Previously, the prepaid recycling cost was only applicable to household batteries weighing up to 5kg. This cost was added to retail price. Other forms of battery had recycling costs calculated at their disposal.
Following research into the costs of recycling batteries types other than household, the Swiss Federal Department of Environment, Transport, Energy and Communications made the decision to expand the prepaid recycling cost initiative.
So as of 1st January 2012, there is no distinction between different weights and types of battery as all have prepaid recycling obligations placed upon them.
