I figured this might be the most correct forum to ask this since I've gotten some good advise from sound guys here! What do you guys do with your "used up" batteries? I was reading on the Duracell website and they wrote that its ok to throw away alkaline batteries. At my church we go through a lot of the AA Procell batteries and it feels wasteful to me. I know its necessary I use them on my line 6 g30 transmitter and appreciate their use but can regular alkaline batteries be recharged at all?
