My laptop is four years old, and yes the battery is aging.  When I bought the 
laptop there were instructions that if a laptop is used mainly on mains, you 
should run it on battery, say once a month or so, until you are down to 10%.  
It was claimed that the periodic discharge in this way actually lengthens the 
life-span of the battery.
