BIS Certification for Lithium-Ion Batteries and Sealed Secondary Batteries: A Complete Guide by EVTL India

With the rapid growth of electronic devices, electric vehicles, and renewable energy systems, lithium-ion batteries and other sealed secondary batteries have become essential components in modern technology. While their advantages are undeniable—high energy density, longer life cycles, and efficiency—they must also meet stringent safety and performance standards to ensure reliability and user safety.

To regulate this, the Bureau of Indian Standards (BIS) has made it mandatory for such batteries to be certified under its Compulsory Registration Scheme (CRS). In this article, we will explore everything you need to know about BIS Certification for Sealed Secondary Battery, the scope of IS 16046 (Part 2):2018, and how EVTL India, a leading BIS CRS Consultant, simplifies the certification journey for manufacturers and importers.

What is BIS Certification?

The Bureau of Indian Standards (BIS) is the national body that sets quality and safety standards for products sold in India. To ensure that products comply with Indian safety norms, BIS mandates certification under its CRS (Compulsory Registration Scheme) for a range of electronic and electrical goods.

For manufacturers or importers of lithium-ion and sealed secondary batteries, BIS Certification is mandatory to ensure their products are safe for use and free from hazards such as overheating, fire, or explosion.

BIS Certification for Sealed Secondary Batteries

A sealed secondary battery is a rechargeable battery that is sealed to prevent spillage or leakage of the electrolyte. These batteries are widely used in backup power supplies, emergency lights, portable devices, and more. Because of their wide application in safety-critical environments, it is essential that they meet strict safety requirements.

To ensure quality and safety, BIS Certification for Sealed Secondary Battery is required as per Indian Standard IS 16046 (Part 2):2018. This standard outlines safety requirements based on IEC 62133-2:2017, which is globally recognized for battery safety testing.

BIS Certification for Lithium-Ion Batteries

Lithium-ion (Li-ion) batteries are among the most widely used battery technologies today. From smartphones and laptops to electric vehicles and energy storage systems, Li-ion batteries power a broad spectrum of devices.

Given their critical importance—and the potential safety risks if not manufactured properly—BIS Certification for Lithium-Ion Battery is mandatory before such batteries can be marketed or sold in India. This ensures compliance with IS 16046 (Part 2):2018, which specifies safety requirements for secondary lithium cells and batteries containing alkaline or other non-acid electrolytes.

This certification applies to:

• Lithium-ion battery packs

• Cells used in battery modules

• Batteries used in electric vehicles

• Batteries for consumer electronics

BIS CRS for Lithium-Ion Battery: IS 16046 (Part 2):2018

Under the bis certification for Lethium-Ion Battery, manufacturers must comply with IS 16046 (Part 2):2018, which aligns with the international standard IEC 62133-2:2017. The standard focuses on:

• Mechanical safety

• Electrical safety

• Thermal safety

• Battery construction and assembly

• Short-circuit and overcharge protection

Compliance with this standard ensures that the batteries are resistant to explosion, leakage, and thermal runaway under typical and extreme operating conditions.

BIS Certification Process for Lithium-Ion and Sealed Secondary Batteries

The BIS certification process can be detailed and technical. Here's an overview of the steps involved:

1. Product Testing

The battery or cell must be tested at a BIS-recognized laboratory in India. Testing covers mechanical, electrical, and thermal performance according to IS 16046 (Part 2):2018.

2. Documentation

The following documents are generally required:

• Product test reports

• Business license of the manufacturer

• Factory address and layout

• Brand authorization (if applicable)

• Technical drawings and safety declarations

3. Online Application

Once the testing is complete and documents are ready, the application is submitted to BIS through their online portal.

4. Scrutiny and Inspection

BIS may request additional information or conduct a factory inspection depending on the product type and origin.

5. Grant of Certification

If the application meets all the requirements, BIS grants a registration number, allowing the manufacturer to use the BIS Standard Mark on the product.

Challenges in BIS Certification and the Role of a BIS CRS Consultant

The BIS registration process can be complex, involving coordination with labs, thorough documentation, and strict compliance with technical standards. Delays or rejections due to small errors can be costly for businesses looking to launch products quickly.

This is where a professional BIS CRS Consultant like EVTL India becomes invaluable.
