    Kind of a silly question but I was looking to buy a battery replacement for my macbook pro. See signiture. My macbook pro uses a lithium ion battery. I noticed that eBay sells the same battery but in a lithium polymer type. Would it work in my computer? What is the difference really anyway? Should I assume that the lithium ion gets 300 cycles and the lithium polymer gets 1000 cycles. I know thats with the new uMBP but what about the aluminum MBP? Any help would be great.

    Here is the link to the battery I'm considering.

    Chemistry is not what determines the number of cycles your can use. For that you'll need to ask the manufacturer that makes the batteries.

    The pre-unibody MacBook Pros, regardless of Lithium Ion or Polymer, still only gets 300 cycles on average.

    Also, the batteries for the MBP have always been lithium polymer regardless of the model AFAIK.

    They are the same thing, if you would have taken two seconds to google you could have easily figured this out.

    Your "Li-Ion" battery is a Lithium Polymer battery.

    Why does it say Lithium Ion on my battery and NOT lithium polymer? What's the advantage? Larger capacity? So Steve Jobs selling the "new" lithium polymer wasn't really anything new. The marketing makes the perception that they are two different things.

    They are two different things. They're just not two different things when it comes to their application.
