Smart bracelets have long become a "little helper" for daily health management, and the built-in battery, as the core power source, directly affects the battery life and usage safety of the bracelet. Most of these batteries are lithium-ion batteries, which have high energy density and small size, making them suitable for the portability of smart bracelets. However, due to their chemical properties, they need to meet specific safety standards during transportation and use. The un38.3 certification is precisely the core safety certification for this type of lithium battery.

Why must the batteries of smart bracelets obtain un38.3 certification?
1. Transportation compliance bottom line: Mainstream transportation methods such as air and sea all make un38.3 certification a mandatory requirement for lithium battery transportation. Without certification, the battery may be refused shipment or detained.
2. Market access threshold: Both domestic and international e-commerce platforms and offline channels have strict reviews on smart bracelet products. The absence of un38.3 certification will affect the product's listing and sales.
3. Safety Trust Endorsement: Certification means that the battery has passed multiple rigorous tests such as short circuit, high temperature, and vibration, which can reduce usage risks and enhance consumer trust.
To apply for un38.3 certification, all these materials must be prepared
1. Basic product information: Detailed descriptions of the model, specification parameters, cell type, rated capacity, etc. of the smart bracelet battery.
2. Product samples: Sufficient and qualified samples (usually 30-50 pieces), which must be consistent with the mass-produced products.
3. Technical documents: Battery structure diagram, circuit diagram, factory inspection report, safety manual, etc.
4. Enterprise Qualifications: Copies of the business license, production license and other relevant qualifications of the applying enterprise.
