Aren’t MacBook Pro Batteries Supposed To Be Reliable?
While the batteries of most Mac laptops (especially the MacBook Pro) have been pretty reliable over the years, there are definitely a section of users who are having problems with their batteries. Before we talk about ways to solve those problems, you should have a look at your battery to make sure that it isn't bumpy or has gotten swollen with use.
If that is the case you should get in touch with Apple immediately about replacing the battery since they are very particular about issues like these. The Prevent Your Macbook Pro Battery from Becoming Defective article may help you in diagnosing major issues that might potentially be dangerous.
However, if the battery that you have in your MacBook Pro seems to be doing alight physically then there is a good chance that you are one of those people who began having battery problems after installing the latest Snow Leopard update. If your computer is randomly displaying the Service Battery icon and you have suddenly noticed that your batter life has halved then Snow Leopard is probably having problems with managing the battery hardware that is present on your MacBook Pro.
So What Is The Solution To My MacBook Pro Battery Woes?
If you suffer form the problem listed above or are worrying about what you will need to do in order to ensure that you will be getting the maximum life out of your battery what you need to do is try out the following steps in the order that they have been listed.
i. Calibrating Your MacBook Pro's Battery
The first thing that you want to do is try and calibrate your battery. In order to make sure that you are getting the most out of your battery this needs to be done once a month. Do make note of the fact that calibrating the battery won't help increase the battery life of your computer but will help make sure that your computer is giving you the right estimate as to the backup that the battery offers.

Follow the directions listed below to reset your PRAM.
1. Shut down your computer.
2. Locate the Command, Option, P as well as R keys on your keyboard and press them simultaneously with your left hand.
3. Turn on your computer and hold the key combo.
4. The computer will restart and you will hear the startup chime for the second time.
iii. Didn't Work? Try Resetting the SMC.
From Apple's website:
For Mac portables experiencing issues related to the MagSafe power adapter and/or battery, try:
- Unplug the MagSafe power adapter from the Mac and the wall power socket for several seconds.
- Shutdown the Mac. Physically remove and re-insert the battery (if it's removable) and startup the Mac.
iv. Restart The Computer In Safe Mode.
This is one of the last things that I resort to which is why its listed at the end. If all else fails, you can always try forcing your computer to initiate a Safe Boot sequence.
