Overview
IEC 60086-2:2021 - "Primary batteries - Part 2: Physical and electrical specifications" is an international standard that defines the physical dimensions and electrical performance test conditions for standardized primary (non‑rechargeable) batteries. Applicable to primary batteries based on standardized electrochemical systems, this 14th edition (April 2021) includes the June 2022 corrigendum. The standard provides dimensional drawings, discharge test conditions and discharge performance requirements for a wide range of cell types and configurations.
Key topics and technical requirements
- Physical dimensions and symbols: Standardized drawings and symbols for multiple battery categories (Category 1 through 6) and many commercial designations (e.g., LR03, LR6, CR2032, 6F22) to ensure interchangeability and mechanical fit.
- Dimensional stability and gauges: Requirements and acceptance gauges for dimensional tolerances and fit (including P‑system/gauge opening dimensions).
- Discharge test conditions: Defined discharge regimes and environmental/test validity criteria used to evaluate battery performance under standard loads.
- Discharge performance requirements: Minimum acceptable electrical performance during specified discharge tests, allowing manufacturers and test labs to verify compliance.
- Specification tables and figures: Clear tabulation of battery specifications, dimensional drawings (Figures 1–31), and tables for gauge dimensions and application mapping.
- Supporting annexes: Informative annexes include tabulation by application, cross‑reference indices, common designations and a compliance checklist to simplify implementation and procurement.
Practical applications and who uses it
IEC 60086-2 is essential for stakeholders involved in design, production, testing and procurement of primary batteries and battery‑powered equipment:
- Battery manufacturers - ensure product dimensions and discharge performance meet international expectations and are interchangeable with industry-standard cells.
- Test laboratories and certification bodies - use the specified test methods and performance criteria for type testing and conformity assessment.
- Product designers and OEMs - specify correct battery sizes and performance for consumer electronics, medical devices, toys, remote controls and industrial sensors.
- Procurement and quality engineers - develop supplier specifications, acceptance criteria and incoming inspection procedures based on standard dimensions and test outcomes.
- Regulators and standards committees - reference the standard when defining product safety, labeling and interoperability requirements.
