Where to take computer batteries for disposal

Computer batteries — whether they are lithium-ion laptop batteries, CMOS batteries from motherboards, or backup power supplies — cannot go in your regular trash or recycling bin. They contain materials that can catch fire in garbage trucks or landfills, and metals that contaminate soil and water. Most communities have at least one free or low-cost drop-off location within a short drive.

Start with your local waste management authority's website or call their main line and ask where to drop off rechargeable batteries. Many cities run collection events twice a year. If your area does not have a dedicated event, check whether Best Buy, Staples, or Home Depot near you accepts batteries — most do, at no charge, though some limit the quantity per visit. Retailers that sell batteries are often required by state law to take them back.

If you have a large number of batteries or work in an office, contact a local electronics recycler directly. Search "electronics recycling near me" or "battery recycling [your city]" to find businesses that specialize in this. Some charge a small fee for bulk drop-offs, but many accept household quantities free.

Key Takeaways

  • Computer batteries must not go in household trash or curbside recycling because they can ignite in trucks and landfills.
  • Your city or county waste authority can tell you the nearest free drop-off location or collection event in one phone call.
  • Retailers like Best Buy, Staples, and Home Depot accept rechargeable batteries at no charge, though quantities per visit may be limited.
  • Mail-back programs exist for small quantities, but driving to a local drop-off is usually faster and costs nothing.
  • Before dropping off a laptop battery, remove it from the device and place it in a plastic bag to prevent accidental contact with metal objects.

Preparing batteries before drop-off

A battery that is still in your laptop or device should be removed first. Power off the device completely, then follow the manufacturer's instructions to access and remove the battery — this usually means removing a few screws or unlatching a panel. If you are not comfortable opening the device, many electronics repair shops will remove it for a small fee, or you can bring the whole device to a recycler and let them handle it.

Once the battery is out, place it in a plastic bag or wrap the terminals loosely with non-conductive tape (painter's tape or electrical tape works). This prevents the battery from touching metal objects or other batteries during transport, which could cause a short circuit. Do not seal the bag airtight — batteries need air circulation. If the battery is visibly swollen, cracked, or leaking, put it in a separate bag and tell the drop-off staff when you arrive.

Transport the battery in your car, not in a hot trunk or sealed container. If you are mailing a battery through a mail-back program, the program will provide a prepaid shipping box designed to meet safety standards — use only that box, never a regular cardboard box.

Mail-back programs for small quantities

If you have one or two batteries and no convenient drop-off nearby, mail-back services exist but are slower and less common than local options. Call2Recycle operates a mail-back program in the United States and Canada; you can enter your zip code on their website to see whether they accept your battery type and what the cost is. Some programs are free for small quantities, while others charge $5 to $15 per box.

Mail-back makes sense only if the nearest drop-off is more than 30 minutes away and you are willing to wait two to four weeks. The shipping box is designed to contain any leakage or fire risk, but it still requires careful packing and adds time. For most people, a local drop-off is faster and free.

What happens to batteries after drop-off

When you drop off a battery at a recycler or retailer, it goes to a specialized facility where it is sorted by chemistry type — lithium-ion, nickel-cadmium, lead-acid, and others are processed differently. The facility then disassembles the battery, separates the materials (cobalt, nickel, lithium, copper, plastic, and steel), and sells them to manufacturers who use them to make new batteries, stainless steel products, or other goods.

This process recovers 90 to 95 percent of the materials in most rechargeable batteries, which is why recycling is far better than landfilling. The metals are valuable, so recyclers have an economic reason to do the work properly. Your battery does not sit in a warehouse — it is processed within weeks.

Disposing of non-rechargeable batteries

Alkaline batteries (the AA, AAA, and 9-volt batteries in remote controls and flashlights) can often go in household trash in most U.S. states, because they no longer contain mercury and pose less fire risk than rechargeable batteries. However, some states and cities ban all batteries from trash. Check your local rules before throwing them away.

If you want to recycle alkaline batteries instead of trashing them, the same drop-off locations that take rechargeable batteries usually accept them. The process is the same: call your waste authority or visit a retailer's customer service desk and ask. Alkaline batteries are less valuable to recycle than lithium-ion ones, but recycling them still prevents metals from entering landfills.

Handling damaged or swollen batteries

A battery that is visibly swollen, cracked, leaking, or has a burnt smell is damaged and requires extra care. Do not attempt to use it or charge it. Place it in a plastic bag by itself, away from other batteries and metal objects, and store it in a cool, dry place until you can drop it off. Do not seal the bag — leave it open so gas can escape if the battery vents.

When you arrive at the drop-off location, tell the staff when ready that the battery is damaged. They have procedures for handling it safely and will not be surprised. Damaged batteries are common and recyclers expect them. Never mail a damaged battery unless the mail-back program specifically says it accepts damaged batteries and provides a special container.

Computer devices with built-in batteries

Some devices — tablets, e-readers, wireless mice, and some modern laptops — have batteries that are glued or soldered in and cannot be removed without destroying the device. For these, you have two options: take the whole device to an electronics recycler, or check whether the manufacturer has a take-back program.

Apple, Dell, HP, Lenovo, and most other major computer makers accept old devices for recycling, sometimes free and sometimes for a small fee. Visit the manufacturer's website and search for "recycling" or "trade-in" to find their program. If the device still works, some makers offer credit toward a new purchase. If you prefer not to contact the manufacturer, any local electronics recycler will accept the device and remove the battery safely.

Frequently Asked Questions

Can I throw a computer battery in the trash?

No. Lithium-ion and other rechargeable batteries can ignite in garbage trucks or landfills and are illegal to trash in most places. Alkaline batteries (AA, AAA, 9V) may be legal to trash in your area, but recycling is safer. Call your local waste authority to confirm what is allowed where you live.

What if I cannot find a drop-off location near me?

Call your city or county waste management office — they are required to know where batteries can be recycled and will give you the nearest option. If that does not work, search "battery recycling [your state]" online or visit Call2Recycle's website to find mail-back options. A drop-off location almost always exists within 30 minutes of any populated area.

Do I have to remove the battery from my laptop before recycling the whole device?

No. You can bring the laptop with the battery still inside to an electronics recycler, and they will remove it safely. However, if the battery is damaged or you are mailing the device, removing it first is safer. If you remove it yourself, place it in a plastic bag and drop it off separately.

How much does it cost to recycle a computer battery?

Most drop-off locations — waste authorities, retailers, and local recyclers — accept household quantities of batteries free. Mail-back programs may charge $5 to $15 per box. Bulk commercial recycling may have a fee, but for a few home computer batteries, expect to pay nothing.

Is it safe to store old batteries in my home while I wait to recycle them?

Yes, as long as they are undamaged and stored in a cool, dry place away from metal objects and flammable materials. Keep them in a plastic bag or container. Do not store damaged, swollen, or leaking batteries indoors — take those to a recycler right away or store them outside in a safe location.
