Batteries are used in millions of devices every single day. No matter how or where you use them, all batteries use the same basic technology.
Types of batteries
- Alkaline – These are the batteries you use in common appliances every single day. They come in sizes like AA, AAA, C, D, and 9V. Alkaline batteries perform well at low temperatures and have become essential in everyday life. You might use them in the keyboard at your desk, your alarm clock, a hotel door lock, or your electric razor.
- Lithium – Lithium batteries typically have a longer life, so they are used in everything from laptops and cellphones to medical devices like pacemakers. Lithium batteries get their name because they use metallic lithium as the anode.
- NiCad – A nickel cadmium battery (or NiCad) holds the same voltage until almost the end of its life, making it very reliable. Another bonus: you can also recharge them. NiCad batteries are often found in cordless power tools, digital cameras, and two-way radios.
- Sealed Lead Acid – Your car battery is most likely a lead acid battery. Sealed lead acid batteries are safer because they have a coating to prevent leaking. You’ll find sealed lead acid batteries in emergency devices like wheelchairs, emergency exit signs, and security systems. They are also rechargeable.
Should I recycle batteries?
If your batteries for your TV remote just died, it’s fine to throw them away in every state except for California, where it’s now illegal to throw away any batteries.
Most of the common batteries found used in your household are no longer made of hazardous materials like mercury, cadmium, and lead. But other batteries that contain heavy metals should be recycled, like alkaline, nickel cadmium, zinc-carbon, rechargeable lithium-ion, nickel-metal hydride (NiMH), mercury, and silver-oxide.
Rechargeable batteries should be recycled.
