Congratulations on selecting a great topic. Best place to start your research is right here on the Forkliftaction.com website. There is a huge amount of forklift information on this site. First step go to "Industry News", click on "search news archive" click on "View our past Newsletters" (near top right hand corner of the page).....or look through the options at "type of story".....look particularly at "Feature story" (there are about 160 of them) or "all News"
We did a Feature article on the Battery sector of our industry in September 2009...see www dot forkliftaction /news/newsdisplay dot aspx?nwid=7634

and I am sure that you will get a lot of help if you ask some more specific questions on this discussion forums.....remember people are busy....so focus on specific questions.
