Lithium-Ion Batteries are notified under the BIS Compulsory Registration Scheme (CRS) and must comply with IS 16046:2018 — the Indian Standard aligned with IEC 62133 — before they can be manufactured, imported, sold, or distributed in India. Registration is mandatory under the BIS Act, 2016 and requires completing 10 mandatory safety tests at a BIS-recognised laboratory, submitting a full document set including manufacturing facility and quality system documentation, and passing a potential BIS factory inspection. Foreign manufacturers must appoint an Authorised Indian Representative (AIR). Non-compliance can result in customs clearance refusal, seizure of goods, monetary penalties, and potential imprisonment.
Lithium-Ion Batteries sit at the intersection of global energy transition and everyday consumer convenience — they power electric vehicles, smartphones, laptops, power tools, medical devices, and grid-scale storage systems. Their ubiquity makes their safety properties a matter of serious public concern. Thermal runaway, overcharge incidents, and mechanical failure in lithium-ion cells are not theoretical risks — they have resulted in product recalls, fires, and consumer injuries globally. That is precisely why India's Bureau of Indian Standards has brought lithium-ion batteries firmly within the scope of mandatory certification through the Compulsory Registration Scheme.
For manufacturers and importers, BIS CRS registration is not optional and is not a procedural formality. It is the legal gate through which every lithium-ion battery must pass before it touches the Indian market. This guide provides the complete picture: the applicable standard, every mandatory test, the full document set, and the step-by-step path from product to certificate.

About the BIS Compulsory Registration Scheme
The Compulsory Registration Scheme (CRS) is a mandatory product certification framework established under the Bureau of Indian Standards Act, 2016. It requires that notified product categories conform to their applicable Indian Standard — through laboratory testing, documentation review, and manufacturing facility inspection — before they can be legally manufactured, imported, sold, or distributed in India.
The scheme exists because India's market, at scale, cannot rely on voluntary compliance to ensure that products meet minimum safety and quality thresholds. By mandating pre-market certification for categories with elevated safety risk — including electronics, electrical goods, IT products, chemicals, and batteries — BIS provides the regulatory infrastructure that protects both consumers and the credibility of the market itself.
Why BIS CRS Registration Matters for Lithium-Ion Batteries
BIS CRS registration for Lithium-Ion Batteries serves a purpose well beyond regulatory tick-boxing. Given the safety profile of lithium-ion chemistry — which carries real thermal, electrical, and mechanical hazard potential when cells or packs are substandard — the consequences of uncertified batteries entering Indian commerce extend to consumers, businesses, and downstream industries that depend on these cells as a power source.
IS 16046:2018 mandates safety tests specifically designed to verify that Lithium-Ion Batteries do not present fire, explosion, or electrical hazard risks to end users — whether in smartphones, EVs, laptops, or energy storage systems. BIS registration is the mechanism that verifies this compliance at scale.
Without a valid BIS CRS registration, Lithium-Ion Batteries cannot legally be sold, distributed, or imported into India. Customs clearance is contingent on registration, and retailers and industrial buyers increasingly require the IS mark as a procurement condition — making registration a commercial necessity alongside a legal one.
The registration process — particularly the factory inspection and quality management system documentation requirements — drives manufacturing discipline that produces more consistent, reliable battery performance across production batches. This benefits not just buyers but the manufacturer's own brand reputation and after-sales cost base.
The IS mark displayed on BIS-registered Lithium-Ion Batteries is a credible, independently verified signal of quality and safety compliance. In procurement contexts — from OEM battery sourcing to EV component supply chains — BIS registration reduces due-diligence burden and strengthens the supplier's market position.
Applicable Standard: IS 16046:2018
IS 16046:2018 is the Indian Standard governing secondary lithium cells and batteries used in portable applications. It is aligned with IEC 62133 — the internationally recognised standard for lithium-ion battery safety — and specifies the safety requirements and testing methods that all covered cells and battery packs must demonstrate compliance with before BIS CRS registration can be granted.
