After having battery issues with my previous runner 2, it was replaced by tom tom with a new one 2 months ago. Now i'm having trouble again when charging the battery. The battery shows as fully loaded after approx 30 min, but the battery sign is not completely full. Today after a plug in of more then 4 hours, I wanted to do a run, but after 30 min my watch was dead. Does anyone know if I can do something to resolve this issue or was this just a bad replacemen?. Thanks for your feedback.
