So I'm looking to replace the battery on my mid-2012 15" non-retina. Every review I've read is hit or miss in terms of a good battery brand. I found a Temark on amazon but even the reviews for that seem like it could be a crapshoot. I'm worried that I'll get a battery and it will wear out in a few months to a year. I've already had that happen with a cheapo battery for my 13". Any consensus on a good brand to get? Thanks!
