While you should recycle lithium batteries at Home Depot or somewhere similar, you can toss some alkaline batteries in the trash. Learn how to dispose of old batteries for iPhones, PCs, and other electronics properly.
Discard Single-Use and Non-Rechargeable Batteries
The most common battery type is the single-use and non-rechargeable alkaline battery, which comes in AA, AAA, C, D, 9-volt, and button cell (watch) sizes. If you have alkaline batteries made after 1997, you may be able to dispose of those batteries with your other garbage as these don't pose a toxic landfill danger under EPA standards. However, battery disposal requirements vary by state. New Jersey and Georgia are examples of states that allow alkaline batteries in the regular trash. In California, everyone must recycle all batteries.
Recycle Rechargeable Batteries
Rechargeable batteries used in camcorders, smartphones, laptops, and other devices present additional toxicity issues if disposed of in the trash. As a result, rechargeable batteries must be recycled and not discarded with other garbage.
Common types of rechargeable batteries include:Lithium-Ion (LiOn)Nickel-cadmium (Ni-Cad) Nickel metal hydride (NiMH)Nickel zinc (NiZn)
Before recycling, make sure you can no longer recharge the battery. If you wish to recycle a rechargeable battery that still accepts a partial charge, make sure you've run it down before recycling. If you don't need the battery charger anymore, you should also recycle it.How to Dispose of a Laptop Battery
Lithium-ion rechargeable batteries should never be placed in the trash or curbside recycling bins. These batteries could pose a fire danger.
How to Prepare Batteries for Disposal or Recycling
Before discarding your batteries, cover the battery contacts (especially the positive side) with non-conductive masking or electrical tape. Alternatively, put each battery into a small plastic bag so that they don't touch other batteries. Doing this is especially important for units that may be leaking.
Use electrical tape since cellophane (or pressure-sensitive) tape is prone to static electricity and doesn't always stick well. If you have several batteries, tape the contacts, then put the batteries in a non-conductive plastic or cardboard container for safe transport to a local electronics recycling center.
Where to Recycle or Dispose of Batteries
Check online for options in your location for disposing or recycling batteries. Enter keyword phrases into a web browser search engine, such as: "Recycle batteries near me" or "Recycle batteries (your city or county name)."

Select cities or counties may also allow you to put old household non-car batteries into a plastic bag or container and place it separately on top of (or next to) the other weekly garbage or recycling container for pickup. There are national battery disposal and recycling options that may provide local drop-off points as well.
