(DIRECTIVE 2006/66/EC OF THE EUROPEAN PARLIAMENT AND THE COUNCIL

level of recycling waste batteries, discard waste batteries 

separately and properly through an accessible collection point in your vicinity. For 
more information about collection and recycling of waste batteries, please contact 
your local municipality, your waste disposal service or the point of sale where you 
purchased the items.
