The new batteries are Li-ion and do not have memory's thus they do not ned to be conditioned. However, if you are going to have your laptop plugged in for extended periods of time several days or more, you will want to take it out to help it last longer.
Most laptop batteries come pre-conditioned. If the battery is not, it's usually 'deactivated' by a sticker or plastic tab that prevents the leads on the battery from making contact with the leads in the machine. You can condition a Lithium Ion battery but you need a machine or device capable. The conditioning process is usually a full discharge, 80% full charge, 20% trickle charge; it's meant to provide the maximum use. Years ago you used to be able to find 3rd party cell phone battery charges that used that charging cycle. I haven't seen one advertised recently and I've never seen such a unit for laptop batteries.
I agree qith Quickster, if you're going to use your machine on the ac block for an extended period, take the battery out. The battery will discharge itself over time. If you leave the battery in and have the ac block plugged in, the battery will keep recharging itself when it hits a certain level and will unneccesarily shorten its life.

I tried removing my battery on my new Acer TM291Lmi, because I leave it plugged in most of the time. After unplugging it, I tried to shut down the computer, and it gave me an error then rebooted. I guess this means that if the power cord gets yanked somehow without the battery in it, I lose everything
