You will have to wait a long time for that unless they lic out the patent, i am sure they renew the patent. On the DC012 there are little to no battery discharge when you leave the battery in an unplugged radio, i have three of them, a DC011, DC012, and DC013. I can go days without using the unplugged radio, and when the battery dies i just throw in another one or plug the radio.
Sorry- Maybe I misstated- My understanding is that the DC011 depletes a fully charged battery over the course of a few days while the radio is turned *off* and is unplugged. So, if I put a fresh battery in Friday, and put it in my truck, it will be dead on Monday when I want to listen. This is what I'm asking for people's experience with... can anybody validate that this is no longer a problem on the DC012? Thanks & great site!
