IEEE 1725 & 1625 Battery Certification: Standards for Rechargeable Batteries
The battery certification program aims to ensure that cellular goods meet the IEEE 1725 "Standard for Rechargeable Batteries for Cellular Telephones" or IEEE 1625 "Standard for Rechargeable Batteries for Multi-cell Mobile Computing Devices" standards, as well as other CTIA papers. It refers to the interaction of the entire mobile production chain (cell, rechargeable battery, external backup battery pack, mobile product (host), power adapter, and charging cradle). The project is a system-level certification process that includes subsystem identification, such as battery packs and adapters, and certification of entire cellular device systems that use recognized subsystems.
