Disposing of disused lithium batteries from Lenovo computers
A button-shaped lithium battery is installed inside your Lenovo computer to provide power to the computer
clock while the computer is off or disconnected from the main power source. If you need to replace it with a
new one, contact your place of purchase or contact Lenovo for service. If you need to dispose of a disused
lithium battery, insulate it with vinyl tape, contact your place of purchase or an industrial-waste-disposal
operator, and follow their instructions.
Disposal of a lithium battery must comply with local ordinances and regulations.

Battery recycling information for the European Union
Notice: This mark applies only to countries within the European Union (EU).
Batteries or packaging for batteries are labeled in accordance with European Directive 2006/66/EC
concerning batteries and accumulators and waste batteries and accumulators. The Directive determines the
framework for the return and recycling of used batteries and accumulators as applicable throughout the
European Union. This label is applied to various batteries to indicate that the battery is not to be thrown
away, but rather reclaimed upon end of life per this Directive.
In accordance with the European Directive 2006/66/EC, batteries and accumulators are labeled to indicate
that they are to be collected separately and recycled at end of life. The label on the battery may also include
a chemical symbol for the metal concerned in the battery (Pb for lead, Hg for mercury, and Cd for cadmium).
Users of batteries and accumulators must not dispose of batteries and accumulators as unsorted municipal
waste, but use the collection framework available to customers for the return, recycling, and treatment of
batteries and accumulators. Customer participation is important to minimize any potential effects of batteries
and accumulators on the environment and human health due to the potential presence of hazardous
substances.
Before placing electrical and electronic equipment (EEE) in the waste collection stream or in waste collection
facilities, the end user of equipment containing batteries and/or accumulators must remove those batteries
and accumulators for separate collection.
