A portable battery and accumulator is any source of electric energy generated by the transformation of chemical energy and composed of one or more cells where refilling is not possible (primary cells, also called batteries) or one or more cells where refilling is possible (secondary cells, also called accumulators).
They are divided into two groups:
- Primary batteries, intended for one-time use (e.g. zinc carbon and alkaline, button cells and lithium oxide batteries etc.),
- Secondary batteries, intended for refilling several times (e.g. nickel-cadmium, nickel-metal hydride, lithium ion and lead batteries with acid).
The management of waste portable batteries and accumulators (WPBA) is regulated by the Decree on the management of batteries and accumulators and waste batteries and accumulators (Official Gazette of Republic of Slovenia, no.: 3/10, 64/12, 93/12, 103/15), the 2016 goal of which is:
- To collect a minimum of 45% of average mass of PBA put annually on the Slovenian market in the last three years.
