BIS for Lead-Acid Storage Batteries – Your Complete Guide

Lead-acid storage batteries are an essential component in various sectors including automotive, industrial, solar power systems, and uninterruptible power supplies (UPS). To ensure the quality and safety of these critical products, the Bureau of Indian Standards (BIS) has made it mandatory for manufacturers to comply with Indian standards. This blog explores everything you need to know about BIS certification for Lead-Acid Storage Batteries, its process, benefits, and the role of consultants in achieving compliance.

Why BIS Certification for Lead-Acid Storage Batteries Matters

The BIS certification for Lead-Acid Storage Batteries ensures that the batteries manufactured meet the required safety, performance, and reliability standards under Indian law. As per the BIS guidelines, it is mandatory for manufacturers of lead-acid storage batteries to obtain a license under the Compulsory Registration Scheme (CRS) or the ISI mark scheme, depending on the application and usage.

Manufacturers who do not comply with this requirement may face product bans, legal actions, and customer distrust. Hence, understanding the certification is vital for sustainable operations.

Standards Applicable to Lead-Acid Storage Batteries

BIS mandates that lead-acid storage batteries should comply with Indian Standard IS 13369. This standard specifies the requirements, methods of testing, and the labeling guidelines. Manufacturers need to conduct type testing, routine testing, and acceptance testing to meet BIS norms.

Key categories of batteries covered include:

• Automotive batteries

• Industrial stationary batteries

• Tubular lead-acid batteries

• Solar power batteries

The Certification Process Explained

The process to obtain BIS certification is detailed but achievable. Here's a simplified overview:

1. Application Filing: Submit the online application with required documents such as test reports, manufacturing details, and quality control plans.

2. Product Testing: Send samples to BIS-approved laboratories for testing as per the IS standard.

3. Inspection by BIS Officials: An inspection team may visit your facility to verify the infrastructure, quality control system, and manufacturing process.

4. Grant of License: If your product passes all parameters, BIS grants the certification and permits the use of the standard mark.

Importance of the ISI Mark for Lead-Acid Storage Batteries

The ISI mark is a symbol of quality and compliance in India. For lead-acid batteries, the ISI mark signifies that the battery is reliable, safe, and conforms to Indian standards. Consumers often look for ISI-marked products as a guarantee of quality.

The ISI mark also helps in:

• Enhancing product credibility

• Improving customer satisfaction

• Meeting government tender requirements

• Expanding domestic and international market reach

Testing Requirements and Quality Assurance

To qualify for BIS certification, lead-acid storage batteries undergo multiple stages of testing. Some key tests include:

• Capacity test

• Charge retention test

• Endurance in cycle test

• Resistance to overcharge and discharge

• Mechanical and dimensional check

Along with these tests, manufacturers must maintain detailed quality control records, standard operating procedures, and traceability mechanisms.

Role of a BIS Consultant for Lead-Acid Storage Batteries

Hiring a BIS consultant for Lead-Acid Storage Batteries can greatly simplify the certification process. Consultants bring in-depth expertise and ensure you avoid costly delays and compliance mistakes.

Their services often include:

• Document preparation and review
