I goosed the battery on my HP laptop completely by leaving it in all the time while running off the power supply - using it as a UPS effectively.
On my Toshiba laptop I take the battery out whenever I'm running off the PSU (such as right now!). This is the best method as a Lion battery has a limited number of charge/discharge cycles and should be used only when truly off the mains power to extend its life.
The disadvantage is that if I accidentally move the small DC power plug on the back of the laptop I can lose everything in a moment!
