Important! The Bebat contribution is a legally mandated environmental contribution that Belgian consumers pay when purchasing a battery or battery-powered device in Belgium. Installers and retailers are required to charge this contribution and transfer it to Bebat . We therefore ask our Belgian customers to select this contribution at the time of purchase; otherwise, this cost may be charged after purchase.

The contribution is not due for:

• Foreign customers, when the battery is not marketed on the Belgian market;

• Traders or companies that manage their recycling obligations independently.
