Question about battery handling

[AntiPhoenix]

Ive read a lot of things concerning the better use of notebook batteries, but still i dont understand: i use my MPB as a desktop replacement so is it better to keep the adapter cable plugged in while the laptop is in use or plug it out and work on battery power?

Keep it plugged in and calibrate your battery once every month or so.
