At ONETIME, we ensure that all our battery-powered products meet the highest safety and regulatory standards. This includes compliance with UN38.3 certification, a globally recognized safety requirement for lithium-ion batteries used in electronic devices.

What is UN38.3 Certification?

UN38.3 is an international standard for lithium battery safety. It ensures that batteries can be transported safely by air, sea, and land without the risk of fire, leakage, or explosion. This certification is required by airlines, couriers, and regulatory authorities worldwide.

Why It Matters

✅ Trusted by Logistics Providers – Meets safety standards set by IATA (International Air Transport Association), ICAO (International Civil Aviation Organization), and DOT (Department of Transportation).

How is UN38.3 Certification Achieved?

To receive this certification, our lithium-ion batteries pass eight critical tests, including:

🔹 Altitude Simulation – Ensures batteries remain safe at high altitudes.

🔹 Thermal Test – Withstands extreme temperature changes.

🔹 Vibration & Shock Tests – Ensures durability during transport.

🔹 Short Circuit & Overcharge Tests – Prevents overheating and failure.
