Vape-related fires, battery safety myths, and how to properly store your device

August 31, 2025

Vape-related fires make headlines, but the reality is less dramatic than it sounds. Most incidents are not caused by the devices themselves, but by user mistakes and battery misuse. As vaping continues to replace smoking across the UK, it is time to clear the air on battery myths and talk real safety, without the fearmongering.

Why do vape batteries fail?

Most vapes use lithium-ion batteries, just like phones, laptops and electric cars. When handled correctly, they are safe. But misuse, especially in cheap or counterfeit devices, can cause short circuits, overheating or thermal runaway, which leads to fires.

The most common causes of failure include:

Using the wrong charger or power source
Leaving devices in hot places like cars or direct sunlight
Carrying spare batteries loosely in a pocket or bag with keys or coins
Overcharging overnight or using damaged cables

In almost every fire-related incident reported in the UK, one or more of these factors were involved. These are preventable, not inherent to vaping itself.

The myth of exploding vapes

Media reports often use the word ‘explosion’ to describe battery failure, but this is misleading. Lithium batteries vent under pressure. That means they can rupture and cause heat or flames, not a Hollywood-style blast.

The term ‘exploding vape’ makes for a good headline, but it rarely reflects what actually happened. In nearly all cases, the incident involved poor-quality devices, mechanical mods with no safeguards or damaged batteries.

Safe charging: rules to live by

Use the charger that came with your device, or a branded equivalent
Never use frayed or mismatched cables
Unplug once fully charged, do not leave it overnight
Keep your device on a flat surface while charging, away from flammable materials

Also, avoid using random public USB sockets. Some are unregulated, and others might send the wrong voltage. At Vape Lounge UK, we stock certified chargers and accessories that meet safety standards.

How to store your vape safely

Storage is often overlooked, but it matters. A vape left in a hot car or shoved next to metal objects can become a hazard. Here is how to store it right:

Keep away from extreme heat or cold
Never carry spare batteries loose, use a plastic battery case
Store in an upright position to prevent leaking
Keep out of reach of children and pets

Our protective vape cases and storage kits are great for travel and everyday use.

How to spot a dodgy device

Counterfeit vapes often cut corners on battery safety. Warning signs include:

No CE or UKCA markings
Spelling errors or blurry packaging
Super low prices from unknown sellers
No clear information on battery specs

If in doubt, avoid it. Stick to trusted UK retailers like Vape Lounge UK and check for authentication codes on packaging when available.

When to replace your device or battery

Vapes are not meant to last forever. Replace the battery or device if you notice:

Shorter battery life than usual
Visible damage or warping
Overheating during normal use
Unusual smells or leaking

For safer upgrades, check our range of devices and coils, especially designed with user protection in mind.

Fire safety is common sense, not panic

The reality is this, most vape-related fires are completely avoidable. They are not random acts of danger, they are almost always linked to poor charging habits, counterfeit gear or storage neglect. Education, not panic, is what keeps vapers safe.

Take two minutes to check your charger, battery and device. That is all it takes to stay safe and keep vaping responsibly.
