IEEE Std 1625-2008, IEEE Standard for Rechargeable Batteries for Portable Computing, was approved on 26 September 2008. To purchase the standard, visit the IEEE shop.


This standard establishes criteria for design analysis for qualification, quality and reliability of rechargeable battery systems for portable computing. It also provides methods for quantifying the operational performance of these batteries and their associated management and control systems including considerations for end-user notification. This standard covers rechargeable battery systems for mobile computing. The battery technologies covered are limited to lithium ion and lithium ion polymer, but future versions of this document may include technologies that are not in general use at present. Also included are: battery pack electrical and mechanical construction; system, pack, and cell level charge and discharge controls; and battery status communications. The following are addressed: qualification process; manufacturing process control; energy capacity and demand management; levels of management and control in the battery systems; current and planned lithium-based battery chemistries, packaging technologies, and considerations for end-user notification.


The purpose of this standard is to ensure reliable user experience and operation of batteries in portable computing environments. The battery industries need standardized criteria for design and qualification of rechargeable battery systems and for verifying the quality and reliability of those batteries.
