I was vaping with my Volt Spinner 600 when the light on the battery started blinking which meant it was time to recharge. Before I plugged in the charger, the light on the battery stayed lit. I pressed the button 5 times but it's still lit. It's not blinking. I thought if I plugged it in the light would go off and it would charge but the light stays on and it's not charging. The light has been on for about 10 minutes now. Any idea's?
