Alright, I'm currently using a mid-2012 15'' MacBook Pro that I bought used off of an ebay seller. Said seller claims they bought it in december of 2012 and the expanded warranty runs out jan 2016. What I'm really confused about is coconut battery claims this laptop was made in jan 2013 and the battery was made in november of 2012. I don't know how coconut battery gets its information, but I'm having some very confusing time frames going on here. Any ideas?
