Introduction
Lithium-ion batteries now power everything from smartphones and laptops to electric vehicles and energy storage systems. As demand surges across India, so does regulatory scrutiny. If you manufacture or import lithium-ion cells or battery packs for the Indian market, mandatory BIS CRS registration under IS 16046 is non-negotiable. This guide walks you through the entire process – what the standard covers, which products fall in scope, the documents you need, testing requirements, timelines, and costs – so you can achieve compliance without costly delays.
Why Lithium-Ion Battery BIS Certification Matters in 2025
Battery compliance has moved from a paperwork formality to a serious gatekeeping requirement. Four forces are driving the shift:
1. Safety Incidents
A rising number of fire and thermal-runaway incidents involving substandard lithium cells – in e-rickshaws, power banks, and consumer electronics – has pushed regulators to enforce stricter quality controls at the point of import and manufacture.
2. Market Size
India’s lithium-ion battery market is expanding rapidly on the back of EV adoption, renewable energy storage, and consumer electronics, making it one of the fastest-growing battery markets in the world. A larger market invites tighter oversight.
3. Enforcement Tightening
BIS and customs authorities are actively intercepting non-compliant battery shipments at ports. Goods without a valid CRS registration (R-number) are liable to be detained, returned, or destroyed.
4. Platform Requirements
Major e-commerce marketplaces and OEM buyers now require proof of BIS CRS registration before listing or onboarding battery products, effectively closing the market to uncertified suppliers.
What Is BIS CRS Registration?
BIS CRS (Compulsory Registration Scheme) is a mandatory certification administered by the Bureau of Indian Standards for products notified under the scheme. For lithium-ion batteries, key points include:
- Mandatory registration: Lithium-ion cells and battery packs notified under CRS cannot be manufactured, imported, stored, or sold in India without registration.
- Self-declaration based: Manufacturers register after their product is tested in a BIS-recognised laboratory against the relevant Indian Standard.
- Unique R-number: Each registered product receives a unique registration number that must be marked on the product and packaging.
- Standard mark: Registered products carry the BIS Standard Mark along with the R-number to demonstrate compliance.
- Foreign manufacturers welcome: Overseas manufacturers can register directly but must appoint an Authorised Indian Representative (AIR).
Indian Standard IS 16046: Scope and Parts
IS 16046 is the Indian Standard governing the safety of secondary (rechargeable) lithium cells and batteries for portable applications. It is harmonised with international IEC standards and is organised into the following parts:
| Part | Title / Scope | Application |
|---|---|---|
| IS 16046 (Part 1) | Secondary lithium cells and batteries for portable applications – General safety requirements | Cells and batteries used in portable equipment |
| IS 16046 (Part 2) | Secondary lithium-ion cells and batteries for portable applications | Lithium-ion cells and battery packs for portable devices |
| IS 16046 (Part 3) | Coin / button secondary lithium cells and batteries | Small coin and button format rechargeable lithium cells |
Which Battery Products Require CRS Registration?
Covered Products
- Sealed secondary lithium-ion cells (cylindrical, prismatic, pouch)
- Lithium-ion battery packs for portable applications
- Batteries used in laptops, tablets, and smartphones
- Power banks and portable chargers
- Batteries for portable electronic and IT equipment
Not Covered (Check Latest Notifications)
- Large stationary energy storage systems (governed under separate standards)
- High-voltage EV traction battery packs (covered under AIS / separate EV standards)
- Primary (non-rechargeable) batteries
- Products explicitly exempted in the relevant CRS notification
Note: The list of notified products is periodically updated by BIS. Always verify the current CRS notification applicable to your specific product before applying.
BIS CRS vs. BIS ISI for Batteries
Manufacturers often confuse the two BIS schemes. The applicable scheme depends on the battery type and the governing standard:
| Battery Type | Standard | Scheme | Marking |
|---|---|---|---|
| Lithium-ion cells / packs (portable) | IS 16046 | CRS | Standard Mark + R-number |
| Coin / button lithium cells | IS 16046 (Part 3) | CRS | Standard Mark + R-number |
| Lead-acid / certain other batteries | Relevant IS | ISI | ISI Mark + Licence number |
| Battery chargers / adapters | IS 13252 | CRS | Standard Mark + R-number |
Step-by-Step BIS CRS Registration Process for Batteries
- Identify the applicable standard: Confirm that your lithium-ion product falls under IS 16046 and the relevant CRS notification.
- Appoint an AIR (foreign manufacturers): Overseas manufacturers must nominate an Authorised Indian Representative who is liable in India.
- Create a BIS portal account: Register on the BIS Manak Online portal and prepare the manufacturer and product details.
- Draw test samples: Select representative samples of the cell or battery pack for testing as per the standard.
- Test in a BIS-recognised lab: Submit samples to a BIS-recognised laboratory; testing covers electrical, mechanical, environmental, and safety parameters under IS 16046.
- Submit the application: File the online application with the test report, documents, and fees through the BIS portal.
- Receive the R-number: Once BIS reviews and approves the application, a unique registration (R-) number is granted, after which you may mark and sell the product.
Documents Required for IS 16046 CRS Registration
For Indian Manufacturers
- Business registration / incorporation documents
- Factory / manufacturing licence

Frequently Asked Questions
1. Is BIS CRS registration mandatory for all lithium-ion batteries in India?
BIS CRS registration under IS 16046 is mandatory for lithium-ion cells and battery packs notified under the Compulsory Registration Scheme. You must confirm whether your specific product appears in the current CRS notification, but for most portable lithium-ion cells and packs it is compulsory.
2. Can a foreign manufacturer apply for BIS CRS directly?
Yes. Foreign manufacturers can apply directly under CRS, but they must appoint an Authorised Indian Representative (AIR) who is responsible and liable for compliance within India.
3. How long is a BIS CRS registration valid?
A CRS registration is granted for a fixed period and must be renewed before expiry to keep manufacturing, importing, and selling the product legally in India.
4. What is the difference between the R-number and the ISI mark?
The R-number is issued under the Compulsory Registration Scheme (CRS) and is used for products like lithium-ion batteries under IS 16046. The ISI mark is issued under the separate ISI licensing scheme for other notified products. Lithium-ion batteries use the CRS R-number, not the ISI mark.
5. What happens if I import lithium-ion batteries without BIS CRS registration?
Importing notified lithium-ion batteries without valid CRS registration is illegal. Shipments can be detained or rejected at customs, goods may be confiscated or destroyed, and penalties may apply under the BIS Act.
Conclusion
BIS CRS registration under IS 16046 is the gateway to selling lithium-ion batteries in India legally and safely. With enforcement tightening and marketplace requirements becoming stricter, early compliance protects your shipments, your brand, and your access to one of the world’s fastest-growing battery markets. By understanding the standard, preparing the right documents, and planning for testing timelines, manufacturers and importers can secure their R-number with minimal friction.
