Lithium-Ion Battery Fire: How Do You Put Out a Lithium-Ion Battery Fire?

Lithium-ion batteries power our daily lives, from smartphones to electric cars and even boats. However, the risk of a lithium-ion battery fire is real and can be dangerous. So, how do you put out a lithium-ion battery fire? This comprehensive guide covers everything from the fire hazards these batteries pose to effective suppression methods and the appropriate fire extinguishers to use.

Why Do Lithium-Ion Batteries Catch Fire?

Lithium-ion batteries catch fire primarily due to thermal runaway—a self-sustaining reaction that occurs when the battery overheats. Several factors can trigger thermal runaway, including:

  • Overcharging: Exceeding the battery’s voltage limit.
  • Physical Damage: Puncturing or crushing the battery.
  • Manufacturing Defects: Flaws in the battery’s construction.
  • Short Circuit: Internal or external faults causing excessive current flow.

The Hazard of Lithium-Ion Battery Fires

Lithium-ion battery fires are particularly hazardous for several reasons:

  • High Heat: These fires can reach temperatures exceeding 1000°F (537°C).
  • Toxic Fumes: Burning lithium batteries release toxic gases like hydrogen fluoride.
  • Explosions: The battery can explode if the internal pressure builds up too much.

How to Put Out a Lithium-Ion Battery Fire?

Fighting a lithium-ion battery fire requires specific techniques and tools. Here’s a step-by-step guide:

Step-by-Step Guide to Fighting Lithium-Ion Battery Fires

  1. Identify the Fire: Ensure it is indeed a lithium-ion battery fire.
  2. Evacuate the Area: Prioritize safety by evacuating people from the vicinity.
  3. Cut Off Power: If safe, disconnect the power source to prevent further damage.
  4. Use the Right Extinguisher: Employ a Class D fire extinguisher designed for metal fires.

What Type of Fire Extinguisher for Lithium-Ion Batteries?

  • Class D Extinguishers: These are specifically designed for metal fires and contain agents like dry powder.
  • Lithium Battery Fire Extinguishers: These often contain a combination of dry powder and other chemicals to suppress lithium battery fires effectively.

Lithium-Ion Battery Fire Suppression Methods

  • Water Mist: While water is typically not recommended, a fine mist can help cool the battery.
  • Dry Sand: Cover the battery with sand to smother the flames.
  • Fire-Resistant Blankets: Specially designed blankets can isolate the fire and reduce oxygen flow.

Lithium-Ion Battery Fire Scenarios

Lithium-Ion Battery Fire on a Boat

Fires on boats can be especially treacherous due to the confined space and potential for rapid spread.

  • Preparation: Have lithium battery fire suppression kits on board.
  • Immediate Action: Use a fire-resistant blanket and a Class D extinguisher.
  • Emergency Plans: Ensure all crew members know the emergency procedures.

Lithium-Ion Battery Fire in a Boat House

Boathouses store various flammable materials, increasing the risk of a severe fire.

  • Safety Protocols: Implement strict safety measures and regular inspections.
  • Fire Suppression Systems: Install automatic suppression systems designed for lithium fires.
  • Training: Conduct regular fire drills focusing on lithium battery fires.

Tools and Accessories for Lithium-Ion Battery Fire Fighting

  • Portable and Convenient: Ideal for travel and home use.
  • Effective Containment: Made of fire-resistant materials that can withstand high temperatures.

First Alert Smoke Fire Alarm with Long Life Lithium Battery

Early detection is crucial in preventing lithium-ion battery fires from escalating.

  • Long-Lasting Power: Equipped with long-life lithium batteries for reliable performance.
  • Early Warning: Provides timely alerts to ensure swift action.

Lithium-Ion Battery Disposal Fires

Improper disposal of lithium-ion batteries can lead to fires at recycling facilities and landfills.

  • Safe Disposal: Follow local regulations for battery disposal.
  • Recycling Programs: Utilize authorized recycling programs to handle battery waste.
  • Fire Prevention: Use disposal containers specifically designed for lithium batteries.

FAQs About Lithium-Ion Battery Fires

How Do You Put Out a Lithium-Ion Battery Fire?

Use a Class D fire extinguisher, water mist, dry sand, or fire-resistant blankets to extinguish the fire.

What Type of Fire Extinguisher is Best for Lithium-Ion Batteries?

Class D fire extinguishers are best suited for lithium-ion battery fires.

Why Do Lithium-Ion Batteries Catch Fire?

Thermal runaway, overcharging, physical damage, manufacturing defects, and short circuits can cause lithium-ion batteries to catch fire.

Can You Use Water to Put Out a Lithium-Ion Battery Fire?

While water is generally not recommended, a fine water mist can help cool the battery and prevent thermal runaway.


Lithium-ion batteries are integral to modern life, but they come with fire hazards that require careful handling and specific suppression methods. Knowing how to put out a lithium-ion battery fire can prevent small incidents from becoming disasters. From using the right fire extinguisher to understanding the unique risks on boats and boathouses, being prepared is key to safety.
