anybody have this issue with this? have had this battery for about 2 weeks. it charged full to green light this morning. Used it 3 times today at about 10 puffs each time. Then the battery flashes out. I go to charge it and the light on the charger turns green after 10 mins of charging it. I go to use the battery again and a few puff in and the battery flashes again. I think I have a bad battery. Any one else have this issue?
