As someone who has vaped for awhile I think you are wasting time and money on all of the brands you listed. I think your best option will be to get some empty cartos and fill your own. You also should look into more standard batteries. 808 are what they recommend for stick style (ones that look like an analog). 808 is the thread style and these are sold under too many names to list. One of your current batteries may actually be an 808 but I don't know. As far as how far does juice go it's up to the person. A standard carto will hold around 1ml and that will last however long depending on how you vape. Good luck just don't get overwhelmed. There is a lot to learn but just take baby steps.
