Man seriously hurt from exploding 18650 - how a vape shop can prevent this from happening October 27 2015, 8 Comments

The lithium ion battery inside this man’s electronic cigarette exploded, causing him very serious injuries.

His device was a mechanical mod, not a regulated mod. If you do not clearly understand the difference, please take a few minutes to get these points down.

What’s the difference between a mechanical mod and a regulated mod?

A mechanical mod is as simple as it gets, and is dangerous for newbies

  • No internal electronic circuitry or wiring whatsoever.
    • The top cap of the mod connects with the positive end of the battery, and the bottom cap connects with the negative end of the battery.
    • Most mechanical mods have a locking mechanism, which separates the bottom cap from the negative terminal. To complete the circuit you must unlock and press a button.

    So when does it get dangerous?

    Since there is no protection circuitry, a user can easily stress the battery in terms of:

    • over-voltage
    • over-discharge
    • over-amperage
    • over-temperature

    All of which, can cause a battery to smoke, fire, or explode.

    A regulated mod is more complicated, and much safer for newbies

    • If it is not a mechanical mod, it is almost certainly a regulated mod
    • They have internal circuitry to shut down the device in case of most battery problems

    What happened in this particular explosion?

    A man in Naples Florida was burned both externally and internally by an exploding battery. The lithium-ion 18650 battery was inside of his mechanical mod. He was vaping as normal - when it exploded.

    His sister found him not breathing, with a badly burned neck and face. The mouthpiece of the device possibly shot down his throat and exploded again (however this is not confirmed, just a possibility at this point.)

    This particular mod did not have any protective circuitry that could have prevented an accident like this.

    How can a vape shop teach about battery safety to prevent accidents?

    First, before selling a device the vape shop owner must clearly assess the level of expertise the end-user has. An unregulated device should only be sold to expert level users.

    A vape shop owner must use their own discretion when assessing the ability of and end-user. Some helpful questions to ask are:

    • How long have you been vaping?
    • Do you know the difference between a mechanical mod and a regulated mod?
    • What are some things that cause a battery to malfunction?
    • Do you know how serious a battery malfunction can be?

    After assessing the ability of the end-user, the vape owner should spend several minutes going over the details of battery safety. Spare no expense. This will not scare off your customers, it will do the opposite - create trust and a sense of authority for your shop. Preventing accidents should be any vape shop’s number one priority, always.
