CTIA Battery Certification Program

The CTIA Battery Certification Program verifies the conformance of applicable products, including lithium ion battery cells and packs, chargers and adapters, to IEEE Standard 1725TM1-2006, Standard for Rechargeable Batteries for Cellular Telephones and IEEE Standard 1625-2008, Standard for Rechargeable Batteries for Multi-Cell Mobile Computing Devices.

The certification process can be applied to single products, or to combinations of applicable products as a complete system, for example, a cell phone with its battery pack and charger together. In addition to testing, certification also requires an annual mandatory inspection of the manufacturing site. This is a quality audit, which will review critical cell process controls and manufacturing quality systems. A declaration of compliance with CTIA requirements is also required from the applicant.

A flowchart outlining the certification process can be seen here.

UL's dedicated service team will be happy to advise on the detailed procedure for your particular needs and product combination, or you can learn more online about our CTIA Battery Certification Service or browse our Frequently Asked Questions.
