Disposal
For the disposal of batteries in the EU, the 2006/66/EC
directive of the European Parliament
applies. Due to the contained pollutants, batteries must not be disposed of as household waste.
They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use
them or give them to a recycling company which disposes of the devices in line with law.
For countries outside the EU, batteries and devices should be disposed of in accordance with
your local waste regulations.
If you have any questions, please contact PCE Instruments.
