Hi Just in case anyone has not thought of this, I thought I would pass on a tip about maximising battery life in the Bookport. I have several flash cards, and on all of them I load a mixture of text and audio files. I then listen to my audio files whilst my bookport has a good battery life. When the Bookport tells me that my batteries need changing, I switch to listening to my text files and get about six more hours out of the batteries that way! Ok, it means that I read a mix of things at different times, but it works well for me. Hope this is of use to some of you. Best wishes Donna Slater.
