GB 31241-2022 is a mandatory national standard in China, the full name of the \"Lithium-ion batteries and battery packs for portable electronic products Safety Technical Specification.\" The standard was originally published in 2014 and was revised in 2022 to be released as GB 31241-2022, replacing the older version. The standard is designed to ensure the safety of lithium-ion batteries and battery packs used in portable electronic devices and covers a wide range of products such as laptops, mobile phones, Bluetooth headsets and more.

With the rapid development of electronic products market, polymer batteries have been more and more widely used because of their high energy density, lightweight and portable characteristics. However, the safety of battery transportation is also increasingly attracting the attention of national regulators. In order to ensure the safety of batteries during transport, the International Air Transport Association (IATA) stipulates that all lithium batteries must pass the United Nations Manual of Tests and Criteria, Part III, Section 38.3 (UN38.3) tests before transport. This article will detail the process, requirements and importance of polymer battery UN38.3 certification to help battery manufacturers better meet international standards and ensure safe product transportation.

With the popularity of electronic products and the rapid development of new energy technologies, polymer batteries have become the new darling of the market because of their high energy density, lightweight and high safety characteristics. However, in the face of increasingly strict market regulation and high consumer requirements for product safety, 3C certification of polymer batteries has become a threshold that battery manufacturers must cross.

As the global demand for clean energy continues to grow, lithium batteries, as the core component of the new energy field, are more and more widely used. However, there are certain safety risks in the transportation of lithium batteries, such as short circuit, overheating and even explosion risks. In order to ensure the safety of lithium batteries in international transport, the United Nations has formulated Section 38.3 of the Manual of Tests and Standards for the transport of dangerous goods (referred to as UN38.3), which puts forward strict requirements for the transport safety of lithium batteries.

In this era of ever-changing technology, wireless mechanical keyboard has become the first choice for many office workers and game enthusiasts because of its unique feel and convenient connection. However, to sell your product in the United States, the world\'s largest consumer market, you must first pass the Federal Communications Commission (FCC) certification, known as FCC ID certification.

With the continuous advancement of technology, desktop printers have become indispensable devices in the home and office. However, with its wide use comes higher requirements for environmental protection. In order to ensure that the use of hazardous substances in electrical and electronic equipment is limited, the European Union has introduced CE-RoHS certification. This article will explore why desktop printers need CE-RoHS certification and how to successfully obtain it.

Among the many components of a tablet computer, the battery is undoubtedly one of the most critical parts. It not only directly affects the battery life of the device, but also relates to the safety of the user. Therefore, it is important for tablet manufacturers to ensure the safety and quality of batteries. In the Chinese market, 3C certification (China\'s mandatory product certification) is an important standard that batteries must pass.

As a key component widely used in electronic devices, electric vehicles and energy storage systems, the safety and reliability of lithium batteries have attracted much attention. During the design and production process, lithium batteries need to undergo a series of rigorous tests to ensure their stability in a variety of use scenarios. Among them, the drop test is an important part of evaluating the mechanical strength and impact resistance of lithium batteries. However, whether all lithium batteries need to carry out a 1.2-meter drop test, there is no uniform answer to this question, and it needs to be judged according to the specific application scenario and product standards.
