My Mid-2012 15" NON-Retina Macbook Pro's battery status has changed to "Condition: Replace Soon". Its battery drains pretty quickly now, so I wish to get a replacement. I want to make sure I order the right thing from eBay. I've never ordered or replaced a battery before, so I'm not confident. Are any of these correct? https://www.ebay.com/sch/i.html?_od...nkw=Macbook+Pro+2012+Battery+15+inch&_sacat=0 Also, are these good deals for one? PS: Does anyone know what to call those little adapters used to shorten your charging cord by plugging it in place of the second half of the cord? I want to buy one, but have no idea what to search. Bonus points if you can link me.
