whats the diffrerence between active and passive pick-ups.....i want to change the pick-ups on my guitar but havent got a clue about pick-ups or the differences in them

and can u fit active pick-ups to any guitar because my other guitar has active pick-ups i think but it needs a 9v batery?

helpme please

Unless you have a good amp (which you don't) it's not worth changing pickups as you won't notice the difference.

I really wouldn't worry about the whole active/passive pickup thing unless you actually have active pickups.