IS 16046:2018 specifies electrical safety parameters covering charging behaviour, discharge performance, and protection against overcharge and forced discharge scenarios — the electrical fault conditions most likely to result in thermal or fire events in lithium-ion cells.
The standard establishes mechanical safety requirements verified through crushing and vibration tests, assessing the battery's structural integrity under the compressive and vibrational forces it may encounter during transport, installation, and operational use.
IS 16046:2018 includes environmental test parameters — low-pressure simulation and temperature cycling — that verify battery safety and integrity across the atmospheric and thermal conditions the battery will experience across its supply chain and operational life.
Because IS 16046:2018 is technically aligned with IEC 62133, manufacturers who have already conducted IEC 62133 testing for other markets may find significant overlap with the IS 16046:2018 test suite — though BIS-recognised laboratory reports remain a mandatory requirement for the Indian registration process.
10 Mandatory Safety Tests Under IS 16046:2018
BIS CRS registration for Lithium-Ion Batteries requires passing all ten prescribed safety tests at a BIS-approved laboratory. Each test targets a specific failure mode or hazard scenario relevant to real-world battery use. Understanding what each test assesses — not just its name — helps manufacturers prepare products that will pass first time rather than requiring redesign after a test failure.
Applies controlled compressive force to the battery cell to verify it does not catch fire or explode under physical stress — representative of real-world impact, compression, or crush scenarios the battery may encounter during transport or use.
Tests battery safety when installed with reversed polarity or in the wrong orientation — a realistic user-error scenario in consumer applications where misinstallation risk is non-trivial and the resulting electrical hazard could be severe without adequate protection design.
Simulates the reduced atmospheric pressure of air cargo holds to verify that the battery does not leak, vent, or present a fire or explosion hazard when transported by air — critical for products whose supply chains involve international air freight.
Drives the battery beyond its normal discharge endpoint to assess its behaviour under this fault condition — verifying that the cell does not enter thermal runaway, catch fire, or explode when subjected to forced deep discharge as might occur in a multi-cell series configuration with cell imbalance.
Charges the battery beyond its rated maximum voltage to verify that the protection circuitry and cell chemistry prevent catastrophic thermal events — the overcharge condition being one of the most common causes of lithium-ion fire incidents in real-world consumer use.
Tests battery performance through standard charge and discharge cycles, confirming stable capacity, consistent electrical performance, and the absence of safety anomalies over repeated cycling — providing assurance of both performance and operational safety across the battery's expected use life.
Evaluates battery behaviour under prolonged charging beyond full charge — the condition experienced in always-plugged-in consumer devices — verifying that the protection mechanisms prevent overcharge hazards during extended plug-in use without user intervention.
Measures the electrical insulation properties between live conductors and the battery's outer casing, ensuring adequate isolation that prevents shock hazards to users during handling and prevents unintended current paths within the device the battery powers.
Subjects the battery to sustained vibration across defined frequencies and durations to assess structural and electrical integrity under the mechanical stress of transportation and end-use environments — relevant for batteries used in vehicles, power tools, and industrial equipment.
Subjects the battery to repeated temperature fluctuations across a defined high-to-low range, verifying that thermal expansion, contraction, and cycling stress do not compromise cell casing integrity, electrolyte containment, or electrical performance — critical for batteries used across diverse climate conditions.

7-Step BIS CRS Registration Process for Lithium-Ion Batteries
Obtaining BIS CRS registration for Lithium-Ion Batteries follows a seven-step process from initial compliance confirmation through to certificate issuance. Each step builds on the previous one, and the overall timeline is determined primarily by the laboratory testing phase.
Review the specifications of your Lithium-Ion Battery product against IS 16046:2018 requirements. Identify and address any non-compliance issues — in design, chemistry, protection circuitry, or labelling — before submitting for laboratory testing, to avoid failing tests and incurring retesting costs and delays.
Register on the BIS portal and complete the CRS application form with accurate product model, brand, manufacturing facility, and company information. The application form must be consistent with all supporting documentation — inconsistencies are a common cause of review delays.
