So what causes batteries to explode?

Battery Safety

  • Storage
  • Wrapping
  • Inappropriate batteries
  • Proper charging methods


Proper storage of your batteries is critical in preventing an explosion. One great way to ensure you are doing this properly is to google how to store the kind of vape batteries you have, and make sure they are the correct type of battery for the type mod you are using. Also, leaving them loose in your pocket, purse, backpack or car is dangerous! Because of what your batteries are made up of, it is possible for them to react to excessive heat, or loose change in your pocket or other items you have them around. Always use special battery cases to safely store your batteries.


Using 18650 batteries with a torn wrap is dangerous. This is because the entire body of the battery is a negative terminal. Without a proper wrap, your 18650 could short and cause a harmful explosion. Never use a battery with torn, or damaged wrapping.

Inappropriate Batteries

E-Juice Plug advises users to have a clear understanding of what type of batteries your mod needs. Check many sources and do your homework. Using the correct batteries will help ensure you do not go up in flames in a vape explosion. Most mods are regulated to combat this danger, so make sure your mod is regulated. Batteries have a threshold for the amps they can supply. So, when you build low-resistance coils or even with mechanical unregulated mods you need to know which batteries will be able to keep up. If the atomizer setup you are utilizing uses more amperage than the battery is able to put out, your battery will overheat, and go into thermal runaway. Without being able to breathe, the battery will overheat, swell, and explode. E-Juice Plug strongly advises only advanced and experienced users to build coils if using mechanical/unregulated mods.  If you are new to vaping ejuice plug recommends starting out with a regulated mod, and using a high amp battery with a 2500 mah or higher. Check out our selection of batteries here. Make sure to always read the manufacturer’s recommended batteries to use with the mod.

Correctly Charging 18650 Batteries

Although the previously mentioned methods of screwing up are the most common, there are other things people do that cause vape explosions. This includes vaping while charging their device - a big no no! Just think about it as the battery is receiving a current of power surging through possibly an uneven rate. Powering up and draining the battery at the same time could damage the battery or worse cause it to explode!  Improper charging is also a common issue, it is highly recommended to always charge your batteries in an external charger like these here at E-Juice Plug. Charging the batteries in an external charger is safer for several reasons. The batteries will have a more even charge and removing them from the device will ensure you are visually inspecting the batteries on a regular basis for any damage they may have. Don't buy fake batteries, at E-Juice Plug all of our products are from a trusted source.
