I want to know when my MBP's battery was fully charged it's better to unplug my adapter and use my battery power or still let use adapter power?
I somewhere read that when MBP's battery was fully charged it's just use adapter for power and don't use battery, if it's true it didn't hurt adapter and reduce it's lifetime?
I have Macbook Pro 13" dual core(2.53)

Read what Apple has to say about notebook batteries:
EDIT for the lazy(es) who don’t want to read the links:
I hope this makes everybody happy.
Now… as a final note: the new unibody stuff coming from Apple doesn’t have removable batteries, however, the battery design is the same… those are lithium-ion batteries, no matter how fancy they make it look. Macbooks do not have a nuclear core in there, so the same rules apply, except that… well, you can’t remove it for storage, so more than ever, remember the 30 day rule.
