I have a 13 inch MacBook Pro that is telling me I have to replace the battery soon. I bought it in 2010 and this is the only problem I have had with it so far. I'm trying to find a replacement battery for it, but I'm not sure if it will fit my laptop or not. Here is a link to the battery I was looking at, http://www.staples.com/AppleMB771LL...k-Pro-Notebook/product_IM1V11775#desc_content . I have a staples gift card so I could get the battery for next to nothing, but I just don't know if it will fit. Can please help me????
