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.

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

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)

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.

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.

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.

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.

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.

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.
