LITHIUM-ION BATTERY SAFETY

Lithium-Ion Battery Safety in Everyday Life

Lithium-ion batteries have become an essential part of modern living, powering devices we rely on daily — smartphones, laptops, e-bikes, power tools, headphones, toys, and even vehicles. They’re efficient, powerful, and compact, making them ideal for today’s technology-driven lifestyle. But with that convenience comes an often-overlooked risk. When damaged, improperly charged, or stored unsafely, lithium-ion batteries can overheat, catch fire, or even explode.

Fire Prevention Week is October 5–11, 2025 this year, with the theme: 'Charge into Fire Safety™: Lithium-Ion Batteries in Your Home.' The goal is to help everyone understand the hidden dangers and take simple, effective steps to reduce risk.

Why These Batteries Can Be Hazardous
Lithium-ion batteries pack a large amount of energy into a small space. This makes them powerful but also sensitive to several factors:

· Physical damage – dropping a device, overusing tools, or improper handling.

· Overheating – charging in hot spaces like cars, under pillows, or near heat sources.

· Improper charging – using incompatible or low-quality chargers.

· Aging or defective cells – older or poorly manufactured batteries are more prone to failure.

A single damaged battery can quickly escalate into a dangerous situation, especially in enclosed spaces like homes, garages, or offices.

Everyday Devices We Don’t Think About
While many people associate battery fires with e-bikes or power tools, there are smaller, everyday devices that carry the same risk:

· Smartphones and tablets: Often left charging overnight or covered by bedding.

· Headphones and earbuds: Tiny batteries packed into small cases.

· Toys and gadgets: Children’s devices are often charged without supervision.

· E-bikes and scooters: Larger batteries require special care and outdoor charging.

· Smoke alarms and home safety devices: These also use lithium-ion batteries and must be handled correctly.

Safe Practices to Prevent Fires
Taking simple precautions can reduce the risk of lithium-ion battery fires:

· Buy Certified Products – Look for a certification mark from a nationally recognized testing laboratory.

· Charge Smart – Always charge on a hard, flat surface and unplug once fully charged.

· Use the Right Equipment – Stick to manufacturer-approved chargers and replace damaged cords immediately.

· Charge Larger Batteries Outdoors – E-bikes, scooters, and power tools should be charged in a flat, dry outdoor area.

· Recycle Responsibly – Never throw batteries in household trash; take them to certified recycling centers like Call2Recycle.org.

Recognizing Warning Signs
Stop using a battery or device immediately if you notice:

· An unusual odor

· Swelling or changes in shape

· Leaking fluids

· Excessive heat

· Odd noises or popping sounds

If it’s safe to do so, move the device away from flammable items and call 9-1-1.

Staying Ahead of the Risk
Lithium-ion batteries aren’t going away — they’re central to the way we live and work. By making informed choices and following basic safety steps, you can dramatically reduce the chances of a dangerous incident. We encourage all residents to check devices and charging practices to help keep our community safe.
