Hello , we did a real-time video link . I had two chargers and two batteries so was able to illustrate and deduce issue as battery specific. . I'll have to reiterate that Brea at Rad was super patient as I had to dig into my phones settings to make link work . Also , after doing a deep dive on this site I saw Mike B 's info on battery fuse replacement. I performed this last night , and it worked . " Bad" Battery charged fully. So now I have an extra battery ! Happy it didn't end up in the landfill . Hard to believe there's replaceable fuse that isn't easily accessible on these things.
