Okay so I bought my ego twist battery a little less than 2 months ago. When I plug the battery into the charger the light stays green. I know that it is not my charger, because I tested 2 other ones with no success. I know it is not a problem with the connection plate because I completely cleaned it out with a cu-tip and gently moved the plate up. In addition to this The battery still makes a solid connection with my ViVi Nova, all my regular boge cartos and even the dual coil smok tech's. When I connect them the battery flashes a bunch of times to signal me to charge it, but the battery won't connect to any chargers >.<
Edit: It has been fully functioning and charging fine up until this point
