IEC 62619 is a safety standard for secondary lithium cells and batteries used in industrial applications. Stationary battery storage may fall within its scope. A report for cells alone does not establish that a complete battery pack, inverter-battery combination or installed energy-storage system has been tested to every applicable requirement.
Do not infer an Indian registration obligation, a fixed testing cost or a whole-system approval from the standard number alone.
What the standard covers
The full title is Secondary cells and batteries containing alkaline or other non-acid electrolytes: Safety requirements for secondary lithium cells and batteries, for use in industrial applications. It specifies requirements and tests for safe operation of such cells and batteries. Stationary uses named in the standard’s scope include uninterruptible power supplies, grid-connected energy storage, telecom and emergency power. Motive industrial uses such as forklifts, automated guided vehicles and marine vessels are also in scope. Road vehicles and consumer devices are not. Where another IEC standard sets conflicting conditions for a special application, that standard takes precedence, as the IEC 62660 series does for road vehicles.
Editions
| Edition | Published | Note |
|---|---|---|
| IEC 62619:2017 | 2017 | First edition covering industrial lithium cells and batteries |
| IEC 62619:2022 (Edition 2.0) | May 2022 | Replaces the 2017 edition; adds requirements for hazardous live parts, battery system design, electromagnetic compatibility and a procedure for propagation testing, and strengthens battery management functional-safety expectations |
Many certificates still reference the 2017 edition. Check which edition a report applies and whether the product was re-tested to the 2022 text if that is what your contract requires. Source: IEC 62619:2017 on the IEC webstore and the ANSI preview of Edition 2.0, checked 14 October 2026.
What does a certificate establish?
Look for the precise product named in the report: cell, module or battery pack. Check the model designation, rated electrical characteristics, standard edition, issuing body and any limitations. A distributor’s brochure mentioning “IEC 62619” is not a substitute for evidence covering the equipment you will install.
| Evidence to request | Why it matters |
|---|---|
| Cell or battery-pack test report | Identifies the tested product and applicable edition |
| Battery management system documentation | Explains operating limits and protection behaviour for the pack |
| Inverter compatibility statement | Confirms the proposed battery and inverter are supported together |
| Local regulatory or utility requirement | Establishes what documentation this Indian installation actually needs |
IEC 62619 does not replace an installation design, fire-safety review, electrical protection or the manufacturer’s operating instructions. The battery-sizing guide addresses usable capacity; the BMS guide covers communication and protection questions. Both matter when choosing a hybrid system.
The kinds of tests involved
The standard tests both cells and assembled batteries. Without reproducing its procedures, the categories include:
- Electrical abuse: external short circuit, overcharge and forced discharge.
- Mechanical abuse: impact or drop, and crush where applicable.
- Thermal abuse: exposure to elevated temperature.
- Internal short circuit behaviour at the cell level.
- Protection and management: whether the battery’s protective functions keep it within its safe operating limits.
- Propagation: in the 2022 edition, a test procedure for whether a thermal event in one cell spreads through the battery. See thermal runaway.
The acceptance criteria are about outcomes such as no fire or explosion within the tested conditions, not a promise about field performance or lifetime.

Chemistry and the standard
IEC 62619 is not specific to one chemistry. It applies to lithium cells and batteries in general, so a pack with LFP cells and one with NMC cells can both be tested against it. The test outcomes depend on the design, the cell format and the protection, not on a chemistry label alone, so do not read a chemistry name as proof of a result. The LFP versus NMC comparison covers the chemistry trade-offs separately.
Is IEC 62619 mandatory for a home solar battery in India?
Do not decide that from a generic glossary sentence. Indian conformity obligations depend on the product category, the current BIS order and the specific application. MNRE’s Solar Systems, Devices and Components Goods Order, 2025, notified on 27 January 2025, covers solar PV modules, inverters and storage batteries, and MNRE has issued draft guidelines for series approval of storage batteries under it. Ask the manufacturer or supplier for the exact Indian Standard and registration route claimed for the battery model, then have the project engineer check the current legal requirement. A test report to an international standard and a valid Indian registration are different pieces of evidence.
For procurement or compliance, confirm the current IEC edition and model-specific Indian conformity route with a qualified reviewer. Sources for the order: Mercom India on the draft series-approval guidelines and the MNRE ALMM page, checked 14 October 2026.
Where it shows up in solar storage
- Hybrid solar systems, where a lithium battery pack is paired with a hybrid inverter and its battery management system.
- Commercial backup and UPS installations.
- Telecom shelters and similar standby installations.
- Utility and commercial energy storage, where system-level standards apply on top.
For Qbits hybrid inverters, the battery pairing and supported chemistries come from the model’s documentation, and the hybrid inverter range lists the models. Check the exact model’s battery-compatibility information, since the public datasheets describe lead-acid or lithium subject to compatibility.
Common problems with certification evidence
- A cell-level report presented as proof about a whole pack or system.
- A certificate that refers to an older edition or to a different capacity or cell supplier.
- No battery management system documentation behind a claim of “IEC 62619 compliant.”
- A claim of “certified” with no document supplied.
- A mix of certified and uncertified packs on the same battery bus.
Best practices
- Ask for the report or certificate for the exact model and capacity.
- Check the standard edition, the issuing laboratory and the date.
- Ask for the BMS documentation and the supported inverter list.
- Confirm the Indian registration route separately from the IEC report.
- Follow the manufacturer’s installation, ventilation and operating limits for state of charge, depth of discharge and temperature (see battery SOC and battery DOD).
- Compare prices only between packs that come with the same evidence. The battery brand guide covers the market.
Common mistakes
- Treating the standard number as proof of safety without the report.
- Assuming a cell certificate covers the battery system.
- Citing an Indian standard number for stationary lithium storage without checking its scope.
- Calling a battery “ALMM approved.”
- Operating outside the pack’s rated charge, discharge or temperature limits.
Key takeaways
IEC 62619 is an international safety standard for industrial lithium cells and batteries, including stationary storage, in a 2017 and a 2022 edition. It is evidence about the tested product, not a system approval and not an Indian registration. Ask for the report for the exact model, check the edition, and confirm the Indian route separately.
