Purchased in August 2018 and not frequently used. My 735xt was working fine until a few weeks ago. Been in drawer due to injury. Came to try it today and appeared to be dead. I thought battery had run out. Tried to charge it for several hours but all that happens is the screen cycles through Garmin logo and an image of a battery with a small red bar on its left constantly cycle over and over again. Watch won't turn on of its own accord or via power button. Tried several other chargers since with same result. Also tried soft and hard reset with no response. I'm assuming the battery is faulty, but would welcome any advice before junking the watch
