What is the national standard battery capacity for cell phones now, the mAh.

Recently, the Ministry of Industry and Information Technology released the latest statistics, as of November, China's cell phone users have more than 842 million households. With the expansion of the cell phone industry, the number of users, and related to the safety of cell phone batteries and other accessories are increasingly concerned by users. But for the standard issue of cell phone battery testing, the industry also has a different argument, and therefore triggered several controversies.

The current "General Specification for Lithium-ion Batteries for Cellular Telephones" has been implemented since 2000. The relevant standards mainly refer to the relevant performance and characteristics of nickel-metal hydride and nickel-cadmium batteries. However, as cell phones become more and more powerful, the demand for battery capacity is also increasing, the industry began to generally use a larger capacity, longer life of lithium-ion batteries, nickel-metal hydride, nickel-cadmium batteries have basically withdrawn from the cell phone industry.

The current "General Specification for Lithium-ion Batteries for Cellular Telephones" stipulates that "the temperature standard for thermal shock test is 150 ℃ for 30 minutes". The current battery can not withstand 150 ℃ standard, especially more than 1000 mAh of large-capacity batteries can only pass the 130 ℃ test, so the industry for the 150 ℃ or 130 ℃ standard has been controversial for many years. 2007 Xiaxin because of the test standard is not uniform, and in the battery "thermal shock" test was

"I'm not sure if I'm going to be able to do that.

"In 2005, the AQSIQ had formulated a 'new national standard', which we apply in our daily testing. If the test is conducted according to this standard, there will be no unqualified problems." A person in charge of a domestic cell phone manufacturer who did not want to be named said. The reporter learned that the "new national standard" he referred to was put forward by the AQSIQ in 2005 in conjunction with the National Technical Committee for Standardization of Alkaline Storage Batteries, and although this standard has not been formally announced, a number of official testing organizations, including the Ministry of Industry and Information Technology's Terra Laboratories, have already been applying this standard to their product testing.

Similar to the standard of the battery, the battery can be used in a variety of ways.

Similarly, the problem of battery overcharging, the standard provides a single battery loading voltage of 10V, while the "new national standard" requires no less than 4.6V. industry development so far, lithium-ion batteries are commonly used in cell phones has been 10 years, and at present, more than 1,000 mAh capacity of the battery in the cell phone has been widely used, and with the growth in sales of consumers' smartphones, the battery has been widely used in the cell phone market. With the growth of smartphone sales, consumer demand for high-capacity batteries is also more robust. "The technical level is no longer a problem, but we call on the relevant state departments to convene enterprises to develop standards in line with the level of development and practicality of the industry, and introduce them as soon as possible. Don't cause misunderstanding between the market and consumers because the standard is not uniform and clear." The head of the above domestic cell phone manufacturers said
