TESTING & SAFETY

IEC 62133-2 — Portable Lithium Safety

Safety requirements and tests for portable sealed secondary lithium cells and batteries under intended use and foreseeable misuse.

Portable lithium battery safety testing

When it matters

It matters when rechargeable lithium cells or batteries fall within portable application scope or a market references the standard.

Key considerations

  • Cells and assembled batteries are evaluated separately.
  • Electrical, mechanical and thermal requirements apply.
  • Cell evidence does not replace battery evaluation.

Project preparation

  • Freeze cell source and protection circuitry.
  • Prepare specifications, schematics, labels and instructions.
  • Confirm representative samples and sequence.

Freeze the evaluated battery configuration
