Just replaced the battery of MacBook Pro Early 2011. Shipment was blazing fast. I ordered on Saturday and received the battery on Monday morning. It took me just 15 minutes with the right tools to change the battery. iFixit's step by step guide helped me to accomplish the task perfectly in the right way.
I ordered a replacement battery from iFixit to squeeze some more life out of my early 2011 Macbook Pro. The new battery is great, my computer lasts way longer now which is super helpful. The guide helped me easily swap out the battery in less than 20 minutes. :)
How much weight can I save by removing the optical drive?

You can save a lot of weight if lets say your installing a solid state drive or putting in a second hard drive but if you know that you use the CD/DVD disc drive a lot then you might just want to leave the drive alone.
