Local rules and collection options vary, so check your state or local waste authority before you dispose of a battery.
First, identify the battery chemistry
Do not choose a disposal route based on a battery’s size or shape. Lithium batteries can look like familiar alkaline cells, so read the label on the battery, the product markings, or the device manual. Look for the word “lithium” and, for a rechargeable battery, “lithium-ion” or “Li-ion.” If the chemistry is unclear, ask your local waste program or the product manufacturer rather than assuming the battery is alkaline.

That label check is the first decision in the disposal process because appearance is not a reliable guide. A battery that fits an everyday household device may still have a chemistry that needs a different collection route. If the cell is removable, inspect its casing. If it is installed in a device, check the manual or product markings. Do not infer that a battery is alkaline simply because it is a familiar size, has a recycling symbol, or came out of a common household product.

Can you throw alkaline batteries in the trash?
In most U.S. communities, used single-use alkaline and zinc-carbon batteries can go in household trash. The U.S. Environmental Protection Agency (EPA) nevertheless recommends recycling them when a suitable option is available or checking with your local or state solid-waste authority. State and municipal rules can be stricter than the general guidance, so confirm the rule where you live.
In practice, this means there is no single nationwide answer that overrides local instructions. If your local authority says these batteries may go in the trash, that is consistent with the general guidance for most communities. If it offers a battery collection option or directs residents to recycle them, follow that local route. Where the rule is unclear, contact the solid-waste authority rather than guessing. Collection options and requirements can differ by state and municipality.
Do not apply this advice to a cell merely because it has the same shape as an alkaline battery. A lithium single-use battery is not an alkaline battery, and rechargeable batteries need to be identified by their chemistry and handled according to the relevant collection program’s instructions. Checking the label before disposal helps prevent a lithium battery from being put in the trash under the mistaken assumption that all similar-looking household cells are alike.
Where do you dispose of lithium-ion batteries?
Take household lithium-ion batteries to a separate battery collection site or a household hazardous-waste facility. Some electronics retailers host collection points, but acceptance varies: check that the particular location accepts your battery type before making the trip. Your local or state waste authority, household hazardous-waste program, or the collection program’s current location finder can help you find an appropriate option.
When checking a potential drop-off location, confirm both that it accepts the chemistry you have and whether it accepts a loose battery or a device containing a battery. Not every collection point handles every type of battery or electronic product. If you are bringing a device with an installed battery, ask specifically about devices with built-in lithium-ion batteries. If the battery is damaged or swollen, say so when asking for instructions; routine drop-off rules may not apply.
The EPA says: “Lithium-ion (Li-ion) batteries and devices containing these batteries should not go in household garbage or recycling bins.” That includes curbside recycling bins. A recycling symbol on a battery or device does not mean it belongs in your curbside recycling cart. A recycling logo is not a substitute for checking which collection stream is intended for that product.

The reason is a fire hazard in the waste stream. Batteries can be crushed or damaged during collection or processing. A lithium-ion battery that is damaged in that way can create a fire risk, which is why it needs a separate route rather than ordinary trash or mixed curbside recycling. Keeping these batteries out of both bins matters: placing one in a recycling cart does not make it safer or ensure that it will reach a battery recycler.

If you cannot locate an accepted drop-off point immediately, do not use the trash or curbside recycling bin as a fallback. Check with the local or state solid-waste authority, a household hazardous-waste program, or the collection program for current options and instructions. A site’s location finder can be useful, but confirm that the specific site accepts your battery before you go.
How to prepare an undamaged lithium-ion battery for drop-off
For a removable, undamaged lithium-ion battery, prevent its terminals from touching conductive material or another battery while it is being transported. The EPA recommends covering the terminals with non-conductive tape; it prefers electrical tape. Other non-metallic adhesive tape can work. Alternatively, place each battery in its own plastic bag. Follow any additional preparation instructions from the collection site.
Terminal isolation is a straightforward precaution, not permission to ignore a receiving program’s rules. A collection point may have its own preparation directions, so check those first. If it specifies a method, follow it. If the battery is undamaged and no different instructions apply, use non-conductive tape over the terminals or put that one battery in its own plastic bag. Do not put multiple batteries together in one bag as a substitute for individually isolating them.
- Confirm acceptance. Contact the collection site or check its current instructions to make sure it takes that battery type and to learn how it wants batteries prepared. Ask whether the location accepts loose batteries or only certain items.
- Keep the battery intact. Do not bend, crush, puncture, or otherwise damage it. Keep its label legible where possible, since the label can help identify what it is.
- Isolate the terminals. Cover them with non-conductive tape, preferably electrical tape, or put the battery in its own plastic bag. Do not tape over the label if it can be avoided.
- Take it to the designated collection point. Do not put it in household trash or a curbside recycling bin while waiting for drop-off. Follow the collection program’s directions for delivery.
These routine steps are for batteries that are not damaged or swollen. If a battery appears damaged, do not assume that taping it or bagging it makes it safe for an ordinary collection point; get handling instructions first. Protecting terminals is a precaution for a normal drop-off, not a way to make an unsafe or damaged battery suitable for routine collection.
What if the battery is built into a device?
Some lithium-ion batteries are difficult to remove. If a battery is built into a phone, computer, or another device and does not come out easily, do not pry it out. Breaking, bending, or crushing the device can damage the battery and create a fire hazard.

