Just passing on what I've heard, but I'm not entirely convinced it's true.
I heard when they first came out that they did need to deep cycle charging (run it down to nothing and then charge it back up). Then I heard that this was no longer needed.
The factory User Manual does state that you should do the deep cycle routine a few times when you first get the device.
My own experience with my "Ole Blue" EZ Reader Basic has been that I am a habitual charger! I charge it up whenever the gauge shows half full. I enjoy my machine and always want access to my music. On long plane trips though (like to Taiwan), I have been forced to let it drain out while using it. There was no repurcussion from my frequent "half-full" charging.
I cannot tell you what to do. I can only state my personal experience!
