Batteries power our daily lives, whether we realize it or not. They help us power through daily chores and activities, stay connected with one another, and they can even help shine a light on some dark situations. In fact—nearly every electronic device that we own has a battery that requires proper handling. And whether your batteries are single-use alkaline, rechargable, or lithium-ion—they all eventually reach the end of their life.
It’s time to take charge of your battery disposal and learn how you can help make a positive environmental impact with your actions.
WHY DOES PROPER BATTERY DISPOSAL MATTER?
Batteries that find their way into our black garbage carts end up in our local landfill. After a little time, they can corrode and allow harmful chemicals to leach into the soil and make their way into our water supply.
Batteries can also cause landfill fires which release toxic chemicals into the air, leading to potential health problems for anyone who inhales those fumes. Help make a positive impact on our environment by not disposing of used batteries in your garbage. Instead, explore the different battery disposal methods below.
DID YOU KNOW 3 billion batteries are thrown away and end up in landfills every year?
DID YOU KNOW chemicals in batteries can cause everything from serious skin irritation to cancer?
Batteries that end up in our blue recycling carts are brought to the Shoreway Environmental Center. In 2016 a battery started a 4-alarm fire that closed the facility for months and caused millions of dollars in damages.
In fact, lithium-ion batteries have caused concerns for many consumer products such as cell phones, laptops, and headphones that explode or catch on fire. Properly disposing of your batteries and taping your battery terminals can help keep your home and community safe.
Which types of batteries should I be on the look out for?

WHY ARE BATTERIES CONSIDERED HOUSEHOLD HAZARDOUS WASTE?
Used batteries can still hold a charge which classifies them as household hazardous waste.
Household hazardous waste are items that contain chemicals. If these products are handled or disposed of incorrectly they can contaminate our soil, drinking water, and air. They can also pose a threat to human health, animals, and the environment. In California, it is illegal to dispose of household hazardous waste in the garbage or recycling, down the drain, or by abandonment. This includes your household batteries listed above.
DID YOU KNOW 5.8 lithium-ion batteries are found improperly disposed of on the recycling sort line every hour?
We’ve received lots of battery related questions and wanted to share the answers with our RethinkWaste community. Click here to find the battery answers you’ve been looking for.
Which batteries are the most dangerous?
Lithium-ion batteries contain more power than other batteries and are delicately packaged. When damaged, the battery can short out, heat up, and catch on fire as seen in the video below. Click here to learn more about lithium batteries and the types of products they can be found in.
Why is taping battery terminals helpful?
Why do I have to use clear tape to tape my battery terminals?
Clear tape (like the small rolls you use at home or packaging tape) is essential for our team to properly sort the different battery types. Because there are quite a few different types of batteries that need to be sorted by chemistry make up, clear tape allows us to read the various labels and ensure the correct battery gets placed with its friends. Dark tape like electrical or duct tape would prevent us from reading the labels clearly.
Are rechargeable batteries better than single-use batteries?
Rechargeable batteries are reusable, resulting in reduced waste and cost. However, reusable batteries contain more chemicals than single-use alkaline batteries, so you must remember to handle them with care.
What types of bags can I put my batteries in?
You may place your batteries in any clear zip-top bag.
Why can’t I place my batteries with my other recyclables?
Batteries contain materials/metals that can be recycled, but not in the normal way your blue cart materials are recycled. Since batteries contain chemicals and potentially leftover charge, they must go through a separate process to safely extract the valuable materials inside.
What are the most common products that people mistakenly think don’t have batteries but actually do?
Some of the most common items that people forget have batteries are the smaller everyday things that have lights such as light-up or musical greeting cards, light-up shoes, and even light-up pens. We see those in the garbage a lot. If you’re not sure whether a product has a battery, a good rule of thumb is to remember that nearly every electronic device that has an on/off switch, makes sounds, or has lights, has a battery.
What do I do with my lead-acid batteries from cars or computers?
Lead-acid batteries are accepted at the Shoreway Public Recycling Center for proper disposal.
What do I do with products that have embedded batteries such as laptops, toothbrushes and/or razors?
It’s best if you can remove the battery safely from the device. If you cannot, e-waste items with batteries such as laptops, cell phones, and MP3 players can be taken to the Shoreway Public Recycling Center in San Carlos free of charge. Other items with embedded lithium-ion batteries such as toothbrushes, razors and vape pens should be properly disposed of via San Mateo County’s Household Hazardous Waste Program. You can make an appointment online at smchealth.org/hhw.
Where do batteries go and what happens to them?
Batteries that are properly collected get sent to a third-party that sorts the batteries by type and then they safely extract the valuable metals inside.
