I have just recieved my M401 e cig today. first of all when i put the battery in the charger it went red for only two minutes then went to green. I'm not sure if the batteries came fully charged or not. Also my first battery worked very well but when i attached the second one and took a drag it did not seem to produce any vapor at all. I'm thinkin the battery is dead or something? Any input would be great. Thanks.
