Weeks ago, my ~16-month-old MBP battery menu displayed the message "service battery." I took it to Best Buy, which is where I purchased it (I have a 3 year warranty plan with them), and they arranged to have a replacement battery mailed to me, which is pretty weird because consumers are not advised to replace the batteries on their own. I got the replacement battery in the mail, but by then, lo and behold, the "service battery" notice was gone, and I have not seen it since. So now I have a new MBP battery on my hands. The battery is white, but MBP batteries (I think) are black, so I'm worried that Best Buy mailed me a shady third-party battery. Coconut Battery displays 83% capacity. Should I go to Best Buy try to have the battery replaced anyway? After all, it's a free battery, and my computer is bound to need a battery replacement within a year or so anyway. And I don't know whether it would be Best Buy's policy to mail me another battery for a future battery problem because they have already mailed me this one. But why is it white--does that mean it's nonstandard? Any thoughts?
