintained and charged properly
AA NiZn - 1.6v rechargable, even higher energy density from NiMh, REQUIRES special charger, but generally safe if not mis-charged
AA - 14500 Li-ion Primary cell 3.7v - NOT re-chargable, can explode if re-charge is attempted
AA - 14500 Li-ion Secondary unprotected 3.7v - rechargable, used widely in laptops, cell phones, etc...which contain protection circuity to keep the cell from releasing all it's energy if shorted and to safely recharge, monitor the voltage and amperage draw
AA - 14500 Li-ion Secondary protected 3.7v - our vaping cells - contain a small circuit board to prevent over amperage discharge, need to be charged properly, not exceeding 4.2v max, can vent large flame if abused
AA - 14500 Li-ion IMR Secondary unprotected - (the OP's battery) uses safer chemistry instead of relying on a cheap circuit board, can overheat - go into thermal runaway but don't violently vent like some Li-ion can.
AA - 14500 Li-(too many variations to list) various levels of safety, and protection needed.

Much more indepth information available here:
Battery Information Table of Contents, Basic to Advanced

I don't usually take spare batts when I go out. but when I do, I carry them in a plastic battery case. I don't know if this is safer or not.

Much safer, less chance of the battery shorting against change in your pocket or purse.
Be aware a physical shock to the battery can cause internal damage, invisible that can cause an internal short.

Hi Atty, OP said early on it was in a plastic battery case with a carto in it's condoms, sorta figure there was some kind of internal damage, caused by ??????

 

[Myk]

there are people out to make vaping look bad (*cough* big tobacco *cough*).

Psst, big *cough* tobacco is our ally. They have the money to fight big government and reduced risk nicotine/tobacco is the future of their income.
If you want an enemy try big pharma and the ANTZ.

 

[Speedgoat]

It was in a black case that I got with my lava tube only thing in it was 1 battery a cartomizer and a plastic mouth piece

This is the only thing I could find about the case (I still might have missed it). I dont know what case comes with the LT, but is it possible that it has metal in it? That the metal in the case and the carto touched opposite sides of the battery and created the short? Carto touches positive and case, case touches negative and carto.

Still no pictures of this Battery, I'd still like to see some PICS of it just to see what it looks like, OP said AW 18350 so I'm assuming it's a AW 18350IMR,,,, Can we please see some pics of this AW 18350IMR that exploded please.

 

[mwa102464]

I understand that but it wasn't being used.. It was sitting and doing nothing when it exploded. It worked fine when it was used over a week ago... Not understand why all the sudden out of literally no where it exploded.

An AW 18350IMR I dont believe exploded, if anything it may have went into thermal runway pushing out heat and gas at best and vented, and in a plastic case I think it would catch it on fire, but explode ? and AW 18650IMR has been shorted from a full charge and only vented in a demonstration, so are you using the word explode as vented and pushed out a small flame and gas or are you using it as it truly exploded jacquelyn ? You said you had taken pictures in one of your post but couldnt upload them on your PC, have you gotten them uploaded yet ? I'm not questioning something didnt happen, I would just like to see the actual battery if I could please so I can see the real result of what happen here. thanks

 

[Stosh]

@mwa, the OP may be overstating it as an explosion, sounds more like the IMR overheated and vented a bit, but did not explode as the safe chemistry should not have...

from the OP

I started smelling something funky, than I heard it explode and my Gucci purse was crazy hot) thank goodness it didn't blow me or my purse up because it was on my lap

If a regular Li-ion, even protected, went into thermal runaway and vented the Gucci and the lap would not be totally unscathed.

 

[joe98200]

OP has an iPad, but can't put pics on computer and upload to ECF from there as soon as the topic was made? OP will surely deliver...

Then again, the last time I saw a post like this on ECF, the guy never posted pics either afaik.

... (*cough* big pharm *cough*). Folk need to read the CASAA material!!!

I am giving the OP the benefit of the doubt but would like to mention that browsing through some of her previous posts saw her with a charger that blew up in march. Not sure if is any way connected but maybe the battery was charged with this charger since Op said they have had it awhile but rarely got used. Possibly even a seperate electrical issue in her house. We have phones to our ears and flashlights in our hands that all use similiar batteries. All i'm saying is this doesnt seem to be the first time she's had things blow up on her when I have yet to see any in my lifetime.

 

[MustangSallie]

The OP definitely has a run of bad luck. This is not her first exploding battery: http://www.e-cigarette-forum.com/fo...hot-summer-weather-batteries.html#post6223056

 

[Swer3397]

Yah, I wonder if she just got some crazy powersurge issues in her home or something. IDK enough about it to be sure.

And my God that purse has been through alot. Maybe it's cursed.

 

[MustangSallie]

Not to make light of a scary situation, but I think I just found a way to justify a Gucci purse to my husband.

Day-um, just your avi would convince me to buy ya any frackin' purse ya wanted (if ya were my bride, even in da past!)!!!

Stosh, believe me I'm up and educated on Batteries , why repeat exactly what I stated ? The post you even quoted says she heard her battery "Explode" and this is what I'm doubting, there is a difference between Explode, and venting with a thermal runway and the IMR Safer chemistry means no risk of venting with flame or explosion in most circumstances unless under pressure with no venting applicable when and where stored.. People need to be careful either way too. I would just like to know more about what exactly happen, AND SEE THE BATT.

I'm also not questioning the fact that she had some type of issue with her AW18350IMR, however I am questioning it exploded as she stated, and would like to see pictures of the Batt too. The OP stated she was going to upload the pics she took,,, an exploded Batt wouldnt have much of a picture to post, and one of the reason I think it was more of a venting situation with heat, rather then Exploding because apparently there is still a Batt . I just want to make sure of what really happen, I would like to hear from the OP and see the pics.

She also posted on 05-28-2012 that she had an 18650 Batt explode in her purse the month before 05-28-2012 so in April that would put this one happening, With that said something doesnt sound to right here, and a little fishy in my opinion. 2 Batt explosions in a purse in 3 months ? cmon now

You can count the amount of AW Batteries exploding while vaping with one hand and still have fingers left over but the same person with 2 in 3 months and both in the purse, uhm just uhm I'll leave it at that. And if so user error of some sort I'm sure of.

Lastly please Note ; here is a fully charged 4.2V AW 18650 IMR Batt fully shorted for 14 minutes till dead , note no explosion, no noise, no fire, no flame, just heat = http://www.youtube.com/watch?v=haMDZOfjqsE

 

[Swer3397]

It's the purse. When they said it was "electrifying" they must have meant it.

Also it is July 4th today - she's prolly spending it with family. God...do you guys think she has the purse with her around all those people? Hope not!
