Tricky to handle

Lithium-based batteries power much of our modern life. They’re in our phones, tablets, laptops, tools, and vehicles. Compact and efficient, they store a large amount of energy in a small space — but that power also comes with risk. Understanding how to use and manage them safely helps prevent fires and injuries.

Community Safety Reminder

Lithium batteries are safe when handled correctly. The Minoa Fire Department encourages all residents to:

• Follow proper charging and storage practices.
• Recycle responsibly, but NEVER put batteries in your home recycling bin.
• Know the warning signs of a failing battery.

By taking simple precautions, you protect your home, your family, and your community.

Where Lithium Batteries Are Found

You'll find lithium-ion (rechargeable) and lithium metal (single-use) batteries nearly everywhere

• Rechargeable devices — Cell phones, laptops, power tools, and garden equipment
• Mobility equipment — E-bikes, scooters, and electric vehicles
• Everyday items — Cameras, smoke alarms, flashlights, and remote controls.

Because they’re so common, it’s easy to forget how much energy they contain. If damaged or overheated, that energy can release suddenly and violently.

Why Lithium Batteries Can Be Dangerous

Under normal use, lithium batteries are stable. Trouble begins when they’re overcharged, punctured, exposed to heat, or made with defects. These conditions can trigger thermal runaway — a chain reaction that causes overheating, fire, or even explosion. Once ignited, lithium fires burn extremely hot, release toxic gases, and may reignite after appearing to be out.

Safe Handling and Storage

Reduce risks by following these guidelines:

• Stop using any battery that’s swollen, cracked, leaking, or smells unusual. Here is info on such batteries from OCRRA, the Onondaga County Resource Recovery Agency: Damaged, Defective or Recalled (DDR).
• Use only the charger supplied or recommended by the manufacturer.
• Keep charging areas free of paper, cloth, and other combustibles.
• Store spare btteries in a cool, dry place away from sunlight and metal objects.
  • If metal of any kind touches the terminals, the battery can ignite; so, make sure batteries don't touch other batteries or other metal objects, say in your tool or junk drawer
  • Put batteries in individual bags or keep them in the blister packs that they come in from the store.
• Avoid dropping or crushing battery packs.
• Don't charge batteries near the exit to your home. A fire at that location could block your only exit.

Charging Tips

Charging is when most incidents occur. Always:

• Plug chargers directly into wall outlets, not extension cords or power strips.
• Charge in a well-ventilated area, away from flammable materials.
• Never charge overnight or unattended.
• Disconnect immediately if a battery or charger feels unusually hot.

What To Do With Batteries at End-of-life

Never place lithium batteries in household trash or recycling bins. When crushed or compacted, they can ignite and cause fires in trucks or facilities. Learn about proper battery management here from OCRRA, the Onondaga County Resource Recovery Agency: Battery Management.

When a Battery Catches Fire

If you see smoke or flames from a device:

• Evacuate immediately.
• Call 911.
• If safe, unplug the device and use a Class D or ABC extinguisher.
  • Remember that fire extinguishers are to be used only on tiny, confined fires; otherwise, evacuate immediately and call 911.
• Keep clear . Lithium fires can reignite and release hazardous fumes.
• Contact your fire department for guidance.
