It has been a hard week for replacing stuff around the house. I don't like to replace anything because it seems wasteful and not so ECO. If I can find things at resale shops or garage sales I am content, but the rechargeable battery/charger kits I have found at local department stores don't seem to last? So I'm going out on a limb and trying these nickel zinc version from an unknown manufacturing company. I found them at www.greenbatteries.com wish me luck!
