In the current era of rapid technological development, polymer batteries, with their advantages of high energy density, light weight, and good safety performance, are widely used in various electronic products such as smart phones, laptops, and power tools, becoming an important \"energy heart\" that supports modern life. However, to ensure the quality and safety of such battery products, CCC certification has become a crucial step for them to enter the market.

In the current era of rapid technological development, lithium-ion batteries, with their advantages such as high energy density and long cycle life, are widely used in portable electronic products, electric vehicles, energy storage devices and other fields, becoming an indispensable part of modern life. However, with the rapid expansion of its market size, products of varying quality have flooded the market. Some inferior batteries have caused safety accidents such as fires and explosions, seriously threatening the lives and property of consumers. Against this backdrop, the CCC certification system for lithium-ion batteries emerged, aiming to regulate the market and ensure safety.

In the era of vigorous technological development, square batteries, with their unique advantages, have been widely applied in numerous fields. However, before entering the market, it must cross the crucial threshold of CCC certification. So, what exactly is CCC certification? What significance does it have for square batteries? Let\'s explore it in depth together.

In the current era of rapid technological development, pouch batteries, with their lightness, thinness, high energy density and good flexibility, are widely used in various electronic devices and have become an important force driving the development of the industry. However, as its application scenarios continue to expand, security issues have become increasingly prominent. To safeguard consumers\' rights and interests and regulate market order, the CCC certification for pouch batteries has emerged.

If a vacuum cleaner is to enter the South Korean market, the KC certification of the battery is an unavoidable threshold. This is a mandatory certification promoted by the Korea Institute of Standards and Technology (KATS), which focuses on the safety and electromagnetic compatibility of electronic and electrical products. As the battery of a vacuum cleaner is a portable lithium battery, it has been explicitly included in the scope of mandatory certification.

Why can the battery of a sweeper purchased online remain safe in complex environments when transported across regions? This is inseparable from UN38.3 certification. It originates from Article 38.3 of the United Nations Manual of Tests and Criteria for the Transport of Dangerous Goods and is a mandatory requirement for the air transportation of lithium batteries. After the 66th edition of the International Air Transport Association\'s (IATA) Dangerous Goods Regulations came into effect in 2025, restrictions were also imposed on the transportation capacity of lithium battery-containing equipment such as vacuum cleaners. This requirement will be officially enforced from 2026.

When selling smartwatches in the US market, FCC ID certification is an unavoidable topic. So, can smartwatches that do not have FCC ID certification be sold in the United States?

In the fields of consumer electronics and new energy, battery safety is an unavoidable topic, and the IEC 62133 report is precisely an important basis for measuring the safety of rechargeable batteries. This standard formulated by the International Electrotechnical Commission is not a single document but is divided into two parts, -1 and -2: -1 focuses on nickel-based batteries such as nickel-cadmium and nickel-metal-hydride, while -2 focuses on lithium-ion and lithium-polymer lithium-based batteries. In 2025, a new short-circuit burning duration test item was added, further raising the safety threshold.
