MacBook Pro 13" Battery Replacement
Battery life was less than one hour.
Easy. There are 10 screws that hold attache the bottom of the laptop: 3 long, 7 short. Make a small mark at the screw holes on the back cover to remember where the long screws insert. Once open, use some canned air to get rid of dust bunnies. There are 2 tri-tip screws that hold the battery in place. Be careful removing the battery cable from the logic board. I used the plastic wedge under the battery cable first to begin prying it off the board.
