Fire Prevention Month Reminder: Use Lithium-Ion Batteries with Care

They power nearly everything we rely on daily—from smartphones and laptops to electric scooters, earbuds, toys, and even our cars. Lithium-ion batteries have become essential in our homes, our pockets, and even our garages. But while these tiny powerhouses make life more convenient, they can also pose serious fire hazards if not handled with care.

As we observe Fire Prevention Month this October, experts are urging households to pay attention to these widely used—but often overlooked—energy sources.

Common, Convenient—and Risky

In a typical family home, there may be a dozen or more devices powered by lithium-ion batteries: tablets, laptops, cordless power tools, e-bikes, vacuum cleaners, Bluetooth speakers—the list goes on.

With so many in use, it’s not surprising that some will fail, often with dangerous consequences.

The U.S. Consumer Product Safety Commission (CPSC) documented over 25,000 incidents involving overheating or fires linked to lithium-ion batteries across more than 400 different products between 2013 and 2018. Experts agree that the actual number is likely much higher, since not all incidents are reported or tracked.

Meanwhile, data from PGH Batteries shows lithium-ion batteries were responsible for 18% of residential fires between 2009 and 2017, with many of these incidents caused by charging errors, physical damage, or poor disposal practices.

What Causes These Batteries to Fail?

Unlike traditional alkaline batteries, lithium-ion batteries store large amounts of energy in a small space. This makes them efficient, but also more vulnerable to thermal runaway—a rapid rise in temperature that can lead to fire or even explosion.

Common causes include:

• Manufacturing defects
• Overcharging
• Using damaged or low-quality chargers
• Punctures or crushing
• Exposure to high heat or moisture
• Improper disposal

Simple Steps to Stay Safe

While lithium-ion batteries are generally safe when used correctly, Fire Prevention Month is a perfect time to review best practices to reduce risks:

• Avoid physical damage: Never puncture, bend, or crush batteries. Even small cracks can cause internal short circuits.
• Use only the correct charger: Always stick to the charger recommended by the manufacturer. Off-brand or poorly made chargers can overheat batteries.
• Watch the temperature: Keep batteries out of extreme heat (above 140°F) or freezing cold (below -4°F). Ideal use and storage temperatures range from 32°F to 95°F.
• Prevent overcharging: Unplug devices once fully charged, and look for products with built-in Battery Management Systems (BMS) that regulate charging.
• Keep dry: Don’t expose batteries to water or high humidity. Moisture can lead to corrosion or dangerous short circuits.
• Store safely: If you’re storing a device for a while, keep the battery at 40–60% charge in a cool, dry place, away from sunlight or flammable items.
• Inspect often: If a battery looks swollen, feels hot, or gives off a strange odor, stop using the device immediately and dispose of it properly.
• Dispose responsibly: Never toss lithium-ion batteries in the trash. Take them to a certified recycling center or hazardous waste facility. Tape over the terminals to prevent accidental shorting during transport.

Why This Matters Now

As lithium-ion battery use continues to grow—especially with the rise of electric vehicles, e-bikes, and portable electronics—it’s more important than ever to treat them with care.

“Because these batteries are so common, we often forget how powerful they are,” said a local fire safety expert. “But with just a little more attention, we can prevent fires and protect our homes and families.”

So this Fire Prevention Month, take a closer look at the batteries in your home. A few smart habits could make all the difference.
