1) Leaving your vape turned on when you aren't using it. Not only does turning your vape off when you aren't using it preserve your battery life, but it will ensure that nothing in your pocket, purse, or bag hits the sensitive vape "fire" button which will begin heating up your vape and can burn your coil in the process. If your coils are only lasting a couple days, this tip should help extend your coil life drastically.
2) Leaving your vape in the heat or in direct sunlight. Leaving your vape outside, in the car, in a humid room, or anywhere that can cause the vape to heat up - even slightly - is a bad idea. First of all, when the glass or plastic tank is exposed to temperature changes, it will likely crack and need to be replaced. Furthermore, when the juice thins due to the heat exposure, it has a very good chance of beginning to leak out of the device and make a mess, wasting your e-liquid in the process. If you find your vape leaks more than normal, this tip may solve your issue!
3) Batteries. Mod batteries can be dangerous if used irresponsibly. We created the following diagram to help summarize mod battery safety:
