▍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.

IATA has officially released DGR 64th, which will be implemented on January 1, 2023. The following changes have been made to the lithium battery section of DGR 64th.3.9.2.6 (g): test summaries are no longer required for button cells installed in equipment.Addition Requirements-Section IA: addition of cells to the requirements for batteries over 12kg.Addition Requirements-Section IB: addition of 3m stacking test for packaging parts.Addition Requirements-Section II: the outer packaging needs to meet the requirements of 5.0.2.4, 5.0.2.6.1 and 5.0.2.12.1: when the battery and the equipment are packed separately and then packed in an outer packaging, a 1.2m drop test can be done on the packaging of the lithium battery or the whole package.Overpacks-Section II: newly added requirement: the packing elements are secured in a synthetic package and that the intended function of each package is not damaged.PI 967 & PI 970 (packaging instructions for lithium batteries installed in equipment).
Addition Requirements-Section I&II: the outer packaging of the equipment shall conform to the requirements of 5.0.2.4, 5.0.2.6.1, large equipment can be transported unpacked or on pallets if effective protection is providedOverpacks-Section II: newly added requirement: the packing elements are secured in a synthetic package and that the intended function of each package is not damaged.7.1.5.5.4 The operating label for lithium batteries no longer requires a contact number (shown below on the right). The operating label diagram for the DGR 63th is shown on the left and can continue to be used until December 31, 2026.
