No one knows for sure what the risks are .I just use mine to beat the addiction to nicotine and I suppose I will one day wonder why I am bothering vaping no nic.For now it makes a good pacifier.There is no way to know what is in the liquid and what the long term effects of inhaling the vapors of what ever it is is.I would think the companies that have to go through the exporting system would be a little better documented and regulated than the stuff from someons garage or basement.They all have the same basic ingrediants but some for sure have other things than others .I have noticed that some of the better tasting liquids seem to me to form a hard carbon like substance on the element that I don't get with other liquids.I guess the main thing is is that it has to be way better than smoking.As far as battery life you can get mega batteries,extra batteries a PCC ,a mod or passthrough after you decide to stick with it.
