Expanding the state battery stewardship program to include electric vehicle batteries.

SB 5045 expands Washington’s existing battery stewardship program to include electric vehicle (EV) batteries, which were previously excluded from the recycling requirements. The bill amends key statutes to redefine "vehicle battery" to encompass EV batteries, requiring retailers selling new EV batteries to accept used ones for recycling at the point of sale - similar to current rules for lead-acid car batteries. This includes maintaining a mandatory core charge (minimum $5) for new purchases if used batteries aren’t returned. The change directly affects EV battery retailers and consumers purchasing new EV batteries, extending the state’s recycling framework to cover this growing battery type.
