I foolishly left the batteries in my elliptical when I let it sit idle for years. Now I want to use it. The batteries were so badly corroded, that one of the wire coils inside the battery holder, that makes the "connection" between the battery and the electronic display was so rusted, that it fell right off. Therefore, I need to replace that battery holding box that's inside the battery compartment. Anybody know how I could get a replacement for this?
