▍What is CTIA CERTIFICATION?

CTIA, the abbreviation of Cellular Telecommunications and Internet Association, is a non-profit civic organization established in 1984 for the purpose of guaranteeing benefit of operators, manufacturers and users. CTIA consists of all U.S. operators and manufacturers from mobile radio services, as well as from wireless data services and products. Supported by FCC (Federal Communications Commission) and Congress, CTIA performs a large part of duties and functions that were used to be conducted by the government. In 1991, CTIA created an unbiased, independent and centralized product evaluation and certification system for wireless industry. Under the system, all wireless products in consumer grade shall take compliance tests and those complying with the relevant standards will be granted to utilize CTIA marking and hit store shelves of North American communication market.

CATL (CTIA Authorized Testing Laboratory) represents labs accredited by CTIA for testing and review. Testing reports issued from CATL would be all approved by CTIA. While other testing reports and results from non-CATL will not be recognized or have no access to CTIA. CATL accredited by CTIA varies in industries and certifications. Only CATL which is qualified for battery compliance test and inspection has access to battery certification for compliance to  IEEE1725.

▍CTIA Battery Testing Standards

a) Certification Requirement for Battery system Compliance to IEEE1725— Applicable to Battery Systems with single cell or multiple cells connected in parallel;

b) Certification Requirement for Battery system Compliance to IEEE1625— Applicable to Battery Systems with multiple cells connected in parallel or in both parallel and series;

Warm tips: Select above certification standards properly for batteries used in mobile phones and computers. Do not misuse IEE1725 for batteries in mobile phones or IEEE1625 for batteries in computers.

▍Why MCM？

● Hard Technology: Since 2014, MCM has been attending battery pack conference held by CTIA in US annually, and is able to obtain latest update and understand new policy trends about CTIA in a more prompt, accurate and active way. 

●Qualification: MCM is CATL accredited by CTIA and is qualified to perform all processes related to certification including testing, factory audit and report uploading.

December 17, 2021，the State Administration for Market Regulation issued Beijing Xingda Zhilian Technology Co., LTD. ‘s recall of some lithium iron phosphate replacement batteries of Hello brand.  
In accordance with the requirements of the “consumer product recall management interim provisions”, Beijing Xingda Zhilian technology co., LTD., take the initiative to report to the state administration of market supervision and management of the recall plan, and as from today the recall of 60-5 lithium iron phosphate manufactured from February 17 to February 28,2021 will be involving the number to 5018.  
The reason for this recall is that the components on the battery protection plate may be damaged by the controller capacitor of the user’s modified car, which may cause the components to overheat. In extreme cases, there may be a safety risk of overheating and fire.
In November 2021, ICAO dangerous Goods Group proposed in the meeting: considering reducing the risk of transportation of lithium batteries, it is suggested to add 30% limit of SOC to the parts of packaging instructions PI967, PI966, PI974, PI910 and other parts of lithium batteries transported in accordance with UN 3481 and UN3171.
