External Battery Safety

 External batteries such as 18650, 26650 and 18350 are used as a replacement cell for many e-Cig’s and mods. They are a rechargeable cell which can be charged using specific chargers and in many cases, can be charged in the mod depending on the manufacturer and their recommendations. External batteries can be potentially dangerous to the user if the safety guidelines are not adhered to. These batteries, like all other batteries we are all familiar with, have a positive and negative pole exposed to the elements with the main body of the battery wrapped in silicone insulation.

 Battery safety is one of the many subjects that we at eSmoke Store strive to practice in the modern society of vaping. Vaping has made some poor appearances in press in the last twelve months due to batteries “venting” while stored incorrectly by the user. One extreme example of incorrectly storing batteries would include carrying exposed batteries in pockets along with loose metal objects such as screws, coins and even the e-cigarette themselves. Due to all of this, I would like to point out the main points of battery safety for your health and safety.

  1. Always ensure that you read the manual for all equipment regarding the correct use of batteries required for each unit before use.
  2. Visually inspect your batteries before use. You should look for any damage to the insulation making sure that the main body of the battery is not exposed. Make sure there is no impact damage such as dents and scrapes. Sometimes removing a battery from a mod can damage the insulation. If there is any indication of the battery leaking the battery must be disposed of immediately.
  3. Make sure you have a carry case for your batteries when transporting them. Cases for batteries are readily available, and it is strongly advised to use them. Using cases ensures that when batteries are stored, there is very little risk of any metal objects making contact with exposed positive and negative poles. If batteries are carried in pockets, purses and bags, they can and will heat up. Batteries exposed to heat, naturally discharge their power and will leak, expand and explode. Not necessarily in this order. It is quite possible the worst can happen without the other processes.
  4. When storing batteries while not in use, they have to be stored in a dry and cool place making sure that they do not get exposed to direct sunlight and that the batteries are stored at room temperature. They should never be in a damp environment as water is a conductor. It is very likely that the dampness can get between the battery and the insulation, which can be very fatal to the user.
  5. Never create a circuit with your battery by connecting the two ends with metal objects. This circuit is highly dangerous as the battery will try its hardest to charge and discharge itself simultaneously and eventually will expand in size before splitting. This also becomes a serious fire hazard.
  6. When charging batteries, the charger should be inspected too. Check that the spring to hold the batteries moves freely and there is no foreign objects on the charging unit. Never leave batteries charging unattended and remove batteries once they are charged. Do not ignore any warnings that the charger signals at any time.
  7. When a battery indicates that it is low or empty, this does not mean there is no power stored in the batteries cell. A dead battery should be treated as potentially dangerous as a full battery.
  8. If the battery gives off an odour or becomes discoloured, the battery should be disposed of immediately.
  9. When inserting batteries into mods, ensure that the battery tray is not obstructed in any way.
  10. Only use batteries from reputable manufacturers such as Samsung or LG.
