Question Any batteries you recommend for the 2011 13in and 2012 15in Macbook Pro?

[DCtx88]

Would love to know someone who replaced, tested long term, where did you get your battery from, and how did it fare? I see alot of issues where the batteries crap out or dont last besides OEM, but maybe I am wrong, and would like to know besides ifixit and owc, what places you recommend?

If I recall, the batteries in MacBooks are sealed in, meaning they are not easily replaced.
