My original posting regarding this incident and issue is located here (http://www.e-cigarette-forum.com/forum/ego-type-models/293403-echo-thread-part-2-a-66.html). As you can imagine, being in the room when the battery's innards blew out onto my bedroom floor and caught fire next to one of my bedroom dressers was a pretty darn frightening experience. I am just glad I was in the room when the incident occurred, for as for all I know the house could have otherwise eventually caught on fire and burned down to the ground. I am currently in touch with the domestic U.S. retail supplier I received the battery and charger from, Cropduster901 eCigs, Vaporizers and Supplies, and with the original Chinese manufacturer, Hangsen - The leading electronic cigarette and E-liquid manufacturer. Contact Us in order to get the issue reported, and to also see if any corrective measures can be taken from the manufacturer regarding damages from the incident.

I will keep members posted on updates here and on the original thread. Essentially, I just want to make sure users of these devices are aware I had this incident occur, and to take appropriate care when using ECHO batteries and charges from the manufacturer, Hangsen. Likely, the battery, or possibly the charger (or possibly even both?) were defective - though they did work perfectly fine for at least two weeks prior to the explosion and fire. As far as I know at this time, this could possibly happen to anyone that uses ECHO batteries at anytime, even with equipment you've had for awhile. The ECHO battery that blew up and caught fire was a later model black 650mah unit. One of the newer models that doesn't have an LED on the end, but instead has a very small blue LED on the battery body, near the tip where a larger LED would otherwise normally be. The USB charger and USB charger wall plugin unit were also late model.

I had only just fairly recently started using the ECHO e-cigarette, and had been in the process of switching over from using my old m402 e-cigarette gear. The m402 stuff has worked perfectly fine (or well enough at least) without any issues of this nature for over the last 2 years I've been using m402 equipment. I am very disappointed and concerned, as you can well imagine. I really liked the ECHO e-cigarette gear, and up until just now had just recently been highly praising it to others as very nice equipment. Up until now I thought the ECHO is probably the greatest fat battery automatic that there is currently available out there, and in the 650mah size it really isn't all that big. My wife, who is expecting a baby several months down the road, will be very upset. She will likely try to get me to quit using e-cigarettes altogether, which I am currently unwilling to do. The scorched and melted carpet damage done by the exploding and flaming battery innards is not something that can be cleaned up. I've tried. Some other, more permanent solution will have to be found. I think I have some carpet remnants somewhere in the garage that can be used for the repair job. I have no idea how much that will cost. Wonderful, as if I don't have enough new expenses to deal with already, eh?

I just want any other users of current ECHO model e-cigarette batteries to be forewarned that this could be a serious issue they need to be aware of. I have no idea what exactly you should do, other than always be around when these batteries are charging, and take the battery off of the charger once charging is completed. That used to be what people often did back in the early days of e-cigarette devices, though supposedly modern batteries and chargers no longer require so much user attention anymore. I am even a bit scared to use and charge my older m402 e-cigarettes, but for now I will just have to, at least until I hear back from Hangsen. Regardless, I may never go back to using the ECHO e-cigarette at all. I'm not sure how I could ever justify doing so, to myself or to my wife. I just hope she'll be happy I'm alive, that the house didn't burn down, and that the damage is relatively minimal and repairable compared to what might have otherwise happened if I wasn't around.

There are some pictures of the self-destructed battery and the fire damage at the original posting (link listed above at the start of this thread). I will not bother to post them again here, as that just seems like an unnecessary waste of ECF server resources. They are pretty scary pictures in terms of imagining that happening at your home while you are away, unable to respond immediately to the potential fire damage. Once again, this is a safety warning about a possible issue all ECHO e-cigarette users should be concerned with. Be careful when charging these things. Be around when they are charging. Remove them after they are charged. Or, you could just not use these ECHO e-cigarette batteries at all, but I haven't heard of this happening before, so I really have no idea, and cannot say for a certainty to not use them at all anymore.

This could just be a total fluke of an incident. Just be careful with these things if you use them. Very careful. That is all that I am saying for now. For those that are interested, the power plug this battery and charger were plugged into still appears to be working perfectly fine. I don't believe this had anything to do with a household electrical issue. In fact, shortly after the incident, the emptied out body of the battery was still plugged into the USB charger, plugged into the wall, with the LED lights still on for both the USB charger and the wall plugin unit the USB charger plugs into. I don't think the issue was with either of those (built to work together), or you'd think one or the other, or both, would be completely dead. However, I'm no electrician, so I simply don't know for sure. Just be very careful with these things.

