This guide outlines the EU Batteries Regulation, which aims to ensure that batteries placed on the European market are sustainable and safe throughout their life cycle. The regulation, effective from 17 August 2023, replaces the Battery Directive 2006/66/EC and applies uniformly across all EU countries without the need for national law transposition. The document details the types of batteries covered, including electric vehicle batteries, light means of transport batteries, industrial batteries, starter lighting ignition batteries, stationary battery energy storage systems, and portable batteries. It also describes the life cycle stages addressed by the regulation, such as raw materials production, battery production, use, repurposing, and recycling. Key requirements include sustainability and safety measures, labelling, digital battery passports, CE marking conformity, and waste battery management. The guide emphasizes the importance of compliance for manufacturers, resellers, and distributors within the European market.
