I’m looking at About This Mac, but all it says MacBookPro (15-inch, Mid 2010), Processor 2.66 GHz Intel Core i7. It does NOT give me the model number of this laptop, and there appears to be 2 slightly differently priced replacement batteries for (Mid 2009 - Mid 2010), which I cannot see the difference for? So I really wanted to put the laptop model number into iFixit’s search box to ensure I would be buying the correct part and trying to insert into my olde laptop. How can I be really sure? or am I being far too cautious? Update (09/10/2021) bloody !&&*!!! looking down this page, i see the difference … it is clearly written, it is battery + tools or w/o … somehow that wasn’t apparent when looking earlier, but that could just be me … my apologies for my apparent stupidity, i have been suffering from a lack of sleep for a month, and it seems to be causing me some issues … RESOLVED!!! thank you
