ANATEL published Ato No. 10229/2026 amending Article 3 of Ato No. 5314/2026. The amendment postpones the mandatory application of the Technical Requirements and Test Procedures for Conformity Assessment of Secondary Lithium Accumulators for Stationary Applications from October 12, 2026 to October 12, 2027. Ato No. 5314/2026 had approved the technical and testing requirements and added the product type "Secondary Lithium Accumulator for Stationary Applications" to ANATEL's Reference List of Telecommunications Products. The new Act does not revoke or substantively change those technical requirements; it provides an additional one-year transition before mandatory application.

Impact

Impact assessment: Medium. This is a binding deadline change that materially affects certification planning for stationary secondary lithium batteries but does not change the underlying technical or test requirements.

Who is affected?

Manufacturers, importers, ANATEL certification holders, Designated Certification Bodies (OCDs) and laboratories handling stationary lithium accumulator projects.

Conclusion:

projects should update compliance timelines to October 12, 2027 while continuing to prepare against Ato No. 5314/2026.
