IEEE 1725 and battery powered products

IEEE 1725 standard was developed for rechargeable lithium ion and lithium polymer batteries used in cellular devices. The standard establishes criteria for design analysis quality and reliability. The CTIA - the wireless association developed a battery certification program to verify the conformance of cellular devices to IEEE 1725. The CTIA program categorizes the cellular device as a host and its subsystems. The subsystems consist of the cell, battery pack and the adapter. This paper describes the CTIA certification process and how it applies to a lithium ion and lithium polymer rechargeable battery powered cellular product.
