How to Replace a MacBook Pro Battery?
As mentioned above, MacBook Pro battery can be easily removed and replaced. This is a least expensive method as all you need to do is get a new battery and replace it with the one that is damaged.

Now, contact an Apple Authorized Service Provider or Apple Online or approach an Apple retail store. Ask them for a replacement battery for your 13", 15" or 17" MacBook Pro. If you visit the Apple store yourself, you will get your replacement the same. Batteries received by post or courier will take about 5 days to reach you.

First and foremost shut down your MacBook Pro laptop completely. This will help avoid any kind of damage to the internal components of your laptop. Once you shut down the computer, wait for the laptop to cool off. Sometimes, after using your laptop continuously, the internal components tend to heat up.
Disconnect any cables or external devices connected to the laptop. Now, place the laptop on a firm, even surface, that is scratch free. The laptop should be facing face down, that means, the underside of the laptop should face you.
You will notice there are two switches towards the center of the bottom case. Using both your hands, slide the switches towards the back of the machine. You can observe red colored background beneath the switches, when slid the correct way.
The minute you slide out the battery correctly, the battery will pop out of the bay. Remove it from the bay and place it aside. Be careful you do not mix the new battery with the old one. Also be sure you do not scratch the casing over the battery.
Now, remove your new battery from its packaging and place it in the bay. Push it back inside by sliding the two switches behind. Once in place, release the switches to hold the battery in bay. Charge your battery and then switch on your laptop. Your laptop will function as good as new.
