▍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.

Since May 1, 2022, CQC will adopt the latest revision of CQC11-464112-2015 Safety Certification Rules for Secondary Batteries and Battery Packs Used in Portable/Stationary Electronic Devices，which increases the certification requirements for lithium-ion batteries and battery packs for stationary electronic devices, as well as changes to the certification mode 2 and 3 certificate validity to 5 years.
Scope of application to increase the secondary batteries and batteries used in stationary electronic, including stationary information technology equipment (IT equipment), audio and video equipment (AV equipment), communication technology equipment (CT equipment), measurement control and laboratory electronic equipment and similar equipment. In addition, the uninterruptible power supply (UPS), emergency power supply (EPS) and other lithium-ion batteries and battery packs are also applicable to this implementation rule.
Change paragraph 4.2.1 Based on standards: The standard IEC 62133:2012, GB/T28164-2011 was deleted, and GB 40165-2021 Safety Certification Criteria for Lithium-ion Batteries and Battery Packs Used in Portable/Stationary Electronic Devices was added.
