This standard establishes criteria for design analysis for qualification, quality, and reliability of rechargeable lithium-ion (Li-Ion) and lithium-ion polymer (Li-Ion polymer) batteries for cellular telephone applications. Also included in the standard are: battery pack electrical and mechanical construction, packaging technologies, and pack and cell level charge and discharge controls and overall system considerations. The purpose of this standard is to ensure reliable user experience and operation of cell phone batteries. The battery and cellular telephone industries need standardized criteria for design and qualification of rechargeable battery systems and for verifying the quality and reliability of those batteries. Revision Standard - Superseded. Criteria for design analysis for qualification, quality, and reliability of rechargeable lithium ion and lithium ion polymer batteries for cellular telephone applications are established. Also included are: battery pack electrical and mechanical construction, packaging technologies, pack and cell level charge and discharge controls, and overall system considerations.
