How to dispose of batteries in California

If you live in California, you must dispose of batteries very carefully when they are no longer useful; in fact, CalRecycle (California’s Department of Resources, Recycling, and Recovery) labels them as hazardous waste.

Since all of them contain toxic and corrosive materials, if they are not discarded properly, they can end up polluting the Earth, groundwater, and other surfaces.
However, laws about this subject are different in every state.

So, in this article, we will focus on explaining the main regulations and different ways to dispose of batteries in California.

What type of batteries must be disposed of?

In California, all types of batteries must be disposed of. These are part of the group of hazardous waste, and at the same time, they are categorized as universal waste.

This includes:

  • Alkaline batteries (AAA, AA, C, D, 6V, 9V).
  • Button cell.
  • Carbon Zinc (AAA, AA, C, D, 6V, 9V).
  • Lithium / Lithium Ion (3V, 6V, 3V button).
  • Ni-Cd and Ni-Li batteries (AAA, AA, C, D, 6V, 9V).
  • Lead-acid vehicle batteries (12V, 6V).
  • Silver Oxide.

Also, it does not matter if is rechargeable or for a single-use; none of them cannot be thrown away in the garbage, as you will normally do with other objects.

The proper thing to do is to discard them on an authorized waste disposal facility or recycling center.

Where to recycle them?

As we mentioned before, the proper way to dispose of batteries is to find a local recycling center to avoid any type of pollution.

Fortunately, there are lots of facilities around California! You just need to find the nearest from you and get in touch with them to give your batteries away.

For your convenience, here are 3 ways to locate one:

What happens to the batteries?

If a battery is severely damaged, most facilities will get rid of it through special procedures. But, if there is something to save, it will be recycled.

  • Use gloves when manipulating batteries (especially if they are corroded or damaged). Then, put them in a fabric bag or a box (do not use plastic!), and make sure to wash your hands when you finish.
  • Try to buy rechargeable batteries (with their charger). This way, you will reduce the consumption of ordinary batteries.
  • Currently, there are lots of devices that do not use batteries. Instead, they are charged with through mechanical means (by winding, shaking, squeezing) or through sunlight.

Are batteries dangerous?

Most batteries contain Zinc, Mercury, Silver, Lead, and Cadmium. If they are thrown away into landfills, they will pollute soil, water, and other natural resources.

And, if a person gets to ingest or inhale these chemicals, they can cause severe damage to the body. Depending on the duration of the exposure, it can cause issues in the central nervous system, digestive system, and lungs.
