The 10 Rules of E-Cig Battery Safety (Infographic)

All batteries can explode, and it can happen with electronic cigarette batteries.

Which is a shame, as every single incident we have heard of so far has been avoidable.

If you follow the correct safety procedures, e-cigarette battery explosions are very rare – about 1 in 10 million (source).

To enjoy vaping safely, follow the simple rules in this infographic (click the image for a larger version):

Further Information

Using the Right Charger

The number one cause of problems with electronic cigarettes is using the wrong charger.

In fact, at an ECITA meeting we were told it was the cause of every problem the group had come across. (This excludes mechanical mods, as these depends on user knowledge to operate safely. See The Vapers Guide to Voltage, Watts, and Ohms for more information.)

Use the charger supplied or recommended by your supplier to minimise problems.

Buy from a Reputable Supplier

Dodgy e-cigarette batteries are brought into the country and are generally sold on markets and by sole traders.

But batteries and chargers are not something you want to skimp on. Overcharge and over-discharge protection, ROHS certification and external battery testing all cost money, so it’s well worth being wary of cheap batteries and chargers.

There are plenty of reputable suppliers in the UK, and not all of them are members of ECITA – but if you see the ECITA logo you know that the supplier has to undergo testing and a twice yearly audit to ensure all products are as safe as possible.

Avoid Heat, Cold and Direct Sunlight

According to, extreme heat can lead to the resin in batteries melting and deforming, leading to electrolyte leakage and explosion. Avoiding storing your e-cig battery next to radiators/boilers or in direct sunlight.

Avoid Contact with Water

If your battery falls into or gets saturated with water, cease use. Either return it to the supplier or take it to a recycling station.

If you have a damaged battery, dispose of it correctly. If you’re not sure how, search for a hazardous waste disposal service near you.

Damaged Batteries

The same goes for damaged batteries – it’s just not worth the risk!

Avoid Carrying with Metal

Do not carry in a pocket with coins or keys.

Clean your Battery

The fire service recommends cleaning your e-cigarette battery weekly.

If you can’t manage that, do check your battery every now and again to see if any dirt or gunk has accumulated on your battery connection point. Use an alcohol wipe, cotton bud or tissue to gently clean gunk off.

Travelling with your Battery

By Plane 

Most airlines require you to place your battery in your cabin luggage. Before putting your ecig away, make sure you turn it off by pressing the button five times.

For more information, see our Guide to Travelling with E-Cigs.

If you have a device with a removable battery, most airlines recommend this should be installed in your device before being checked into hold luggage. Ideally, you would also tape over contact points with insulation tape.

When Abroad

Charging your e-cigarette abroad can prove tricky, as voltage supplied by power networks varies from country to country. The best option for charging your battery is to use the charger and plug recommended by your supplier, but with a plug adaptor bought in the country you are visiting. You can also check power supply before visiting a country on this Wikipedia page.

Ideally, you would also use surge protection, although in practice it’s not always practical to carry around a surge protection device.

  1. I forget how ignorant I am re; totally basic stuff such as charging batteries, having jammed any muni sub into any mod. I’ve been charging my Coolfire IV on a 2.4A adapter and just read it’s supposed to be on IA. Ouch! What could the consequence be? Death to mod? Or death by mod?
    Thanks for info – Becko

  2. Aaargh. I’ve only been vaping for a week – I got an Aspire et-s and an iStick20W for Christmas. It’s working out great so far, and your website has been really helpful (I’ll probably be leaving more comments on the relevant posts) but the atomiser blew on the second day, and now another one has blown, and I’ve only just checked the box and realised it has its own charger. I just assumed it was compatible with a phone charger and had used that. Unfortunately, although it came from a reputable UK supplier who was very helpful when my boyfriend was buying it for me as a present, the adapter comes with a US two-pin plug, so now I’ll have to buy one (well there’s probably one around the house… somewhere!) Anyway, that’s not a big deal, just slightly annoying, but you might like to draw people’s attention to that. Cheers for all the great advice so far.

  3. Hey there, how to clean batteries? i cannot remove batteries? i have IJUST S ELEAF , any words for that?
    Thank you
