Lets Talk Battery Safety

You may have heard that e-cigarettes, or "vapes," can explode and seriously injure people. Although they appear rare, these explosions are dangerous.

The exact causes of such incidents are not yet clear, but some evidence suggests that battery-related issues may lead to explosions. The safety tips below may help you avoid a battery explosion.

Battery Types and Sizes 

You’re probably familiar with the 18650 battery - the Chubby, tall cousin of the AA Battery. It’s the most common battery used in DevicesBut you can also find 10440s, 18500s, 18350s, 22500s, 22650s… You get the point.So, what do all of these numbers mean?It’s really quite simple. These numbers refer to the size of a round lithium ion cell.
  1. Battery diameter (e.g. 18, 22)
  2. Battery height (e.g. 35, 65)
  3. Battery shape (e.g. cylinder, non-cylinder)
As I mentioned above, 18650s are the most common battery size for vape devices. They produce the right amount of voltage, and many of them can handle the high-current discharge necessary for vaping.Round-cell external lithium ions are designed with exposed contacts. Like the AAs in your TV remote, this makes them easy to use in any device where they’ll fit. But also like your AAs, they’re vulnerable to a number of issues:
  • Touching conductive materials (like loose change) to their positive contacts can short and damage them
  • Damaged/torn battery wraps will expose their negative contacts, making them dangerous to handle
  • Conductive debris on either contact can cause a short
  • Inserting your batteries upside down may cause a hard short

Questions our Customers frequently ask our Team.

  • Why can't I use a different charger for my battery if it fits ok?
Please do not ever use a charger that was not meant specifically for your battery.
Doing so could cause serious damage and/or personal harm.
The charger that comes with your battery will have been designed specifically for it and therefore will deliver the correct level of charge.

Using a smartphone or tablet charger or indeed any charger that is not the right type will expose the battery to too high a current.
*Please note - batteries on charge should never be left unattended or to charge overnight.
  • What might cause my e cigarette battery to become dangerous?

• Over charging the battery
• Physical damage to the battery, for example caused by it being dropped.
• Excess / over discharging of the battery.


  • What do I do if the battery has been dropped or damaged?

• Inspect the battery carefully to assess if there is any obvious damage. Obviously damaged batteries should be discarded immediately.
• If no visible signs of damage after dropping is present use it in the e cig for a short time only and then recheck it visually.
• Continue to build up the time you use the dropped battery and checking it visually for damage until you are confident that the battery is completely sound.

• If your battery has a Rip or small tear with no cell damage you are able to replace the outer layer.


  • Buy a quality device - A High Quality device is a good investment to make as it greatly reduces the risk of explosions which are common in cheaply made products.
  • Do research before selecting the right battery - if you’ve purchased a vaporizer that doesn’t come with a built-in battery, you’ll need to choose your own. Most standalone Mods are battery not included, and so buying high quality rechargeable 18650 batteries for them from reputable brands is crucial.
  • Buy a quality smart charger - explosions can occur due to overcharging or discharging of batteries. Smart chargers offer more safety features than a regular charger.
  • Use a battery case for transportation - it’s crucial to always carry your extra batteries in a case and not to leave them loose in your bag or pockets. If batteries come into contact with metal objects such as coins or keys, a hazardous explosion can occur as the interaction can complete a circuit between a positive and a negative.
  • Be aware of the weather - Fluctuating temperatures, either extremely hot or extremely cold can damage your device’s battery which could lead to explosions. Batteries are generally safest between 50 and 115 degrees Fahrenheit.
  • Use the correct charging cable - Using a different cable to what your device came with can cause problems because the charger you are using may have a higher voltage than your battery which will cause your device to overheat.



  • Never use damaged batteries - using a damaged battery will never end well. If there appears to be fault, if the wrapping is damaged or frayed, or your battery fails to keep charge, expose of the battery safely.
  • Don’t leave battery charging unattended - not keeping an eye on your vape while it’s charging is a safety risk. Most well-made mods have a cut-off point where they stop charging when they are full but unfortunately this function fails sometimes. In order to avoid overcharging your battery, make sure you check it regularly and never charge at night while you’re sleeping.
  • Don’t exceed the amps of your battery - understanding Ohms Law is a vital part of battery safety. Take the discharge rate (the amps) divide it by your voltage level by coil resistance (ohms) and never exceed this rating.
  • Don’t charge or rest your device on flammable surfaces - Never rest your mod on a pillow or flammable device and it’s important to prevent exposure to direct sunlight. Therefore, don’t leave it in your car or on your windowsill for long periods of time.
  • Don’t mix and match sets of batteries or battery chargers - while many batteries and chargers may look the same, you should never mix and match these components because the voltage output may be different which will damage your batteries.
  • Never over-discharge your battery - This can be as harmful as overcharging your device as it cause serious damage and weakens your battery.
