If you have a drawer filled with sticky, grimy old batteries and you don't know what to do with them, it's officially time you learn about where to recycle old batteries. Likely, you keep your decaying batteries in one place because you have no idea what to do with them, and are scared to touch them because for some reason, they're covered in a mystery film that your instincts tell you is not safe to touch. If it was also your instinct that tossing something as vial as a melted old battery in your trash will only increase the amount of hideous things in landfills, good on you.
But before you head to the recycling station, you'll need to sort things out. If it's a battery that you popped out of your TV remote or flashlight, it's called a single-use home battery. If its a battery that you extracted from a cell phone, computer, or a cordless tool or accessory, it's a rechargeable battery. There is a right way and a wrong way to dispose of old batteries, and unfortunately, if you accidentally pick the wrong way, the planet has to pay for it. Getting rid of single-use home batteries is a different process than getting rid of a rechargeable battery, so here's how to deal with both, properly.
