That would explain the jittery revs. It is a common thing, just take the car out for a 15~20mins spin would take care of it =)

^^^^^This and what yarisugi said. When my car was idling rough after the battery replacement, CTScott explained pretty much what you and yarisugi are saying. A few hours later, I drove my car and the idle issue had mostly ironed itself out within 20 minutes and within an hour or so was pretty much as good or better than before the battery replacement.
