batteries - How to calculate battery life with a given load?


I am not very good at electricity things so any help anyone could give me would be fantastic. Here goes:




  • I have a battery (for power tools); it is 18v and 1500 mAh (imagine DC).





  • I'm trying to get it to power a tool that is designed to take 120V and 6 amp (AC).




Is there a way to calculate how long the battery would last? I read the article on "How to calculate Battery Life" and it was extremely helpful... but I have more questions. Does the AC/DC conversion have any effect on battery life? What affects do volts have on battery life? Is there an equation to calculate this?
