The crossed-out wheeled bin symbol on batteries or
accumulators means that they must not be disposed of
with household waste at the end of their useful life. If
batteries or accumulators contain mercury (Hg), cadmium
(Cd) or lead (Pb), you will find the respective chemical
symbol below the symbol of the crossed-out garbage can.
You are legally obliged to return old batteries and
accumulators after use. You can do this free of charge at a
retail store or at another collection point near you.
Addresses of suitable collection points can be obtained
from your city or local government.
Batteries may contain substances that are harmful to the
environment and human health. Particular caution is
required due to the special risks involved in handling
lithium-containing batteries. The separate collection and
recycling of old batteries and accumulators is intended to
avoid negative effects on the environment and human
health.
Please avoid generating waste from old batteries as much
as possible, e.g. by giving preference to batteries with a
longer lifespan or rechargeable batteries. Please avoid
littering public spaces by not leaving batteries or
battery-containing electrical and electronic devices lying
around. Please explore ways to recycle a battery instead of
disposing of it, such as reconditioning or repairing the
battery.
