Approximately how long would you be able to charge and reuse a 3100mAh 18650 battery before you would have the need to buy new batteries. I am wondering because I've been using two for around six months now and my third battery I just bought back in November. I just feel like my vape isn't a awesome as it once was. May be a mental thing. May need a fresh atomizer or just a good cleaning but this post is just about the batteries and not about the atomizers. Any interesting or educational battery information would be most appreciated. (It is firing perfectly. I am still getting vapor and flavor. The batteries are all freshly charged. Still reading 4.2 straight off of my multimeter.) Also I hope that I put this in the correct forum area. Please let me know if I have placed this post in the wrong area.
