Battery Replacement

My mid 2012 MacBook Pro has been telling me for well over a year that it needs service. I checked and it had more than 3,000 cycles, so it was past time for a replacement. I ordered one, and went through the process of swapping new for old this afternoon. A little disconcerting having the guts of my workhorse open to the world, but all seemed to go smoothly and I should now have a battery that lasts longer than a half hour (plus no more nagging from the OS).
