(DIRECTIVE 2006/66/EC OF THE EUROPEAN PARLIAMENT AND THE COUNCIL 
OF EUROPEAN UNION) (FOR EUROPEAN CUSTOMERS ONLY)

Batteries bearing any of these symbols indicate that

By ensuring compliance and conformance to proper disposal of waste batteries, 
potential hazardous effects on human health is prevented and the negative impact of 
batteries and waste batteries on the environment is minimized, thus contributing to 
the protection, preservation and quality improvement of the environment.
