Lithium-ion batteries are a part of everyday life, they power our phones, laptops, e-scooters, e-bikes, power tools, and even some household appliances. But while these rechargeable batteries are generally safe when used correctly, they also come with a serious fire risk when damaged, overcharged, or improperly stored.
What Is a Lithium-ion Battery Fire?
Lithium-ion battery fires are different from other types of fires. When a battery overheats or is physically damaged, it can enter a dangerous state called thermal runaway. This causes the battery to rapidly heat up, vent toxic gases, and in some cases, explode or catch fire. Once ignited, lithium-ion fires burn extremely hot and can be very difficult to extinguish using standard fire extinguishers.
Why Are Lithium-ion Fires So Dangerous?
They escalate quickly – Fires can go from a small puff of smoke to a full-blown blaze in seconds.
They release toxic gases – Including carbon monoxide, hydrogen fluoride, and other harmful chemicals.
They can reignite – Even after appearing to be out, damaged batteries can reignite minutes or hours later.
What Should You Do If a Lithium-ion Battery Catches Fire?
Our advice is simple and clear:
Do NOT try to extinguish the fire yourself – Lithium-ion fires are unpredictable and dangerous. Attempting to put them out can put you at greater risk.
Evacuate the area immediately – Alert anyone nearby and exit the building or space calmly and quickly.
Call 111 – Report the fire to emergency services as soon as you are in a safe location.
Let the professionals handle it. Firefighters are trained and equipped to deal with these types of fires safely.
Tips to Help Prevent Lithium-ion Battery Fires
You can reduce the risk of lithium-ion battery fires by following these safety tips:
Buy from reputable brands and suppliers
Cheap or counterfeit batteries and chargers are more likely to fail or overheat.
Use the right charger
Always use the charger that came with the device or one recommended by the manufacturer.
Don’t overcharge
Unplug devices once fully charged. Avoid charging overnight or while you’re not at home.
Charge in a safe area
Place devices on a hard, flat surface while charging. Avoid charging on beds, couches, or under pillows where heat can’t escape.
Keep batteries out of the heat
Avoid leaving devices in direct sunlight or hot vehicles.
Watch for signs of damage
If a battery is swelling, leaking, overheating, or has a strange smell, stop using it immediately and safely dispose of it.
Store and dispose of correctly
Never throw lithium batteries in the rubbish. Use your local hazardous waste collection service or recycling centre.
Final Thoughts
As the use of lithium-ion batteries continues to grow, so too does the risk of related fires. Awareness, safe handling, and prompt action are key.
If a lithium-ion battery does catch fire -don’t try to be the hero. Evacuate and call 111.
