Sparks 3 Battery completely empty, not showing charging picture on screen
I went on holidays for two weeks without my sparks 3 and have come back wanting to go for a run. The battery is completely emptied (I assume, after two weeks) and when I connect it to a power source (plug point or computer) it shows the battery with a slash but it does not show that it is charging. Has anyone else experienced this? Do I just leave it plugged in and hope for the best?
