On February 10, 2026, the Bureau of Indian Standards (BIS) issued new guidelines mandating the measurement and verification of the rated capacity for portable sealed secondary lithium cells and batteries. This regulatory update aims to protect consumer interests by addressing instances of misdeclaration of rated capacity. The directive enforces compliance with the test method specified in clause 7.3.1 of IS 16047 (Part 3):2018/IEC 61960-3: 2017, focusing on discharge performance at 20 degrees Celsius.
Implementation for Existing Licensees
The guidelines outline specific timelines and requirements for existing licensees. Manufacturers with licenses valid up to April 30, 2027, must ensure compliance with the new rated capacity verification by that date. For licenses extending beyond April 30, 2027, compliance is required by the license’s expiration date.
Existing licensees are required to submit test reports from third-party laboratories for all lead models covered under their current scope. Furthermore, laboratories must report the measured capacity in a modified Unified Test Report Format. Licensees must also provide an undertaking that remaining models comply with the new testing standard. Failure to meet these deadlines may result in the suspension or cancellation of the license, or the deletion of specific models from the license scope.
Requirements for New Applicants and Scope Changes
For new applicants, applications currently in process where a sample has been submitted or a test report issued may proceed without the additional rated capacity test, provided an undertaking is submitted to provide the report by the license’s expiration date. However, starting May 1, 2027, no new licenses will be granted under IS 16046 (Part 2) unless the additional test for rated capacity is included in the test report. These provisions also apply to any requests for changes in the scope of an existing license.
