This is something I've never done. I did a quick check and found a local company called Nu-Life Industries that I'm going to check out. I'll let you know what I find out - meanwhile I'm prepping for our trip on Sunday. No time for recycling batteries until we get back, but then I'm going to look into this more closely. Having two young kids we go through a lot of batteries, so this is an area where I can make a difference.
That's all for now!
