Household Batteries

All batteries are considered hazardous waste in California when they are discarded. This includes batteries of all sizes from AAA, AA, C, D, button cell, 9 Volt, and more, both rechargeable and single-use. Battery recyclers melt down spent rechargeable and household batteries in a high-temperature process, then reclaim materials such as nickel, iron, lead, cobalt, and cadmium.

At Your Door Service Has Been Discontinued


If you live in Atherton Belmont, Burlingame, East Palo Alto, Foster City, Hillsborough, Menlo Park, Redwood City, San Carlos, San Mateo, or a variety of neighborhoods in the unincorporated areas of the County, you were previously eligible for the HHW Door-to-Door Pickup program, but as of January 1, 2017 that program has been discontinued.  The San Mateo County government did not administer this program but is helping to spread the word about the transition.

Household Hazardous Waste material can continue to be taken to the San Mateo County HHW collection facility or a temporary collection event.



Use the County’s Household Hazardous Waste (HHW) Program

Have you cleaned out your house recently and have a large load of HHW ready?   Make an appointment online and drop off your batteries along with everything else.



Reduce Your Battery Waste – Use Rechargeables!


You can save thousands of single-use batteries just by switching a few out for the rechargeable variety. Rechargeable batteries cost a little more to buy, but last so long they quickly save you money.

Learn more about buying and using rechargeables with this fact sheet (pdf).


Good news! In California, almost all stores that sell rechargeables must take them back, when you do finally wear them out. Visit Call2Recycle to learn more about store take-backs.
