"Model Identifier: MacBookPro5,1" is what I was after. You have the same model as I do. This is the Apple replacement battery (identical with the original):

This Google search finds a variety of third-party replacements. I know nothing about any of them, but on the basis of more than ten years of daily experience reading and answering posts in the Powerbook and MBP forums here, I need to caution you. Many, many people who have bought third-party batteries at too-good-to-be-true prices have found that they were indeed to good to be true: their cheapies have frequently refused to charge at all, failed to hold a charge, failed to repport their condition accurately, couldn't be calibrated, didn't deliver any low-battery warning, drained so suddenly as to shut the computer down (losing all unsaved work), or any combination of the above. So I'm not really sure you get what you pay for when you pay a premium for an Apple battery, but I'm quite sure that when you buy an El Cheapo battery, you
don't get anything you
aren't paying for. And you may not be getting what you need. So choose a third-party battery at your own risk, and please let us know what you choose and how it works out for you.
