In short, the amp varies from battery to battery, honestly, if you're having to ask this question about batteries and mech's, you may want to do a little more research into battery safety and ohm's law, especially if you plan on building your own coils, which I assume you are heading in that direction. You will also need an ohms meter at some point. There are plenty of threads here you can read and you've been given some good info here, but if you were like me and a lot of us, it may not mean much at this point, but then again you may be smarter than I!
You can also check out some good videos, there's an older gentleman who does and excellent, to the point video on starting out with mech's and battery and basic safety and you can check out Pbsardo's website, which I found the best place to get the easiest to read/understand, concise and all in one place info on everything from battery safety, charts on testing and specs, mech and juice reviews.....
Welcome to the wild world of vaping, once it get's in your blood, hold on, you're on for a ride! Hopefully you can save you some money and time by being smart and research, research, research, and one last bit of advice, try and wait until any particular vape item hits the vapers en masse and not just the "celebrity reviewers" like RIP Trippers, although he's excellent for building coils, to get a better since of what your average vaper thinks about something. This too has helped me. I've found Convict Vapes, while abrupt and a "rough around the edges" style, I've found their juice reviews to be spot on, and it was through them I discovered some of the best juices out there! Good luck!
