IEC 62619 – Why It Matters for Lithium Batteries

IEC 62619 – Why It Matters for Lithium Batteries

What is IEC 62619?

IEC 62619 is an international safety standard: “Secondary cells and batteries containing alkaline or other non-acid electrolytes — Safety requirements for secondary lithium cells and batteries, for use in industrial applications.” In plain terms, it’s the global benchmark for safety in industrial and stationary lithium batteries used in energy storage, RVs, off-grid systems and similar applications.

What does it test?

• Overcharge & over-discharge tolerance
• Short-circuit behaviour
• Mechanical abuse (crush, shock, vibration)
• Thermal stability and fire resistance
• Protection circuits verified at cell & pack level

The goal is to confirm the battery won’t create a fire, explosion or other hazards under normal or abnormal conditions, and that it fails safely if something goes wrong (e.g. charger fault, internal short).

Why it’s important (especially in Australia)

• Safety & compliance confidence: While not mandatory for small consumer batteries, IEC 62619 is highly recognised for energy storage, RV and off-grid use.
• Insurance & liability: Installers and insurers increasingly look for IEC 62619 (alongside UN 38.3). It strengthens due diligence and risk management.
• Import legitimacy: Signals independent, international-standard testing rather than unverified imports.
• Marketing credibility: Differentiates premium products from low-spec alternatives.

Quick summary

Bottom line

If your battery is tested to IEC 62619, you can confidently state it meets a leading international safety benchmark. That’s a genuine advantage for installers, insurers and customers choosing a safe, reliable lithium solution.
