Well, one of my friend told me that we are not supposed to throw used batteries in trash can. I am talking about the regular used aa batteries. Since then I am keeping them in the junk drawer but now my drawer is getting full. What am I supposed to do? Do recycling centers take these used batteries? Or could someone help me with the procedure of disposing of used batteries properly? I would really appreciate your replies. So please get back as soon as possible. Thanks.
