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.
Give alkaline batteries that still have some power left to a friend who might need them. If you throw out or get rid of the item that the batteries were in and have nothing else to use them with, then you can give them to a friend to reuse them and make sure the battery power does not go to waste.
Find local recycling companies in your area that might accept alkaline batteries for recycling. You can call your government office or use online resources, like the website Earth 911.com. Type "Single-use batteries" into the search box along with your zip code.
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.
Call local electronics stores if you don't live near any recycling centers that accept alkaline batteries. Electronics stores sometimes have recycling programs in place for items such as alkaline batteries.
