Which aftermarket battery to get for mid 2015 MBP15?

[shaocaholica]

My mid 2015 15in MBP needs a new battery. I'm seeing lots of generic $60 batteries on Amazon, generic $45 on ebay, and ifixit has its 'branded' battery for $109. Are these all the same? Came from the same factory? Which one should I get. I don't need the top 1% performer but I also don't want it to fail prematurely either. Going to give this MacBook to a family member.

For a battery I'd probably play it safe and go ifixit. At least you know they're a reputable brand and the battery will have been produced to their safety standards.

My 2-power battery is holding up reasonably well after 5 years.

I don't think I have '2-power' batteries in the US.

Does anyone know what the manufacturer string is for iFixit batteries?
