Old batteries do not belong to domestic waste because they could cause
damages of health and environment. You can return used batteries free of charge
to your dealer and collection points. As end-user you are committed by law to
bring back needed batteries to distributors and other collecting points.
Consideration of duty according to the law of electrical devices

local waste collection point or recycling centre. This applies to all countries of
the European Union, and to other European countries with a separate waste
collection system.
