If you are from US, check out www.ifixit.com. They may have the right battery for you. About Amazon, I don't know.
I would like someone to point the right battery for me too (Late 2011 17'' MacbookPro A1297 model), unfortunately in Europe it is really expensive..
Anyway, I hope you solve your case.
I got one yesterday form amazon, it's pretty good so far..got it installed. has 1 cycle battery, calibrating it right now as we speak...want to clarify..
Calibration method is...
1. right now the laptop is 69% (came with)
2. I plugged in the charger..
3. wait for it to go green, with extra 2 hours...
4. unplug charger, use laptop until it dies...
(at this rate you can set your sleep settings to never, play videos, go crazy to make the battery run down faster? correct me if I'm wrong)
5. when it warns you that its gonna die soon, leave it un-charged for 5 hours + and then re charge it again till 100%) ????

Unless that battery comes with specific instructions for calibration, that method is placing a tremendous amount of stress and wear on the battery unnecessarily. It is far, far from ideal to allow a lithium cell(s) to go that low, and even worse to allow it to remain that low for an extended period. Lithium cells HATE low voltages. They absolutely despise this.
With Apple OEM batteries, calibration is NOT required on any "non-removable battery" (in other words, post 2008) (in the case of incorrect reporting, a SMC reset is what is generally advised). Some 3rd party Makers suggest calibration with their 3rd party batteries - I'm not sure why they do given most modern LiCo/LiMN/LiPo's do not need calibration, and reporting accuracy tends to become more accurate with just normal usage.

When I got this refurb-macbook pro 15, they came with a 60w battery charger...should I purchase a 87w instead?
It is not necessary, but the battery will charge slower, and if you use the computer for extremely intensive work, the battery can slowly discharge even while plugged in. Provided the battery is not discharging during the work you do (which can affect the battery's longevity in extreme cases), you should not have an issue.
okay I won't get one. lol. I know this laptop won't last 5 more years lol, I replaced the memory to 16gb and got a SSD. cos it was so slow before all these update, I'm trying to budget for college right now so I went for a refurb MacBook Pro, i don't like how the newer ones that you have to buy so many dongles. my gf has it. its nice and all but not what I need. I'm gonna save money for another 2 years and get the retina maybe..
