Bkrownd, I buy Duracell NiMH 1800 mah AA as well as AAA from mcminone.com and from different eBay sources for a little over $1 each.

VR, thanks, I had seen those but was holding out for something with a threaded seal. I may go ahead and get a set for my next battery box.

Does anyone know a source of round power cord similar to the kind that usually comes on bike lights? Something 4-5 mm diameter?
