What is BIS Certification for Sealed Secondary Batteries?

BIS Certification for sealed secondary battery refers to mandatory registration under the Compulsory Registration Scheme (CRS) of BIS for rechargeable batteries that are sealed and designed for repeated charging and discharging. These batteries are widely used in:

• Mobile phones and laptops
• Power banks
• Bluetooth devices and wearables
• Electric vehicles (EVs)
• Energy storage and backup systems

Sealed secondary batteries, particularly lithium-ion batteries, pose safety risks such as overheating, fire, and explosion if not manufactured according to strict standards. Therefore, BIS certification ensures that only compliant and tested batteries are allowed in the Indian market.

BIS Certification of Lithium-Ion Battery: Why is it Necessary?

BIS Certification for Lithium-Ion Battery is compulsory before manufacturing, importing, selling, or distributing lithium-ion batteries in India. Lithium-ion batteries fall under the BIS CRS due to their widespread use and potential hazards.

Without BIS registration:

• Import consignments can be detained or rejected
• Products can be banned from sale
• Heavy penalties and legal action may be imposed
• Brand reputation can suffer irreversible damage

Obtaining BIS certification not only ensures legal compliance but also improves market acceptance, customer trust, and long term business sustainability.

BIS CRS for Lithium-ion battery: Regulatory Framework Explained

BIS CRS for Lithium-Ion Battery operates under the Compulsory Registration Scheme introduced by the Ministry of Electronics and Information Technology (MeitY). Under this scheme, manufacturers must register their products with BIS based on successful testing from a BIS recognized laboratory.

Key features of BIS CRS for lithium-ion batteries include: 

• Product wise registration (each model requires separate approval)
• Factory specific registration (approval is linked to manufacturing location)
• Mandatory testing as per Indian Standards
• Ongoing compliance and surveillance by BIS

Once approved, the manufacturer is permitted to use the BIS Standard Mark with a unique Registration Number (R-Number).

Frequently Asked Questions (FAQ): BIS Certification for Sealed Secondary & Lithium-Ion Batteries  

1. Is BIS certification mandatory for sealed secondary batteries in India? 

Yes, BIS certification for sealed secondary battery products is mandatory in India. Rechargeable batteries, including lithium-ion batteries, must be registered under the BIS Compulsory Registration Scheme (CRS) before they can be manufactured, imported, or sold in the Indian market.

2. What standard applies to BIS certification for lithium-ion batteries?

The applicable Indian Standard for lithium-ion batteries is IS 16046 (Part 2):2018. This standard specifies safety requirements and testing methods for secondary lithium cells and batteries used in portable applications.

3. What is BIS CRS for Lithium-Ion Battery?

BIS CRS for Lithium-Ion Battery refers to the Compulsory Registration Scheme under which lithium-ion batteries must be tested at a BIS-recognized laboratory and registered with BIS before market entry. Each battery model and manufacturing location requires separate registration.

4. Who needs to apply for BIS certification for sealed secondary batteries?

Manufacturers located in India or abroad must apply for BIS certification. Foreign manufacturers are required to appoint an Authorized Indian Representative (AIR) to submit and manage the BIS CRS application on their behalf.

5. How long does BIS certification for Lithium-Ion Battery take?

The typical timeline for BIS certification for Lithium-Ion Battery is around 4 to 6 weeks, depending on product readiness, testing duration, and accuracy of documentation submitted to BIS.

6. What happens if lithium-ion batteries are sold without BIS certification?

Selling or importing lithium-ion batteries without BIS certification can result in product seizure, import rejection, monetary penalties, and legal action by regulatory authorities. Non-compliance may also lead to long-term damage to brand credibility.

7. Is BIS certification required for lithium-ion battery packs as well as cells?

Yes, BIS certification applies to both lithium-ion cells and lithium-ion battery packs. Even if certified cells are used, the assembled battery pack may still require separate BIS registration based on its configuration.
