    OMG
    is this what happens mainly with battery knock-offs and bad quality bateries or improper usage, exposure to heat, etc., or is this something that can happen to any vape/battery on the market?

    Hard to tell, but often in these cases further investigation revealed that the user had something seriously wrong in his setup and/or usage.

    The modern IMR/INR high discharge cells that we use are way safer than previous generations and than other notoriously dangerous chemistries. But there are still risks of course.

    It must be noted that all big name cells are tested under extreme conditions (including direct prolonged shorts) and are all designed to "vent gracefully" instead of exploding and catching fire. But you can still create easily a pipe bomb if your device doesn't have enough vent holes in the proper locations (I could point the finger on the Herbstick Eco here for instance which has a meager single small diameter hole at the bottom of a closed metal tube, the X-Max/Storm being only marginally better as there are more holes but the positive side of the cell is opposite to them...)

    I think that my portable vape doesn't have any vent hole so that's a ticking bomb if the battery goes "bad" :-(.
    I'm using original battery afcours. I think it's LG or Samsung.

    I can almost guarantee you that most if not all of these people were using a sub-ohm tank on a hybrid mod, which is asking for trouble big time. These batteries are quite safe if maintained properly and used correctly. As long as you know and follow the basic safety considerations of the device and batteries you're using and buy legitimate cells from reputable sellers, the chance of something exploding on you like this are slim to none.

    Good detailed explanation about the dangers of hybrid mods and why, specifically, they should never be used with sub-ohm tanks. Personally, I just wouldn't use them at all.

    Just to give some perspective. Its rare for this type of thing to happen.
    Im a firefighter with 16 years experience in 2 of the UKs busiest fire stations. I have seen one fire caused by a battery. It was a replacement/chinese copy dell laptop battery.
    Consider how many batteries are in all the homes in my cities that Ive served in.
    It must be many millions.
    Millions of batteries over 16 years and i can recall 1 confirmed battery fire.
    So i would say yes it happens but be sensible and be careful, have a smoke detector and youll be fine!
    Youre much more likely to suffer a kitchen fire caused by carelessness.

    Aaaggggh!! You guys have me all concerned over my batteries now:)
    Any good caps for 18650s? Like the MFLB battery caps.
    I've Google'd it with no results. Plenty of cases though.

    I had no idea until this week that these batteries are so potentially dangerous. I've always just left my batteries on the charger until ready to use- days or sometimes weeks. Now I'm not even sure where to keep them between use- I don't have enough of those little plastic containers. I'd be so tempted to just switch to butane and desktop but between the tubo evic, zion and milaana it would be hard to give up batteries.
    We all should have this info.

    Keep them in a drawer, or a box, or just leave them on top of your desk like I do. Leaving them in the charger for more than a few hours isn't good for the batteries. Other than that, there's no reason to worry about storing them as long as there's no way they can accidentally discharge. They don't need special containers. They are no more dangerous to store than any other kind of battery. The potential for danger comes during charging or discharging, not from lying around. While 18650s should be treated with respect, the actual danger from them is not nearly as much as the hype would have you believe.

    @Ratchett has them at his site. They work great but I actually prefer the plastic containers after buying both.

    @little maggie , said plastic containers are <$1.00 each and can be bought locally at any vaporizer shop, way worth it. I just put a piece of duct tape on a few, and those marked containers signify my drained batteries that need to be charged - fresh ones go in unmarked containers.

    You could replace "not" by "no longer" in your sentence. Earlier chemistries were definitely more dangerous but the IMR/INR and other relatively recent developments that we use are indeed way safer now.

    (cf. my previous remark about "vent gracefully" instead of catching fire)

    You bring up a good reason to use some kind of container: battery management. Mine are numbered with a Sharpie, in pairs if for the Zion. I don't use containers to separate used from fully charged because I put depleted batteries on the charger as soon as I remove them from the device. If you can't do that, then plastic containers are a good idea.

    Agreed.

    These are my favorite 18650 cases for single battery storage. What I do is place them positive side up when charged and negative side up when discharged. Only .55 each through Illumn.

    All of the info on safety and good practices is very welcome. But what about a situation where the vape maker says only use our batteries, but 'their' batteries turn out to be not particularly high quality generics anyone can buy from Ali baba by the thousands. I understand the real experts aren't ever going to say anything besides heed the vape makers warning, but the chances that this generic is actually engineered for that vape, or that vape is optimized around this generic battery, seem miniscule.

    How crazy would it be to just go ahead and use a high quality lg or Samsung battery, or one of the other name brands off of Mooch's chart?

    Not crazy at all and actually something I would recommend: ditch the OEM rewraps and get the real deal! :tup:

    Especially anything with "fire" in the name...

    So, none of the reportedly custom batteries are anything other than rewaps of standard batteries? I can think of at least a couple vapes that imply that you should only get batteries from them. I suppose if your vape is very sensitive to voltage or output that might be a way to prevent problems...
