I've been searching all the posts on this forum. The answer to my question is probably here somewhere, but so far I can't find it. The charger is pretty easy to read. It shows which way to put the batteries in to charge. So I inserted my used batteries from my first day vaping my new infinity, plugged the charger in and the lights turned green. This morning the lights were still green. Is this normal? I guess I was expecting red while charging and green when done. In case I did something wrong....I don't want to put them back in my infinity. 
BTW...I can't even pick up my existing e-cigs to vape on. I'm using the infinity exclusively. I don't think I can go back. I just love it so much!!!!
