Changed the battery in my 04 GP GT and went to start the car and it took longer to fire. Normally she fires up right away and now it takes a couple revolutions before it actually fires.

does it need to relearn because of the battery replacement?
 


Unless you changed the battery to one with different rated cranking amps, I bet you're fine. I'd give it a few days and see how it's doing. I don't believe the computer learns much from a starting standpoint since that doesn't effect your fuel trims much.
 


Could it have a been a "weak" new battery? There is a manufacturing date code on the side which is a small round sticker with a letter followed by a number. The letter stands for the month of mfg, A=Jan, B=Feb, the number is the last digit of year. A C4 sticker =March 2014. You may have bought a battery that was not fully charged and needed to be driven for a while to charge the battery.
 
mine will do this too if i take the battery out, will crank like 3 times then fire up vs a flick of the key normally. the pcm is just relearning.
