I have a smoktech winder 1300 mah, I understand the battery is fairly large for an ego style battery and may take a while to charge but Ive literally never seen any indication that its fully charged. I have a no name charger, when I plug it up the battery flashes a few times and then stays on, the charger has a steady red light that blinks green every 5 or 6 seconds. I've had it for about 2 months, It's gone dead quite a few times and Ill charge it for like 6 hours and the lights dont change on the charger or battery. I don't want to screw my battery up but I don't know when its fully charged. I'm charging it in an outlet with a wall adapter. thanks.
