Lead acid automative batteries
You can recycle automotive batteries at Snohomish County recycling / transfer stations or hazardous waste facility.
You can also take automotive batteries to most local auto parts stores for recycling. If you need a new car battery, take your old battery with you. Sometimes they will give you credit for the old battery, as the materials in them are sought after.
