car battery
 

I own a 2000 boxster. Was told by the dealership that the battery is low. I would like to replace the battery. Hoping that this is something very easy to replace, that I can do. What type of battery do I need to buy? Can I just but any battery at AutoZone?
Also, can someone tell me what the steps are to replace a battery. I know where the location of the battery is and I have my radio code, if needed.
Thanks
