Ok ill try to explain this the best I can. Recently 2 of my Manual 510 batteries are acting strange. Whats happening is, as soon as I press the button I can get about 2-3 seconds, sometimes less of vaping. The LED fades out as if its simply being drained of power. I have put these on the charger to make sure they are fully charged and same result after about 5 minutes of use. The first 5 minutes they seem to work normally. Then like clockwork, you press the button, begin to vape and the light just fades out to nothing. I searched the site, cant find anything unless im doing the search wrong.