Arrange for representative samples of your Lithium-Ion Battery to be submitted to a BIS-recognised laboratory for all 10 mandatory safety tests under IS 16046:2018. Select the laboratory early and confirm test turnaround timelines before finalising your registration schedule.
Receive the complete set of test reports from the BIS-approved laboratory confirming IS 16046:2018 compliance across all 10 required tests. Review the reports carefully for completeness and accuracy before incorporating them into the application submission.
Pay the applicable fees for testing and BIS CRS registration processing. Retain payment receipts as part of your complete application record and ensure fee payment is reflected correctly in the portal before submitting the full application.
BIS may inspect the manufacturing facility to verify that quality management practices and production processes align with the declared standards and the test reports submitted. Preparing the facility team, quality documentation, and production records in advance reduces the risk of inspection findings that delay certificate issuance.
Upon successful review of the application, test reports, and factory inspection findings, BIS issues the CRS registration certificate for the Lithium-Ion Battery, authorising its manufacture, import, sale, or distribution in India under the registered brand and product details.
Consequences of Non-Compliance
Operating in the Indian market with Lithium-Ion Batteries that do not hold valid BIS CRS registration is an offence under the BIS Act, 2016 — and the consequences extend well beyond a regulatory notice. The practical and legal exposure for non-compliant manufacturers and importers is significant.
Lithium-Ion Battery consignments without valid BIS CRS registration are liable to be refused clearance at Indian ports and airports. This results in held goods, demurrage costs, and the commercial disruption of delayed or cancelled supply to customers — with no straightforward resolution short of obtaining registration.
BIS and enforcement authorities have the power to seize non-compliant products found in the market. Seizure of inventory — whether at the border, in a warehouse, or in the trade channel — represents a direct financial loss and potential supply disruption to downstream customers.
The BIS Act, 2016 prescribes monetary penalties for manufacturing, importing, or selling products without the required BIS registration. Penalties increase for repeat violations and wilful non-compliance, and can be assessed against individuals as well as legal entities.
For serious, repeated, or deliberately wilful non-compliance with BIS CRS requirements, the BIS Act, 2016 provides for imprisonment of responsible persons — making the personal liability dimension of non-compliance a material risk for directors, proprietors, and authorised signatories.

Frequently Asked Questions
Does BIS CRS registration cover lithium-ion battery packs as well as individual cells?
IS 16046:2018 covers secondary lithium cells and batteries for portable applications — which encompasses both individual cells and assembled battery packs. The exact scope of what must be registered and tested should be confirmed based on the specific product configuration you are manufacturing or importing, as a cell and the pack built from it may have separate registration requirements. Your BIS consultant can confirm the applicable registration scope for your specific product configuration.
Can a foreign manufacturer obtain BIS CRS registration for Lithium-Ion Batteries directly?
Yes. Foreign manufacturers can obtain BIS CRS registration for Lithium-Ion Batteries destined for the Indian market, but they must appoint an Authorised Indian Representative (AIR) to act as the regulatory liaison with BIS throughout the registration and ongoing compliance process. The AIR can be the importer, a group entity, or an independent regulatory consultant. The registration is held in the name of the foreign manufacturer with the AIR's details on record with BIS.
How long does BIS CRS registration for Lithium-Ion Batteries typically take?
The overall timeline typically ranges from 8 to 16 weeks, with the laboratory testing phase being the primary determinant of the total duration. Initiating sample testing at a BIS-recognised laboratory as early as possible — ideally before other application documentation is fully compiled — is the most effective way to shorten the overall registration timeline.
Does the BIS CRS registration for Lithium-Ion Batteries need to be renewed?
BIS CRS registrations require periodic renewal to remain valid. BIS may also conduct market surveillance between renewal cycles to verify continued compliance with the registered specifications. Maintaining a compliance calendar with upcoming renewal dates helps ensure ongoing market access is not disrupted by a lapsed registration.
