I needed a new battery for my 2010 MacBook pro 17"

My Problem

The battery was lasting less and less

My Fix

Easy: I did not have a 3 wing tipped screwdriver, but I use a small flat one to remove the 3 screws holding the battery.

My Advice

WARNING: Apple, hides a third screw holding the battery under a small plastic cover in one of the corners of the battery. You need to remove 3 screws to replace the battery
