bis-crs-mark-registration-lead-acid-battery-is-16270-2014Lead-acid batteries have been around for a long time and they still power many things we use every day. Cars, UPS systems, solar power units and even small industrial tools depend on them. Because these batteries store energy in chemical form the Government of India placed them under mandatory BIS CRS certification. The main standard here is IS 16270:2014, which sets rules for safety, construction and performance

This requirement came in to make sure the batteries entering the market do not create risks like leakage, overheating or short life cycles. Many buyers don’t check these things, so the responsibility basically shifts to manufacturers and importers.

Why Lead Acid Batteries Need BIS CRS Certification

Lead-acid batteries can fail in ways people don’t expect. A battery might overcharge, release harmful gases or lose capacity too fast. BIS certification acts like a safety barrier. It forces companies to follow a fixed standard before placing their products in the market.

Some reasons the certification matters:

  • prevents unsafe batteries from entering homes or vehicles
  • improves reliability during backup power situations
  • ensures proper labeling and traceability
  • reduces environmental and handling risks

IS 16270:2014 covers both performance and construction requirements, which means everything from the plates to the electrolyte and terminals must meet the right specifications.

Who Needs to Get the CRS Mark?

The rule applies broadly but a few groups deal with it more than others. Mainly:

  • manufacturers producing lead-acid batteries inside India
  • importers bringing batteries from other countries
  • brands who sell batteries under private label arrangements

Anyone placing the product in the Indian market must get certified. Even if a company buys batteries from a third-party factory abroad, they still must obtain their own CRS mark.

Products sold only for export are not covered. But once something touches the Indian market—retail, wholesale, or OEM—certification becomes mandatory.

What IS 16270:2014 Actually Covers

Some people think BIS standards are just paperwork but IS 16270:2014 is technical. It looks deeply at construction and electrical behavior of batteries

Key points include:

  • container and cover material: must handle heat and mechanical stress
  • electrode plates: thickness, purity, and grid design
  • electrolyte level and stability
  • capacity rating under specific discharge conditions
  • safety performance under short-circuit or high-temperature situations

It also checks shelf life performance and how the battery reacts during long-term storage. These things matter because poor-quality batteries can degrade even before the user installs them.

Process of Getting the CRS Mark for Lead Acid Batteries

The pathway is similar to other CRS-listed products, but batteries have extra testing steps. The process looks somewhat like this, though each manufacturer experiences it a little differently:

1. Application Filing

A company submits product details, technical documents, circuit diagrams (if applicable), and labeling samples. BIS uses these papers to identify whether the product falls exactly under IS 16270:2014.

2. Product Testing at BIS-Recognized Lab

This is the most time-consuming part. Labs test:

  • discharge cycles
  • charge retention
  • overcharge behavior
  • durability under vibration
  • terminal strength

3. Lead-acid batteries

Need multiple cycles for accurate measurement, so labs sometimes take longer than expected.

4. Review of Test Reports

After testing, the lab sends a report to the manufacturer and uploads it to BIS. Officers compare results with the requirements of the standard.

5. Grant of Registration

If everything checks out, BIS issues the CRS registration. The manufacturer can then print the CRS mark on their batteries, packaging, and promotional material.

CRS registration remains valid for two years. Renewal requires fresh documents but usually not full testing unless something has changed.

Benefits for Manufacturers and Buyers

Manufacturers sometimes feel the process is a hurdle, but it strengthens their product line in the long run. A certified battery usually offers:

  • better performance consistency
  • longer operational life
  • fewer warranty claims
  • stronger brand value

For buyers, whether they are car owners or businesses running UPS systems, a BIS-certified battery signals safety. Since lead and acid are hazardous materials, this assurance matters.

A properly certified product also means the manufacturer follows a structured quality control process. That reduces the risk of early leakage, swelling, or failure under load.

Common Mistakes Companies Make During Certification

A few recurring issues appear when companies try to get certified. Some of them include slightly incomplete documentation or unclear labeling. Even small missing details—like the wrong model code—can delay approval.

Another problem is sending samples that are not from regular production batches. BIS rejects these because they want real production quality, not lab-adjusted pieces. Manufacturers should keep records clean and follow a fixed testing schedule.

Timeline for Certification

The timeline depends on lab waiting periods. On average:

  • application filing: 2–3 days
  • sample testing: 15–30 days
  • BIS review: 1–2 weeks

This estimate changes based on testing load or holiday delays. Batteries requiring multiple charge-discharge cycles often take longer.

Companies planning to launch a new model should start early so they don’t miss market season.

Conclusion

Lead-acid batteries power several important parts of our daily life, so it makes sense that BIS placed them under CRS rules. IS 16270:2014 ensures that the battery performs safely and gives a stable backup when needed.

Whether a company is manufacturing locally or importing from overseas, CRS registration is unavoidable. It protects consumers and forces better quality control across the industry. In the long run, certified products win trust, and trust builds long-term business.
