My fresh charged batteries last around 3 hours. I want the 18560 battery which lasts most of the day on one charge. The vapor and throat hit is not as good with the 18650 battery. I think it is ok and to vape all day is great. To vape with GG with the 6v batteries,you need several batteries and another charger. I always have some on charge. This works out for me.
I need the 18650 battery to be able to go away for the day. Sometimes you cannot charge. Go away for the day and GG cannot go with me.
I have charged up alot of batteries and took them with me. There is a problem with that too. They will not last long,because they lose there charge.
