Carrying Your E-Cig Safely
Carrying your e-cig safely is easy, but if you do it wrong and end up with a short circuit you can run into some serious problems. The risks are vastly reduced with beginner level e-cigs, but it’s still important to understand why you shouldn’t carry loose batteries in your pocket with keys, coins or anything else metallic and learn how to guard yourself against potential issues.
- A short circuit is like a shortcut for electricity, giving it a low-resistance path to travel and therefore greatly increasing the current draw on your battery, potentially to the point of failure. This process generates a lot of heat, possibly melting wires destroying components and killing your battery.
- Loose batteries should never be carried in the same pocket as your keys, coins or any other metallic object.
- You can protect yourself against the risk of shorts by using a carry case, turning the e-cig off if possible, keeping the cartomizer or clearomizer attached to the battery (if you don’t have a carry case) and – again – keeping it away from any other metallic objects.
Here’s a quick tip to ensure the safety of yourself and others around you when carrying your e-cig. It’s vital to always make sure you turn your device off before carrying your e-cig in your pocket, purse, or the like. Anything can easily hit and activate your device and cause you danger. If your device doesn’t have a shutoff switch, I don’t recommend carrying it along with you without keeping a constant check on it. What I like to do is check to make sure my device is turned off just in case, even if I know I turned it off. Not to sound too corny, but when it comes to e-cigs, safety should always come first.

Minimizing the Risk of E-Cig Mod Explosions
Explosions or bottle-rocket like venting with flames events are the scariest things that can happen with your e-cig, and it doesn’t become a serious concern until you step into the world of mods. Mechanical mods are undoubtedly the primary concern, but learning how to minimize the risk of explosions and “thermal runaway” events is essential for mod-loving vapers.
- Thermal runaway is a potential issue for any lithium-based battery, including the ones in laptops and phones. Rising internal heat in the battery causes further heating in a self-perpetuating cycle, leading to venting and – if confined – explosions. However, these events are extremely rare, especially if you spend more for a high-quality battery.
- Stacking batteries is dangerous – most of the explosions so far have involved mechanical tube mods with stacked batteries.
- You can reduce your risk by using “safer chemistry” IMR batteries (lithium manganese), using an “intelligent” charger (and following the charging advice from earlier), ensuring that all mechanical tube mods have electronic and physical safety features such as vent holes and protective circuits (which are built into most VV/VW devices) and following the advice given earlier on protecting against short circuits.
- If your battery gets hot, vents hot, flaming gas or swells up, you should get it away from you as quickly as possible. If it isn’t dangerous, remove the battery from the mod and put it somewhere it can’t do damage to anyone, but if it’s likely to be too hot, just move the entire mod to a suitable location.
From a personal perspective, I will only ever use AW IMR batteries that use the safe chemistry. I have always felt comfortable using them but I’m very mindful that no battery is completely risk free from failure so if I notice anything strange going on that appears out of the ordinary then I will dispose of the battery and purchase a replacement.
In all honesty, I’m not 100% sure what the correct procedure is should you ever notice that a battery is overheating, but on the single rare occasion this has happened to me I immediately removed the battery and placed it outside out of harm’s way. I waited a few hours before returning to it and then disposed of it immediately.
In this rare circumstance it’s vitally important to investigate what caused the issue before trying again with another battery. In my case, the rubber grommet that separates the positive and negative connections of the atomiser had failed which in turn created a short.

E-Cig Mod Battery Safety and Ohm’s Law
Every battery has a limit on how much current it can provide, and if you go over this limit you’re running the risk of suffering a catastrophic failure. As with most other mod safety topics, this is particularly important for anybody using a mechanical mod. The core principle is that of Ohm’s law, and the maximum amount of amps your battery is capable of putting out, but it also has implications for when you build your own coil.
- Ohm’s law says that current (in amps, A) is equal to voltage (V) divided by resistance (in ohms, Ω), so you draw more current from the battery when you push the voltage or lower the resistance.
- Each battery is rated for maximum continuous discharge current, and this figure tells you how many amps a battery can provide. The Sony US18650VCT4 (or VCT3) offers up to 30 A, making it the best option if you’re likely to draw a high current. For AW IMR batteries, the 18650 (2000 mAh) can go up to 10 A, the 18650 (1600 mAh) can go up to 24 A, the 18490 offers up to 16.5 A and the 18350 can handle a maximum of 6 A. These are likely to be overestimates, so it’s better to assume a lower limit.
- If you don’t have access to the maximum continuous discharge current for your battery, find the C-rating and multiply it by the capacity (given in mAh) to find it, remembering that 1 A = 1000 mA.
- Low resistance atomizers make high current draw more likely, so it’s best to keep your builds over 0.8 Ω and use a large battery where possible.
Know what you’re doing! know what your battery is capable of!
If you’re into sub-ohming or want to get into it, it’s important to know about the resistance you’re building, that you don’t have a short, and the amp draw it will require. This is why I recommend only two batteries at this point, the Sony us18650vct3 1600 mAh and the Sony us18650vtc4 2100 mAh. Are there others you can use? Absolutely! But since these have the highest amp rating of any battery I know, 30A, it’s what I like to recommend.
Remember, the only thing that should be getting hot is your coil!
