laptop question

is it a good idea to leave the battery in the laptop constantly?

i read somewhere, it counts as a charge. Leaving a fully charged battery in a laptop while powering off the mains, does not do the battery any favours i think. It happened to my sister, she left it in there constantly while running of the mains and eventually the battery died and was not usable.
