How do you replace your MBP battery?

I have a 2009 model. IT is telling me I have to replace my battery soon. How long would this take? I dont have a warranty, so can I just go to the Apple Store?

Yes, you can take it to Apple, but first check its health, rather than depend on IT to tell you if you need to replace it. Use iStat Pro (free) or iStat Menus ($16) to get accurate readings of your battery, temps, fan speeds and much more.

It should be. I'd call ahead and make sure they have the replacement in stock. From the link I posted:

How long will battery replacement service take?
Length of time to complete the battery replacement will depend upon the repair location and availability of service stock. In general, the following replacement times apply:

Apple Retail Store
Depending on inventory availability this may be replaced the same day. Make a reservation to meet us at the Genius Bar.

Apple usually has these things in stock. It should not take more than a day, but if they are very busy or out of stock on the battery it may take a few days.
