Why mods explode

and most importantly — how to avoid this
To begin with, the title of this article is not entirely correct. Mods themselves do not explode, it’s the batteries inside them that do. How does this happen? Very simple. The battery starts to work when the positive and negative sides are connected. This usually happens when you press the button on your mod. The current goes to the coil on the atomizer, everything is fine. It seems like nothing could go wrong.

But sometimes the battery can short circuit. For example, something heavy falls on it and the internal contacts get damaged. In this case the battery starts to heat up with all its might, and it’s almost impossible to stop. It overheats, accumulates gases, the pressure inside the case becomes critical — and that’s when the real fun begins. The positive side starts spewing hot gas or even flames. If the battery is inside of a mod, then the mod can catch fire or even explode.

In all fairness, when the battery is inside a mod, it’s harder to damage it. Doing so requires talent and luck. It is, however, possible to short it out. In such a case circuit board-based mods will simply stop working, but a mech mod will begin violently heating up. You’re lucky if it has ventilation holes.
If this happens, do not try to prevent the inevitable. Don't try taking out the batteries or removing the RDA. You'll only have a couple seconds to get back to a safe distance. Most importantly — take care of your hands and face.

(experienced pyromaniacs may object, claiming that you can remove the RDA and release the button just fine — but we advise against the risk, as eyes and fingers are more valuable)

Now on how to avoid this

Don't use bad batteries. 'Bad' means bought from shady third parties or pulled out of a laptop. Buy batteries from reputable manufacturers, and only in trusted stores. Otherwise, they may suddenly fail with an unpredictable degree of magnificence.

Handle batteries with care. Don't drop them or carry them together with metal things. By themselves, they are much more fragile and fire-hazardous than in a device. Use special cases or at least wrap them up into something.

If possible, don't start with mechanical devices. If you've managed to get a mech mod after all — treat it with care and love. We've already published a guide on how to take care of mods, so we're not gonna repeat ourselves. Though it bears mentioning that in the case of mech mods you should be extra careful when choosing batteries: only high-current, only authentic, and without damage to their wrapping.
Battery shrink wrap is like wire insulation. If it's damaged, the chances of a battery short circuit go up. Circuit board-based mods are not afraid of this, but a mech mod (unless it comes with special protection — for example, like Subzero X) will immediately go into hand grenade mode. That's when you need to be careful.
If you have a 2−3 battery mod, try not to separate the batteries. Not because they will miss each other — it’s because otherwise they will discharge unevenly, and at some point one of them may simply fail. This can mean an explosion for your mech mod.

If you charge your mod via micro-USB, don’t vape when charging. Even if this is a specified feature. There’s still a small risk that something will go wrong. It’s generally better to use a dedicated charger: it charges faster and protects against overcharging.

To sum up, we can say that mods rarely explode, so you generally have nothing to worry about. Choose batteries wisely, treat them well, and everything will be fine.
