UN 38.3: This certification ensures lithium batteries can be safely transported by air, sea, or land. It includes tests for
altitude simulation, thermal cycling, vibration, shock, external short circuit, impact/crush, overcharge, and forced
discharge
CE Marking: Indicates compliance with European safety, health, and environmental requirements. While CE certification
covers electrical safety, it does not specifically address fire risks in lithium batteries.
For fire safety, lithium batteries must meet additional standards like UL 1642 (fire resistance) and IEC 62133 (electrical
safety).
What are the test items for UL1642 certification?
Overcharge Test: Evaluate the battery’s ability to withstand overcharging conditions without experiencing thermal
runaway or other safety hazards.
Overdischarge Test: Assesses the battery’s performance when subjected to prolonged discharge, ensuring it can safely
handle low voltage conditions without damage.
Short Circuit Test: Determines the battery’s response to a short circuit, verifying that it can safely handle high current
conditions without causing a fire or explosion.
Crush Test: Tests the battery’s resistance to mechanical abuse by applying a specified force to simulate crushing or
impact, ensuring it remains intact and does not rupture or leak.
Impact Test: Evaluate the battery’s ability to withstand impact forces, such as dropping or striking, without experiencing
damage or safety hazards.
Temperature Cycling Test: Subjects the battery to repeated cycles of temperature extremes to assess its thermal
stability and performance under varying environmental conditions.
Vibration Test: Measures the battery’s ability to withstand vibration and mechanical shock, simulating conditions
encountered during transportation or use in mobile devices.
Altitude Simulation Test: Determines the battery’s performance at different altitudes, ensuring it operates safely and
reliably under varying atmospheric pressure conditions.
External Short Circuit Test: Tests the battery’s response to an external short circuit, verifying that it can safely handle
such events without causing a safety hazard.
Mechanical Shock Test: Evaluates the battery’s resilience to mechanical shocks, such as dropping or impact, ensuring
it remains intact and functional.
· What is the difference between IEC 62133 and UN38.3?
IEC 62133 focuses on safety requirements for portable secondary lithium cells and batteries. At the same time, UN38.3 covers
testing procedures for lithium cells and batteries
Safety Tips
• Purchase and use devices that are listed by a qualified
testing laboratory.
• Always follow the manufacturer’s instructions.
• Only use the battery that is designed for the device.
• Put batteries in the device the right way.
• Only use the charging cord that came with the device.
• Do not charge a device under your pillow, on your bed, or
on a couch.
• Do not keep charging the device or device battery after it is
fully charged.
• Keep batteries at room temperature when possible. Do not
charge them at temperatures below 32°F (0°C) or above
105°F (40°C).
• Store batteries away from anything that can catch fire
