Check out http://www.batteryuniversity.com for some good information on the subject of batteries, specifically: http://www.batteryuniversity.com/parttwo-34.htm which discusses extending life on lithium-ion batteries.
With L-ion batteries the main thing that shortens battery life is heating a fully charged battery - exactly what happens when it is in a notebook that is plugged in to AC power. Ideally for the battery it is best to remove the battery when running off AC power, but past discussions on this mailing list have indicated problems with the loose plug (on these R3000Z models at least). The AC power can very easily be accidentally disconnected, and if the battery is not in place then you get an immediate shutdown and lose your work.