Do not try to force access to a battery just to separate it from the device. EPA notes that some batteries are difficult to remove and can pose a fire hazard if broken, bent, or crushed. A device that appears to have a removable cover may still require product-specific instructions; if the battery does not come out easily, stop rather than applying force.
Take the device to an appropriate electronics recycler or household hazardous-waste program, and follow that program’s instructions for devices with built-in batteries. Confirm that the specific facility accepts the device before bringing it in. The battery and the device may be handled through a different collection route than a loose battery, so check in advance instead of placing the whole device in household trash or curbside recycling.
What to do with a swollen, damaged, or recalled battery
A swollen lithium-ion battery is damaged and may present a fire hazard. Do not treat it as an ordinary battery drop-off or rely on the routine terminal-taping steps. When there is no imminent threat, contact the product manufacturer, retailer, state waste agency, or local household hazardous-waste program for specific handling directions. While waiting, keep the battery in a safe place away from flammable materials.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteBe clear when asking for help that the battery is swollen or damaged. The right next step depends on the handling instructions from the manufacturer or local program, so a standard location finder or ordinary battery collection point may not be enough to answer the question. Keep it away from flammable materials while you await direction, and do not bend, crush, puncture, or pry at it.
If there appears to be an imminent fire risk, emergency services may be needed. For a recalled battery, follow the manufacturer’s or recall program’s handling instructions and contact the relevant program if you are unsure where it should go; do not assume that a standard collection site accepts it. Recall instructions can be specific to the product, so use the manufacturer or recall program’s directions rather than treating it as an ordinary undamaged battery.
Quick comparison by chemistry and condition
| Battery or item | General household route in the U.S. | Preparation or caution |
|---|---|---|
| Single-use alkaline or zinc-carbon battery | Household trash is allowed in most communities; EPA recommends recycling or checking local guidance. | State or local rules may differ. Confirm the chemistry from the label rather than the size. |
| Undamaged lithium-ion battery | Separate battery collection or household hazardous-waste facility; not household trash or curbside recycling. | Isolate terminals with non-conductive tape, preferably electrical tape, or bag each battery separately. Follow the receiving program’s instructions. |
| Device with a built-in lithium-ion battery | Appropriate electronics recycler or household hazardous-waste program. | Do not pry out a battery that does not come out easily, or bend, crush, or puncture the device. |
| Swollen or damaged lithium-ion battery | Get specific handling directions from the manufacturer, retailer, state waste agency, or local household hazardous-waste program. | Keep it away from flammable materials while awaiting direction. Seek emergency help if there appears to be an imminent fire risk. |
Use the table as a starting point, not a replacement for local instructions. The first distinction is chemistry: most communities allow single-use alkaline and zinc-carbon cells in household trash, while lithium-ion batteries and devices containing them need a separate collection route. The second distinction is condition: swollen or damaged lithium-ion batteries need specific direction rather than ordinary preparation and drop-off.

Common disposal mistakes to avoid
- Putting a lithium-ion battery in household trash: use separate battery collection or a household hazardous-waste program instead.
- Putting a battery or device in curbside recycling because it has a recycling symbol: lithium-ion batteries and devices containing them do not belong in municipal recycling bins.
- Assuming familiar size means alkaline chemistry: check the battery or product markings.
- Dropping off an unprepared removable battery: isolate its terminals or bag it individually, and follow the site’s instructions.
- Trying to remove a difficult built-in battery: take the device to an appropriate recycler or hazardous-waste program without prying the battery out.
- Treating a swollen battery like an ordinary used battery: get specific handling direction before choosing a collection route.
Two errors often start with the same assumption: that household batteries can all be handled alike. They cannot. First identify the chemistry, then consider whether it is loose or inside a device, and finally check whether it is undamaged. Those checks determine whether general alkaline guidance applies, whether a lithium-ion collection point is needed, and whether the battery requires special handling advice.
Keep button and coin cells away from children
Button and coin cells can be swallowed. Keep them away from young children while you identify the chemistry and arrange the correct disposal route. Do not leave a loose cell where a child can reach it during the time you are checking local instructions or preparing a drop-off.

Can I throw alkaline batteries in the trash?
In most U.S. communities, single-use alkaline and zinc-carbon batteries can go in household trash. EPA recommends recycling them when possible or checking with your local or state solid-waste authority. Follow stricter state or local rules if they apply, and do not use this guidance for a lithium or rechargeable battery just because it has a similar shape.
Where do I dispose of lithium-ion batteries?
Use a separate battery collection site or household hazardous-waste facility. Some electronics retailers host collection points, but confirm that the specific location accepts your battery type. Your local or state waste authority, local hazardous-waste program, or the collection program’s current location finder can help identify an option.
Can batteries go in curbside recycling?
Lithium-ion batteries and devices containing them should not go in curbside recycling or household garbage. They need separate collection because they can be damaged or crushed during collection or processing, creating a fire hazard. A recycling symbol does not mean a lithium-ion battery belongs in the curbside bin. For alkaline and zinc-carbon batteries, check local guidance; household trash is allowed in most communities, and EPA recommends recycling or checking with local authorities.
Do I need to tape battery terminals before recycling?
For an undamaged removable lithium-ion battery, EPA recommends covering the terminals with non-conductive tape, with electrical tape preferred. Other non-metallic adhesive tape can work. Putting each battery in its own plastic bag is an alternative. Follow the receiving program’s instructions, and do not treat this routine preparation as sufficient for a swollen or damaged battery.
