I would go to Apple and just buy the correct replacement battery. This one is not worth the headache of trying to get the laptop to see it and then take the charge.
No, I would not recommend this to a friend

cheap replacement but short life battery.
I purchased this battery for 88 bucks about a year ago. I see that the cost has gone up for this product but doubt that the quality has gotten better. This battery only lasted a year and now I am shopping for a new one. Doesn't hold a charge for even 40 minutes nearing the end of one year of owning it. And yes I do recalibrate the battery from full charge to completely dead to refresh the life cycle on the battery and doesn't seam to change performance.
