Hi all. avid vap-head, first time poster, hence the noob page. having an issue with my vision 1500 mAh. I bought the battery as my first base, and have since upgraded to a MOD, but still use it as a back up. today, it was working like a champ after i killed my mod battery. on the way home, the battery started dying, so i gave it a rest. got home, threw it on the charger, and nothing. charger plug still showing green solid and not changing status. LED still lights up and stays active, but won't activate the atomizer. I've never taken one of these apart before, and im probably just past my warranty. suggestions?
