Whether to use laptop permanently linked to power supply

For years I have used my laptop with the power supply remaining connected, even if the Li-ion battery is showing fully charged. (Obviously that would maintain the battery at 100%).

Now my friends are advising me that this is bad practice and will wear out the battery quicker (although the battery that came with my Acer lasted four years doing this).

They say that I should charge the Li-ion battery to 100%, then disconnect and run it down to 5% or 10% before recharging to full again.

As this is such a basic issue I am not citing specific models, but can do so if there is not one right answer across the board.