For greater battery charging safety I ordered a Belkin Conserve Socket F7C009q Energy-Saving Outlet (which has a 1/2 hour, 3 hour and 6 hour power auto-cutoff timer switch on it), plus one Integy Large LiPO Guard Charging Bag INTC22532 (11.7 x 9 x 0.4 inches), and one Cables to Go 1.5 ft 1 to 4 Power Cord Splitter (to run from the Belkin outlet plug power auto-shutoff timer into the LiPO bag for multiple battery charging). All of these items cost only about $5 to $10 a piece on Amazon, which wasn't a bad deal at all with free Super Saver Shipping (Amazon Prime). They are all also fairly compact and portable for use when traveling, at a hotel or wherever else. I will charge my ECHO batteries in that bag with the timer set to shutoff automatically after 3 hours (which is sufficient for the newer ECH 650mAh batteries and chargers). That will be in my kitchen, where everything is tile, both the counter top and floor, but I will also have the bag sitting in a small metal baking pan - for extra protection. I think that will be a pretty safe setup that will work well for charging 650mAh ECHO batteries.

I also bought another black 650mAh battery today, from a different supplier, as (interestingly enough) my other supplier is not selling this type of battery anymore - at least not for now, though that supplier still sells that model size's e-cigarette starter kits. I also got a few extra dual-coil cartomizers, which I like quite a bit - though they are not all that different in overall performance compared to the standard single-coil ECHO cartomizers. The single-coils are milder in throat hit & vapor production, but more e-juice flavor comes through.

Doing all that makes me feel quite a bit better, but I was (and still am) depressed about the damage to my bedroom carpet. Because of that, I used a Dremel tool and several different grinding tips (using scissors would have taken too long) to grind the hard burnt pieces of carpet down to fresh, cleaner carpet, then rewashed the whole area, finishing with several vacuum passes. I even used a bit of bleach to try and lighten some of the areas of carpet darkened by smoke. The results were far from perfect, but now the spot looks more like something of an old spilled drink stain, rather than something scorched with a torch. The area of damage is over a foot long, so it will sadly always be noticeable, and be a constant reminder of that terrible day when the battery blew up, but it doesn't look nearly as bad as it used to. I'll see what I can find out about maybe some other methods of getting the smoke stains out better. Lesson learned, eh?

Many people use much larger/longer PV batteries, at least up to 1300mAh, and even larger. I don't think it is practical for those that are charging batteries that size, that take several hours to recharge (overnight?), to be constantly monitoring the charging battery's status and condition. Even if one were to notice that a charging battery was seriously overheating, I for one don't think I would try to grab it and unplug it, as it might go off in my hand - which would be bad news in itself. Some kind of more extensive safety precautions are a must, like using the LiPO charging bags, power plug auto-cutoff timers, and whatever else helps assure greater safety. Having a fire extinguisher and fire blanket handy isn't a bad idea either, and you should probably have those around in your house anyway - especially near your kitchen.

My wife was a little disappointed that I didn't decide to quit using e-cigarettes entirely after this incident, but I am cutting back on their use, and my last order of e-liquids were all made in the next nicotine level down from what I usually order and use. I've only just recently switched over to using the ECHO from using m402 gear (which I had used fairly satisfactorily for quite a long time), and I find the throat hit increase from just using the higher performance ECHO to be great enough that I really don't need as much nicotine in my e-liquids anymore. So that is something at least, eh?

I have yet to hear anything back regarding this incident from the battery manufacturer, Hangsen. I didn't really expect a significant response back from them, but I am disappointed anyway. I don't expect they will be doing anything about my carpet anyway, but I at least would have thought they would be interested in getting more information, so as to track down the lot number this defective battery came from and that sort of thing - the basics you would minimally expect from any reputable manufacturer concerned with the safety of their customers. I would have also at least expected them to express an interest in replacing the self-destructed battery for me, and its charging unit. They may still get back in touch with me, but I am doubtful at this point. I guess low expectations are probably the norm when dealing with this overseas e-cigarette manufactures. That is really too bad. I wish Hangsen was not the only source out there for these automatic fat batteries. Their reliability of automatic function truly impressive compared to any other automatic e-cigarette battery I have ever tried. Hopefully some other manufacturers will be coming out with better automatics sometime soon, so I can switch away from Hangsen and twiddle my middle finger at them.

Hmmm...no, I hadn't reported the incident on that thread (I'd never heard of it before), but it seems very clear that thread is specifically only for reporting APV (tube or box 'mod') gas vent incidents. There is nothing there indicating that any other kind of device failure reports are being taken. However, I am looking at the report page the link in that thread goes to. Though some of the questions contained in it pertain specifically to "mods", I am nonetheless going ahead with filling out the form and submitting it for what it is worth, with links to the incident photos I took and posted on the forum earlier. I don't know if anything much will come of it, but I thank you for letting me know about this report form. Filling it out and submitting it has helped me out some as far as getting over the initial shock, anger and depression I've been dealing with ever since the incident first occurred.

I can only imagine, but I am so glad you were home and no one was injured... physically.
Best to you, billy.

Yeah, I've done about everything I can to get over this and charge all of my batteries much more safely now. I'm just still a little peeved that I had to go through all of this in the first place. Everyone here on the forum has been very supportive, which I appreciate very much.

It helps. It helps a lot. Thank you.
