What I have heard is not that Li-Ion don't liked to be charged above  
a certain level, but rather, that they don't like full discharge.   
Ie, better to let it run to 40% and then plug it in than to let it  
run out.

Same goes for your cell phone -- plug it in every night whether it  
needs it or not.

However, in reading wikipedia (http://en.wikipedia.org/wiki/ 
Lithium_ion_battery) it seems there is some tuth to what we both have  
heard.
