Should laptops remain plugged in when their battery is 100% charged?

I want to expand the lifetime of my battery which is a 6-cell lithium ion. I've read somewhere for Li-Ion cell phones that we should let the battery die before charging it. Is that the same with my laptop? My laptop is always plugged in. Should I not use it plugged in and keep on using it on battery and charge when low?
