Why Vape Batteries Explode and What to Do to Prevent This

Vaping has become increasingly popular over the years as an alternative to smoking traditional cigarettes. However, there have been several reports of vape batteries exploding, causing injuries and property damage. While these incidents are rare, they can be quite dangerous.

Today, we will explore the reasons behind vape battery explosions and offer some tips on how to prevent them:

Why Do Vape Batteries Explode?

Vape batteries can explode for several reasons, but the most common cause is a phenomenon called "thermal runaway." This occurs when the temperature inside the battery rises rapidly, causing a chain reaction that results in the release of gas and heat. The pressure inside the battery builds up until it explodes. Several factors can contribute to thermal runaway, including:

1. Overcharging

Vape batteries can overheat if they are overcharged. This can happen if you use a charger that provides too much current or if you charge the battery for too long.

2. Short-Circuiting

A short circuit occurs when the positive and negative terminals of the battery come into contact with each other. This can happen if the battery is damaged or if it is not properly insulated.

3. Mechanical Damage

If a battery is punctured, crushed, or subjected to extreme temperatures, it can become damaged and more susceptible to thermal runaway.

4. Poor Quality Batteries

Low-quality batteries are more likely to experience thermal runaway. This is because they may not have the necessary safety features and may not be able to handle the high current levels required by vape devices.

How to Prevent Vape Battery Explosions

To minimise the risk of a vape battery explosion, follow these safety guidelines:

1. Use the Correct Charger

Always use the charger that comes with your vape device or one that is specifically designed for your battery type. This will ensure that your battery receives the appropriate amount of current during charging.

2. Don't Overcharge Your Batteries

Remove your batteries from the charger once they are fully charged. Overcharging can cause them to overheat, increasing the risk of thermal runaway.

3. Store Batteries Safely

Keep your batteries in a cool, dry place, away from direct sunlight or heat sources. Store them in a protective case to prevent them from coming into contact with metal objects that could cause a short circuit.

4. Inspect Your Batteries Regularly

Check your batteries for signs of damage, such as dents, punctures, or bulging. Replace any damaged batteries immediately.

5. Use High-Quality Batteries

Invest in reputable battery brands that have built-in safety features, such as vent holes and protection circuits. These features can help prevent thermal runaway.

6. Don't Mix and Match Batteries

Always use the same brand and model of battery in your vape device. Mixing different batteries can cause imbalances in voltage and current, which can lead to overheating.

7. Keep Your Device Clean

Regularly clean the battery contacts and terminals in your vape device to ensure a proper connection. This can help prevent short-circuiting.

8. Use Devices with Safety Features

Finally, choose vape devices that have built-in safety features, such as temperature controls and short-circuit protection. These can help prevent your batteries from overheating and exploding.


While vape battery explosions are rare, they can be dangerous if they do occur. By following the safety tips outlined in this post, you can significantly reduce the risk of experiencing a battery explosion. Always use high-quality batteries, keep your device clean, and store your batteries safely to ensure a safe and enjoyable vaping experience!
