Apple just replaced my MacBook pro battery. Since the replacement it takes significantly longer for my machine to boot up. Any thoughts?

Try resetting the SMC https://support.apple.com/en-us/HT201295

Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379

If no change verify in >System Preferences>Startup Disk Manager your Macintosh HD is selected
