My first vivoactive HR required a new face. I purchased a new identical Vivoactive HR in the meantime and when my old one was returned repaired I used both in my training. After a few days I charged the old vivoactive HR using the charge cord that came with my new vivoactive HR. It burned out my older repaired (with a new face) vivoactive HR. The watch was extremely hot after a few hours on the charger. Why did this happen? What should I do? It was repaired by a certified garmin repair company. Now I’m back to only one watch :(( I need both. Thank you. Ann
