Introduction to Lithium Battery Fires

Lithium batteries, due to their high energy density and flammability, can lead to fires if damaged, short-circuited, overcharged, or subjected to high temperatures. These fires can be more challenging to deal with than ordinary fires because lithium reacts explosively with water and produces toxic gases. Therefore, it's essential to know the correct way to extinguish such fires.

Steps to Put Out a Lithium Battery Fire

Here are the steps you need to follow to put out a lithium battery fire:

Ensure Safety: The first step in any emergency is to ensure the safety of all individuals present. Evacuate everyone from the area and call your local fire department immediately.

Use a Class D Fire Extinguisher: A Class D fire extinguisher is designed for use on flammable metal fires, including lithium. It effectively smothers the fire, preventing oxygen from fuelling it further.

Let it Cool Down: Once the fire is out, let the area cool down before you attempt to move anything. Lithium battery fires can re-ignite, so it's critical to ensure everything has cooled down completely.

WARNING: Never attempt to put out a lithium battery fire with water. Lithium reacts violently with water, causing a more significant fire or explosion.

Prevention is Better than Cure

Preventing lithium battery fires is always better than having to put one out. Here are some tips to prevent such fires:

Proper Storage: Store lithium batteries in a cool, dry place away from flammable materials.
Avoid Overcharging: Don't leave your devices charging unattended for extended periods. Overcharging can cause the lithium batteries to overheat and catch fire.
Inspect Regularly: Regularly inspect your lithium batteries for any signs of damage or bulging. If you notice anything unusual, replace the battery immediately.


Knowing how to put out a lithium battery fire is essential for everyone using devices powered by these batteries. Remember, safety should always be your first priority, and prevention is the best way to ensure it. By following the steps and tips highlighted in this guide, you can significantly reduce the risk of a lithium battery fire and know how to deal with one should it occur.

By creating awareness about this issue and sharing this information, we can make our homes and workplaces safer. Stay informed, stay safe!
