On February 16, 2025 By newsroom Topic: Automotive

Lithium-ion batteries are a vital part of e-bikes and other modern devices, but improper use or care can lead to dangerous fires. The New York Fire Department (FDNY) shares critical safety tips to keep you safe while enjoying your e-bike.


Key Safety Tips for E-Bike Batteries

Buy From Reputable Brands
- Choose e-bikes and batteries from well-known manufacturers that comply with safety standards.
- Look for certification from independent testing labs like UL (Underwriters Laboratories).

Avoid Aftermarket Batteries
- Stick with batteries provided by the e-bike manufacturer.
- Aftermarket batteries often lack quality control and may be prone to overheating.

Inspect for Damage
- Regularly check the battery for signs of wear, swelling, or damage.
- If damaged, stop using it immediately and replace it.

Charge Safely
- Use the charger that comes with your e-bike, and avoid generic or third-party chargers.
- Charge in a cool, dry area away from flammable materials, and never charge unattended.

Don’t Overcharge
- Unplug the battery once it’s fully charged to prevent overheating.
- Avoid leaving it charging overnight.

Store Batteries Properly
- Keep batteries in a safe, dry place, away from heat sources and direct sunlight.
- Don’t store batteries in extremely hot or cold environments, like a garage or car.

Recycle Responsibly
- Never throw lithium-ion batteries in the trash; take them to a proper recycling facility.
- Many cities offer battery recycling programs to ensure safe disposal.


Why Fires Happen

  • Improper Charging: Using mismatched chargers or overcharging can lead to overheating.
  • Damaged Batteries: Physical damage or defects can cause short circuits.
  • Poor Quality: Low-cost, uncertified batteries may lack essential safety features.

E-Bike Fire Statistics

  • In NYC alone, 267 fires caused by lithium-ion batteries have resulted in 150 injuries and 18 deaths in 2023.
  • Fires are often linked to older or overused batteries in delivery bikes.

Pro Tip: Always prioritize quality and follow safety guidelines for all devices using lithium-ion batteries—not just e-bikes. Stay informed to ensure a safe and enjoyable experience!
