Full title and description

Secondary cells and batteries containing alkaline or other non-acid electrolytes — Safety requirements for portable sealed secondary cells, and for batteries made from them, for use in portable applications — Part 2: Lithium systems (IEC 62133-2:2017 amended by IEC 62133-2:2017/AMD1:2021 and corrected by IEC 62133-2:2017/AMD1:2021/COR1:2021). This consolidated notation indicates the original Part 2 edition published in 2017 together with Amendment 1 (2021) and Corrigendum 1 (2021).

Abstract

IEC 62133-2:2017 specifies safety requirements and type tests for portable sealed secondary lithium cells and batteries with non‑acid electrolytes, addressing safe operation under intended use and reasonably foreseeable misuse. The Part‑2 edition (lithium systems) separates lithium requirements from nickel systems (Part 1), includes coin/coin‑cell provisions, updated cell‑to‑battery assembly guidance, mechanical abuse tests (vibration/shock) and references to related technical reports. The document has been amended and corrected in 2021 to clarify and update certain test procedures and editorial points.

Scope

Applies to portable sealed secondary lithium cells and batteries (including packs) containing non‑acid electrolytes intended for portable applications. The standard defines design, information, marking and a type‑test program to verify safety under intended use and reasonably foreseeable misuse; it addresses hazards such as fire, explosion, leakage, venting and thermal runaway and sets criteria and procedures for electrical, thermal and mechanical abuse tests. Coin/coin‑cell specifics and assembly guidance for cells into battery packs are included.

Key topics and requirements

• Definition of scope, terms and safety‑related parameters for lithium secondary cells and batteries.
• General safety considerations for cell and battery construction, insulation and protection against single‑fault conditions.
• Type tests covering electrical abuse (external short circuit, overcharge, forced discharge), thermal abuse, mechanical abuse (crush, shock, vibration), forced internal short‑circuit and cycle preconditioning where applicable.
• Special provisions for coin/button cells (ingestion warnings, internal resistance criteria) and for assembly of cells into battery packs (mechanical protection, wiring, balancing and protective circuitry).
• Requirements for marking, documentation and information to manufacturers, assemblers and end users (safety labels, transport/packaging notes and instructions).
• Test sample sizes, acceptance criteria and reporting requirements; updates and clarifications included in AMD1 and COR1.

Typical use and users

Primary users are battery and cell manufacturers, battery pack assemblers, OEM product designers integrating lithium batteries into portable electronics, test laboratories and certification bodies performing conformity assessment, and safety/regulatory engineers preparing technical documentation and labels. The standard is used to demonstrate product safety for market access and to harmonize test methods for portable lithium systems.

Related standards

Closely related standards and guidance include IEC 62133‑1:2017 (Part 1 — nickel systems), IEC 62281 (safety of lithium cells and batteries during transport / UN 38.3 related testing), IEC 61960 (secondary lithium cells and batteries for portable applications) and technical reports such as IEC TR 62914 referenced in the Part 2 bibliography. National/adopted variants (EN/NEN/BS/ISO adoptions) implement the IEC requirements regionally.

FAQ

Q: What is this standard?

A: IEC 62133‑2:2017 (with Amendment 1:2021 and Corrigendum 1:2021) is the IEC safety standard that specifies requirements and type tests for portable sealed secondary lithium cells and batteries to ensure safe operation under intended use and reasonably foreseeable misuse.

Q: What does it cover?

A: It covers design considerations, required information and markings, and a comprehensive set of type tests (electrical, thermal and mechanical abuse tests, forced internal short‑circuit, coin‑cell specifics and battery‑assembly requirements) intended to reduce hazards such as fire, leakage, venting and explosion in portable applications.

Q: Who typically uses it?

A: Battery and cell manufacturers, pack assemblers, OEMs integrating batteries into products, test laboratories, certification bodies and safety/regulatory engineers. It supports conformity assessment and market access activities.

Q: Is it current or superseded?

A: The Part‑2 edition was published in 2017 and was amended and corrected in 2021; the IEC webstore shows the consolidated publication with stability (review) date toward 2026 at the time of publication, so users should check the IEC catalogue for any newer revisions after 2021.

Q: Is it part of a series?

A: Yes — IEC 62133 is split into parts: Part 1 (IEC 62133‑1:2017) covers nickel systems and Part 2 (this document) covers lithium systems; the series replaces the earlier combined IEC 62133:2012.

Q: What are the key keywords?

A: Lithium, li‑ion, secondary cells, portable batteries, safety testing, abuse tests, coin cells, battery assembly, marking, IEC 62133‑2.
