Scope

Specifies criteria for design analysis and qualification of rechargeable Li‑ion and Li‑ion polymer batteries for mobile-phone host devices. Topics include battery and pack electrical/mechanical construction, packaging technology, cell- and pack-level charge/discharge control requirements, reliability and quality verification, and system-level considerations for safe and reliable handset operation. The standard is intended for manufacturers, integrators and test laboratories working with mobile handset battery systems.

Key topics and requirements

• Design and qualification criteria for Li‑ion and Li‑ion polymer cells and packs.
• Electrical and mechanical construction requirements for battery packs (connectors, interconnects, enclosure design).
• Pack- and cell-level charge and discharge control strategies, protection circuits and fault handling.
• Packaging technologies and mechanical integrity (drop, vibration, case stress considerations).
• Reliability, quality assurance, and recommended test methods for performance and safety validation.
• System-level considerations including thermal management, labeling/identification, and compatibility with host-device charging systems.

These topics summarize the principal technical coverage used to assess safety, reliability and performance of handset battery systems.

Typical use and users

Used by battery cell and pack manufacturers, mobile handset OEMs, accessory designers, test laboratories, certification bodies and compliance engineers to develop, validate and document battery designs for cellular handsets. The standard is also referenced by procurement and quality teams to set supplier requirements and acceptance criteria.

Related standards

Commonly used alongside other battery and product-safety standards, for example:

• IEEE 1625 (rechargeable batteries for multi-cell mobile computing devices / related IEEE battery standards).
• IEC 62133 (safety requirements and tests for portable secondary cells and batteries — Part 2: lithium systems) for cell/battery safety testing and certification.
• National/industry standards and test protocols (UL standards and regional product-safety standards) as applicable for end-product compliance.
