Governing Protocols
We conduct testing strictly adhering to the latest regulatory frameworks, ensuring your product is globally and locally compliant:
- Indian Standard: IS 16048 (Part 1) : 2021
- International Equivalent: IEC 61951-1 : 2017
Battery Testing Standards IS 16048-1/IEC 61951-1 : 2021
In the competitive landscape of portable power, compliance goes beyond mere safety; it requires proven reliability. IS 16048-1 serves as the definitive benchmark for validating the performance and longevity of sealed Nickel-Cadmium (Ni-Cd) cells. Unlike basic safety standards, this protocol rigorously stress-tests the battery’s operational efficiency to ensure it meets the demands of modern electronics.
- Performance Validation: Confirms rated capacity and discharge efficiency.
- Lifecycle Assurance: Verifies endurance through rigorous cycle testing.
- Quality Control: Ensures dimensional accuracy and charge retention.
- Market Trust: distinguishing high-quality cells from generic alternatives.

Eligible Form Factors
This standard is specifically designed for Portable Sealed Rechargeable Single Cells using Nickel-Cadmium chemistry. We cover all major configurations:
- Small Prismatic Cells (rectangular formats)
- Cylindrical Cells (standard AA, AAA, C, D sizes, etc.)
- Button Cells (coin-type formats for compact electronics)
Rigorous Performance Metrics
Our testing regime goes deep into the electromechanical properties of the cell to simulate real-world usage scenarios:
- Dimensional Analysis: Precision measurement of height, diameter, and shape.
- Discharge Performance: Capacity verification at 20°C and low-temperature (-18°C) limits.
- Charge Retention: Evaluation of self-discharge rates during storage.
- Endurance (Cycle Life): Long-term testing to determine the total usable lifespan.
- Internal Resistance: AC and DC impedance measurement.
- Overcharge Acceptance: Stress testing the cell's ability to handle excess current.
Authorized Lab Accreditation
All testing is conducted in laboratories that hold top-tier credentials to ensure your reports are universally accepted:
- NABL Accredited: Conforming to ISO/IEC 17025:2017 general requirements for the competence of testing and calibration laboratories.
- BIS Recognized: Fully authorized for Indian regulatory submissions.
Project Completion Horizon
Due to the extensive nature of "Cycle Life" and "Endurance" testing, performance standards require a longer window than standard safety tests.
- Standard Turnaround: 4 to 6 weeks (dependent on the specific cycle-life class requested).
- Expedited Options: Available upon request for partial parameter testing.
Testing Sample Prerequisites
To ensure statistically significant results and accommodate destructive testing protocols, we require:
- Total Quantity: 25 – 30 Samples (Cells/Batteries) per model.
- Condition: Fresh samples (manufactured within the last 3 months) are recommended for accurate performance data.
Investment Structure
Pricing is calculated based on the specific cell capacity and the extent of endurance testing required.
- Custom Quote: Please contact our sales engineers with your technical datasheet for a precise estimation. We ensure zero hidden costs.
Technical Documentation Checklist
To initiate the project seamlessly, please ensure the following documents are prepared:
- Technical Data Sheet (TDS): Detailed specs including rated capacity (Ah), voltage, and dimensions.
- ISO 9001 Certificate: Manufacturer’s Quality Management System certificate.
- UN 38.3 Report: (If available) for transport safety reference.
- Marking Label: Copy of the artwork showing the brand, model, and polarity.
Frequently Asked Questions
No, IS 16048-1 is a performance standard. The mandatory standard for BIS CRS registration is IS 16046 (Part 1), which focuses strictly on safety parameters like fire and explosion risks.
IS 16046 verifies safety to prevent accidents, while IS 16048 validates performance metrics like capacity, cycle life, and discharge efficiency to ensure the battery lasts as advertised.
No, separate testing reports are required. Even if the chemistry is identical, different form factors and capacities require individual testing to verify their unique dimensional and electrical characteristics accurately.
Performance testing includes "Cycle Life" and "Endurance" tests, which physically charge and discharge the battery hundreds of times. This process is time-bound by the battery's chemistry and cannot be rushed.
We strongly recommend fresh samples manufactured within three months. Older cells often suffer from chemical degradation during storage, which can lead to false failures in capacity and charge retention tests.
While the IEC report proves international compliance, it cannot replace the IS 16048 test report for domestic tenders or specific Indian quality requirements unless explicitly allowed by the buyer.
If samples fail, the report is listed as non-compliant. You must improve the cell chemistry or internal design and resubmit fresh samples for a complete re-testing cycle.
