Battery Testing Standards IS 16048-2 : 2021/IEC 61951-2

In the competitive energy market, validating the true capacity of your Nickel-Metal Hydride (Ni-MH) cells is critical for brand reputation. This standard acts as the definitive rulebook for the dimensions, performance, and reliability of portable sealed rechargeable single cells. It goes beyond simple safety checks to ensure your product actually delivers the power promised on the label, filtering out low-quality imports and securing consumer trust in your technology.

• Capacity Verification: Confirms the cell meets its rated Ah capacity.
• Endurance Testing: Validates long-term cycle life and shelf-life stability.
• Physical Precision: Ensures dimensional compatibility for end-user devices.

We conduct rigorous testing in strict accordance with IS 16048 (Part 2): 2021, which is the direct Indian Standard adoption of the international benchmark IEC 61951-2. This alignment ensures that your testing results are not only valid for BIS (Bureau of Indian Standards) compliance but are also recognized globally as adhering to International Electrotechnical Commission protocols.

Our testing facility is equipped to handle the full range of Portable Sealed Nickel-Metal Hydride (Ni-MH) rechargeable single cells. This includes:

• Cylindrical Cells: (e.g., AA, AAA sizes)
• Small Prismatic Cells: (Rectangular formats)
• Button Cells: (Coin types for compact electronics)

To achieve certification, the cells must undergo a battery of performance-critical assessments. Our scope covers the entire lifecycle of the battery:

• Discharge Performance: Verification of Rated Capacity ($C_5$ Ah) at various currents ($0.2 I_t A$ to $1.0 I_t A$).
• Charge Retention: Measuring capacity loss after 28 days of open-circuit storage.
• Cycle Life Endurance: Testing the cell’s ability to withstand repeated charge/discharge cycles.
• Internal Resistance: Evaluating internal impedance for efficiency.
• Overcharge Capability: Assessing stability under prolonged charging conditions.

All tests are conducted in our NABL-accredited laboratory, ensuring the highest level of technical competence. Furthermore, our lab is fully recognized by the Bureau of Indian Standards (BIS) under the Compulsory Registration Scheme (CRS). A test report from our facility is the primary document you will need to apply for your R-Number and standard mark.

Due to the nature of performance testing—specifically the "Cycle Life" and "Charge Retention" (28-day) tests—this standard requires a longer duration than typical safety tests.

• Standard Lead Time: Approximately 6 to 8 weeks for full completion.

Note: Expediting is generally not possible for this standard as chemical reactions and discharge cycles cannot be rushed without violating the test protocol.

To run all parallel test clauses (including destructive or long-duration tests) without interruption, we require a robust sample set.

• Required Quantity: 25 to 30 Samples per model.
• Condition: Samples must be fresh (manufactured within the last 3 months) and supplied at approximately 50% state of charge.

Pricing is determined based on the technical complexity of the battery series.

• Single Model: Standard testing fee applies.
• Series Models: If you have multiple capacities or sizes, we offer series grouping discounts where applicable by BIS guidelines.

Please contact our sales team with your technical datasheet for a precise quotation.

To initiate the project and ensure your final report is valid for BIS submission, the following documents are mandatory:

• Technical Datasheet: Clearly stating Rated Voltage, Rated Capacity ($C_5$), and Dimensions.
• ISO Certificate: ISO 9001 certificate of the manufacturing unit.
• UN 38.3 Report: (If available, for transport safety verification).
• Marking Label: A clear image or draft of the battery label showing the model name and IS standard number.
