Have not contacted customer support. What link do you suggest? I would like to find a battery replacement closer to home, and cheaper. The battery is easy to replace and I think that by now, some of the owners of 602s have had to replace their batteries and have found cheaper alternative battery sources. I cannot find the link but I did see quite a while ago, a battery model # for the 602 and someone had done a how to on opening the cover -- by the way, duct tape on the back sticks firmly enough to be able to use it to pull the cover down and off. I could not do it with my hands alone.
