Alkaline batteries are mostly any batteries you have in your home that are for single-use, meaning they cannot be recharged and used again. However, this does not mean that you can never reuse alkaline batteries after they have been removed from a battery-powered item. Once you’re sure the alkaline batteries are completely dead, you can then dispose of them properly by recycling; they should never be thrown in with your regular trash.
Put the alkaline batteries into a battery-powered item that requires less power than the previous item. For example, a cassette player might require more power than a simple remote control, meaning you can reuse the alkaline batteries in the second item.
Contact each recycler on the list to ask if they accept alkaline batteries. Many recyclers do. Start with the one closest to you and take the batteries in once you find an acceptable recycler.
