Experts have created a new fire class just for batteries to help keep you and your home safe
What is a Class L fire?
In the past, we had five or six types of fires. In 2026, we have a new one. It is called Class L. This class is only for lithium-ion batteries.
These batteries are in almost everything we use. They are in your phone, your laptop, and your electric bike. Because these batteries burn in a special way, they need a special name.
Why Do We Need a New Category?
The Problem with Old Fire Classes
Before Class L, people used Class E (electrical) or Class AB extinguishers. These do not work well on batteries. A battery fire is not just an electrical fire. It is a chemical fire that creates its own heat.
How Lithium-Ion Batteries Burn Differently
When a battery breaks, it gets very hot. This is called thermal runaway. The battery keeps getting hotter and hotter. It can even explode. Even if the fire looks like it is out, it can start again hours later. This is why a new category was made.
What Does Class L Cover?
Class L covers any device that uses a lithium-ion battery. These are the things we use every day.
Common Devices in This Group:
- Smartphones and tablets.
- Laptops and power banks.
- E-bikes and E-scooters.
- Electric Cars (EVs).
- Vapes and cordless tools.
The Best Ways to Stop a Class L Fire
Why Water Isn’t Always Enough
Using a little bit of water on a battery fire is dangerous. It can cause a chemical reaction. To put out a battery fire, you need a huge amount of water to cool it down or a special chemical.
New Class L Fire Extinguishers
You can now buy Class L fire extinguishers. They often use a special liquid or agent. This agent stops the heat and coats the battery. This prevents the fire from starting again. Look for the Class L label on the bottle.
Safety Tips for Your Home and Office
You can prevent Class L fires by following these simple rules:
- Use the right charger: Only use the one that came with your device.
- Don’t overcharge: Take the plug out once the battery is at 100%.
- Keep it cool: Do not charge phones under your pillow or in the sun.
- Check for damage: If a battery looks puffy or leaks, stop using it.
- Charge in a safe spot: Do not charge e-bikes near your front door or exit.
Summary: The Future of Battery Safety
Class L is here to keep us safe. As we use more batteries, we must use the right tools to stop fires. Check your home and office for Class L extinguishers today.
